Hairy frogfish video

Hairy frogfish video makes for compelling watching, especially one in which the fish actively lures potential prey. This video from Gorontalo shows a Hairy frogfish doing exactly that.

Striated or Hairy?

The scientific name of the fish in the Hairy frogfish video is Antennarius striatus. As such, it is commonly called Striated frogfish. This particular fish species has such a variable appearance that neither “striated” nor “hairy” accurately describe each individual found in nature. That includes the one in the video from Gorontalo. The fish’s environment determines its exterior appearance to a large extent. In fact, if a particular frogfish moves to a different environment, it will change appearance within three weeks to match. That means that the elongated blotches or the long filaments on the skin may not be apparent on any particular individual fish. It can sport almost any color.

Notice the lure

Moreover, the best feature for positively identifying Antennarius striatus is its lure.

A Unique Lure

The first dorsal spine in many frogfish species is free moving. Called an illicium, this spine acts like a fishing pole. At the end of the illicium of Antennarius striatus is a fleshy lure. The unique lure or esca of this species of frogfish is long, extending perpendicularly from each side of the lure. Many descriptions of this frogfish say that the lure looks like a worm, However, that is not particularly true of the one seen in the Hairy frogfish video from Gorontalo. Take a look and notice its pale color and spots. This one looks more like a shrimp dancing above the rubble. When not in action, the lure will rest on the forehead of the frogfish.

Hairy Frogfish Video

As you watch this video from Gorontalo, notice the way the frogfish pulls itself along the sandy bottom. It is using its pectoral fins. This is a distinctive movement of various frogfish.

Judging by how active it is, both in flicking its lure and pulling itself to a new position, this frogfish is clearly hungry. It is on the hunt! Many frogfish species, including the Hairy frogfish, have a large mouth. As a result, a frogfish can extended its mouth forward and swallow prey as large as itself. That also means that its stomach has plenty of room.

Typically, frogfish lie motionless using its well-adapted coloration to remain unseen. The videographer never saw this Hairy frogfish catch anything. Perhaps too much movement was to blame. 

Hairy frogfish usually eat other fish. Unlike other species of frogfish, the lure or esca of Antennarius striatus has an additional feature. It is able to secrete a scent that attracts unsuspecting prey to its wiggling lure. This species also can live in waters deeper than other frogfish species. It is found in seas worldwide, except in the Mediterranean and the Arctic. Although the individual seen in the video is very small, it can grow up to 22 centimeters in length.   

Hairy frogfish are only found at a few of Gorontalo’s muck diving sites. This sites are best suited for experienced divers with excellent buoyancy control. For your chance to watch a Hairy frogfish in Gorontalo, please book your dive trip with us.

Plastic Reduction Policy

Plastic reduction policy at Miguel’s Diving Gorontalo revolves around the four R’s: Refuse, Reuse, Recycle and Reclaim.

Plastics Policy & Pro-active Waste Reduction

Some may be surprised that a local dive center like Miguel’s has a plastic reduction policy. Actually, we have had one in place for many years. Guests will notice right away our efforts and we encourage participation.

Refuse

The first action of our plastic reduction policy is to refuse. Our staff bring green bags to stores and local markets. This way we do not need plastic bags. We also refuse to buy individually wrapped snacks and those with plastic trays. Instead, we provide wafers, which can easily be shared among guests. Traders at Gorontalo’s Central Market know that we are looking for the day’s sweetest pineapple when a staff appears with our big plastic box complete with lid. But that brings us to the second R.

Reuse

Using containers for daily fruits is one way we refuse single-use plastic bags. We reuse sturdy plastic boxes for the fresh, local fruits that we provide guests after a dive. These are also easy to clean, helping maintain necessary sanitary conditions.

plastic water refill
A guest refills his bottle

Miguel’s Diving does provide the standard plastic water bottles containing drinking water. We purchase these from a Gorontalo water company that employs local people. Rather than letting those bottles become single-use plastic, we provide a pen with permanent ink. Miguel’s Diving also encourages our guests to write their names on their bottle. After a dive, a quick glance determines which bottle belongs to which guest. Some guests bring their own re-useable drinking containers, which is even better. We provide a large five-liter refill station of local, purified water. Our daily briefing includes explanations about water refill as part of our plastic reduction policy.

plastic reduction policy
A reuseable lunch box

For lunches, we have long used re-useable lunch boxes with lids. Even the plastic spoons are rewashed and eventually end up in the coffee station. Rather than single use plastic or Styrofoam meal containers, ours are literally used hundreds of times. 

Recycle

Giving away a sack of used plastic bottles

We have no trouble giving those plastic water bottles away at the end of a dive day. Neighbors of the dive center, who have limited income, drop by to collect them. Gorontalo has a plastic bottle recycling center, which pays for plastic bottles.

Reclaim

Miguel’s Diving staff take part in annual local beach cleanups. The local government is the sponsor. Local officials use these events to educate coastal residents on cleanliness and hygiene. For a number of years now, Gorontalo City government offers free garbage pickup. Residents are encouraged to leave garbage in a container or small pile in front of their houses for daily pick up. This has greatly reduced the amount of plastic thrown in the rivers flowing through Gorontalo City.

Local divers clean up underwater

The biggest impact Miguel’s Diving makes on reclaiming discarded plastic and other human-generated rubbish is our daily reef sweeps. During each dive, Miguel’s Diving staff check the reef for plastic or anything else that does not belong. Our staff estimate that 90% of rubbish on the reef is single-use. We thank guests who help us keep the reef clean. Moreover, the captain will steer the boat toward any floating rice sacks and pick these up. They cause the most immediate damage to the reef. A rice sack easily tangles onto hard corals, blocking necessary sunlight and killing the coral within a few days. Travelers to Gorontalo remark how clean and neat Gorontalo City is. Divers notice how relatively clean Gorontalo’s marine areas are.

MIDE 2019 features Gorontalo Marine Environments

MIDE 2019, the Malaysia International Dive Expo, featured a presentation on Gorontalo’s marine environments. Staff from Miguel’s Diving delivered this full-color session from the stage of the Indonesia Pavilion.

MIDE 2019: the Malaysia International Dive Expo

The 14th Malaysia International Dive Expo took place 3 – 5 May 2019. It is also called MIDE 2019. Malaysia’s famous Putra World Trade Centre or PWTC provided the venue. The Exhibition opened daily to the public at 10 a.m. It closed nightly at 7 p.m.

Gorontalo’s Marine Environments

On Saturday, 4 May, Miguel’s Diving accepted the invitation from Indonesia’s Ministry of Tourism to deliver a presentation about Gorontalo. We selected the topic of Gorontalo’s marine environments. Much variety in environments means much variety in diving. After introducing the team of Miguel’s Diving, our staff explained the nature of Gorontalo’s geography. Ancient coral uplifts form the rocky northern coastline of Tomini Bay. Moreover, the soft limestone erodes over time and forms dramatic underwater scenery. This also creates multiple environments within a short distance.

Gorontalo’s pristine coral walls actually form part of the continental wall of Sulawesi. On these deep walls, our famous Salvador Dali sponges grow in surreal shapes and super sizes. Each is unique in profile. Moreover, they come in a variety of colors. A top the coral walls lies a shallow ledge, sometimes measuring only a meter wide. Different marine life live here, giving divers another type of environment to experience in the same dive.

Another characteristic of Gorontalo’s geography is submerged points. These are frequent features found along the coastline. The bay’s longshore currents hits theses points, creating a swirl of activity. Schooling pelagic fish and strange creatures of the deep ocean can be seen in these locations.

In other places in the world, having a single coral pinnacle is considered special. However, in Gorontalo, multiple pinnacles compose several dive sites. Gorontalo’s famous whale shark sightings most often occur along a row of coral pinnacles.

Caverns also occur in Gorontalo. However, none of these are underwater caves. Cave diving requires technical skills, certification and preparation. Caverns offer a safe alternative, since the way out is always clearly visible.

Muck basins alternate with other marine environments. Like all of Gorontalo’s marine environments, these are actually quite small. As a result, this means that marine life is more crowded than in locations where muck diving is found in a large area.

Gorontalo even has a couple of artificial reefs. Specifically, these are historical wrecks.

Gorontalo for Malaysian Divers

MIDE presentation
Fans of Miguel’s Diving at MIDE presentation

Gorontalo is an excellent destination for Malaysian divers. Pristine dive destinations are often difficult to reach. Not so Gorontalo! Air Asia offers daily flights from Kuala Lumper’s KLIA2 airport to Makassar (UPG) four times weekly. The connecting flight to Gorontalo (GTO) lasts about one hour ten minutes. This is the route we recommend for Kuala Lumpur based divers.  

Additionally, Gorontalo’s diving season is the opposite of most peninsular Malaysian destinations. Our season runs mid October to mid May. Officially it is November to April. Now there is no reason to cry during monsoon-lah. Come dive in Gorontalo! For many Malaysians food can be an issue. Food in Gorontalo is halal.

Even if you missed our presentation at MIDE 2019, you can still book your dive trip with us.

Arothron immaculatus Emerges from Hiding

Arothron immaculatus or the Immaculate puffer is rarely seen in coral dense environments typical of Gorontalo. But one day it make a surprise appearance.

Hiding on a Sandy Bottom

Arothron immaculatus
An Immaculate puffer tries camouflage

One day a dive master from Miguel’s Diving spotted the bright yellow eye of a fish trying to hiding itself in the white sand bottom. By the way, one of the common names for Arothron immaculatus is Yellow-eyed puffer. Knowing it had been seen, the fish tried to flick more sand over its oval-shaped body. However, its brilliant eyes and strange tufts on top its nose remained clearly visible. It shifted around closer to a mass of corals, revealing a mottled pattern as the grains of white sand began to fall off its body. After posing for a few photos, the fish decided to flee across the white sand bottom. It even and pale color could help it hide undetected there.

Arothron immaculatus around the Pacific  

This Immaculate puffer can be found through Indo-Pacific waters. It clearly prefers sandy or silty bottoms near coral reefs or shallow estuaries. The Arothron immaculatus seen in Gorontalo was living at one of our alternate muck diving sites. The site is called Mystic Point. It is close to the estuary of Bone River. That dive site is known for its relatively poor coral but has a white sand bottom that is rare for our area of Gorontalo. That site has marine life only found there, like the Twin-eyed goby and the Immaculate puffer. This puffer can also be found near mangroves and seagrass beds. Western Gorontalo has those environments, so perhaps this puffer can also be found there.

This puffer is usually solitary and rarely in large numbers in its environments. It is found between three and thirty meters. It is mostly carnivorous.

Arothron immaculatus has some distinctive markings that help confirm its identity. Apart from its beautiful eyes and nose tufts, its body is basically plain, unless it is sporting the botches of its camouflaged mode. Moreover, it has a large dark patch around its pectoral fin base. Also, it has dark upper and lower margins on its tail fin. A similar species is Arothron manilensis. However, the Manila puffer has distinct thin lines on its body.

The Quixotic and Toxic Puffer

Puffer fish have quite distinctive bodies. This includes tough skin and a dental plate in their beak-like mouth. What they lack is more notable. They lack fin spines and ribs. As a result, they can inflate their stomachs with water when afraid. Moreover, their skin, gonads and liver contain two toxins. These are tetrodotoxin and saxitoxin. Some species are more toxic than others. Because different puffer species have similar body shapes, identification is most accurate when using color patterns.

For your chance to see one of Gorontalo’s puffer fish, please book your dive trip with us.

ADEX 2019 Welcomes Back Miguel’s Diving

ADEX 2019 welcomes back Miguel’s Diving after an eleven year absence. Believe it or not, Miguel’s Diving last participated in this regional dive exhibition in 2008.

ADEX 2019 – Bigger by Far

This year’s Asia Dive Expo actually marked the event’s twenty-fifth outing. Back in the earlier years, the expo was much smaller. When Miguel’s Diving last participated, the square footage was under 2,500 with visitors totaling under 20,000. ADEX 2019 filled over 10,000 square feet at Suntec City Convention Center in Singapore. Last year’s expo gathered over 40,000 consumer visitors. About half that number of trade visitors came. In 2006, Miguel’s Diving sponsored a Lucky Draw.

As in previous years, Miguel’s Diving filled a regular three by three meter booth. This year’s location was K16. The booth included photos of Singapore-based divers who have dived with us in Gorontalo. Also, one panel of the booth displayed beautiful underwater photos. One of our Singaporean divers took these photos during his third trip to Gorontalo last December. 

Friends Old and New

One of the highlights of this and any exhibition is too meet many enthusiastic divers from around the world. Not only did Singapore divers visit the Miguel’s Diving booth. So did divers from Dubai to Taiwan.

Fadel Muhammad ADEX 2019
Member of Parliament Fadel Muhammad visits

Another great benefit of dive expos such as ADEX is the chance for reunion. Many who had previously dived Gorontalo with us, stopped by to say hello and catch up on the latest news. This included dive buddies from Malaysia and Indonesia.

We felt especially honored that Minister of Parliament from Gorontalo Prof. Dr. Ir. Fadel Muhammad attended two days of the expo.

Campaign against Single-Use Plastics

Each year ADEX highlights an important aspect of marine environment. ADEX 2019 launched a campaign against single-use plastics. Too many of these often end up in the world’s oceans.  In fact, people dump eight millions tons of plastics into the ocean annually. According to the World Bank, China, Indonesia, the Philippines and Vietnam discard the most plastic into the ocean.

Singapore, the host of ADEX 2019, consumes 1.76 billion kilograms of plastics each year. This statistic comes from the Singapore Environment Council. Unfortunately, less than twenty per cent of that is recycled.

Anne the plastic queen
Plastic as Fashion

Indonesian ocean artist Anne K. Adijuwono staged a fashion show featuring 25 endangered species. She also created a mural using plastic waste. Mermaid Dewa designed outrageous costumes for a traveling troupe leading the cry against single-use-plastics. 

Miguel’s Diving has long had a plastics policy in place. It involves four actions. They are refuse, reduce, recycle and reclaim. For your chance to participate in our efforts to reduce single-used plastics bound for the ocean, please book your dive trip with us.

Whether or not you had a chance to see us at ADEX, we would love to have you show you the hidden paradise of Gorontalo. Please book your dive trip with us.

Deep Extreme Indonesia 2019 Features Miguel’s Diving Staff

Deep Extreme Indonesia 2019
Underwater Talks

Deep Extreme Indonesia 2019 features one of Miguel’s Diving staff as guest speaker. Our senior dive master and marketing assistant Yunis Amu participated in UW Talks. These talks featured various Indonesians well known in the dive industry. We are very proud that he received this invitation.

Manual UW Settings for Beginners

In his UW talk, Yunis targeted divers who use only automatic settings when photographing underwater. He challenged them to advance their skills and use manual settings. This would give much better results in underwater photography.

After introducing himself, he divided his UW Talk into several sections. First was Aperture or F-Stop, then Speed and then ISO. He included a section on Strobes and ended with cautions about Buoyancy. To support his UW Talk, he shot a variety of marine life common in Gorontalo. That included Salvador Dali sponge, red sea whips, Thorny seahorse, lionfish, Harlequin ghostpipefish and sea fan. These he shot at various settings to illustrate the impact a change of settings would have on a particular photo.

Yunis Amu in action

He completed this UW Talk for Deep Extreme Indonesia 2019 with several dramatic and excellent photos. These included a rare bell jellyfish, nemo and nemo eggs, whale shark in sunburst and seahorse shot with black background and bokeh style. All underwater photographs presented were original and without any computer editing.

DEEP Extreme Indonesia 2019

Miguel’s Diving has participated in this annual dive expo since its inception. Deep Extreme Indonesia certainly maintained its reputation as a well-run, regional dive expo this year. The variety of exhibitors is one of its hallmarks.

Two of Miguel’s Diving staff attended the expo and promoted diving in Gorontalo.

Meanwhile back in Gorontalo, our staff hosted international divers, providing great service and great diving. This included five whale sharks and 35 meter visibility!

Dogtooth Tuna Video

Dogtooth tuna video recently shot in Gorontalo is now available for viewing.

Tuna on the Reef Edge

Although Gorontalo is famous for its Yellowfin tuna, the tuna that divers will most likely see here is Dogtooth. This tuna is one of the apex predators like Giant trevally and large groupers.  They eat smaller schooling fish that thrive off Gorontalo’s coral walls. These include fusiliers, fairy wrasses, scads and rainbow runners. As evidenced in the Dogtooth tuna video, these fish are curious about divers. As a result, they will often make several passes, giving time for visitors to get cameras ready.

Lucky Dogtooth Tuna Video

A prime dive site for viewing larger schooling fish is Buffalo Head Point.  It numbers among Gorontalo’s many submerged points. These points jut away from the cliff above water and away from the underwater coral wall. Moreover, this position interrupts the smooth flow of the area’s longshore current. When a strong current is running, schooling fishes will congregate off these submerged points.

On the day this Dogtooth tuna video was shot, the current was moderately strong. Also, the plankton count was high. Notice all the backscatter in the video. That is living plankton. As a result, schooling fish that feed on plankton gathered in abundance. Notice the Blue-and-yellow fusiliers in the video. This is the kind of fish that fast swimming Dogtooth tuna love to eat.

Although dive staff often see large fish in these conditions, everyone was surprised with the close encounter with schooling Dogfish tuna.

Tuna without Scales

The scientific name for Dogtooth tuna is Gymnosarda unicolor. Unlike other sarda, this one lacks scales. Hence its official name, since gymno means “naked” in Greek. This silvery fish is considered unicolor, in contrast to other tunas like Yellowfin or Bluefin. It sports a single, undulating lateral line.

dogtooth tuna video

Divers can easily recognize this streamlined fish. It has white tips on its upper and lower back fins. The caudal peduncle also shows a white area. These white markings are clearly visible in the Dogtooth tuna video. Also, notice that the fish’s upper jaw extends even with its eye. This fish swims with its mouth open, showing its many conical teeth.  

The average size of Dogtooth tuna that divers see swimming along Gorontalo’s coral walls is between 40 to 120 centimeters. Mature fish can measure up to two meters in length and weigh up to 120 kilograms. These swim in depths as deep as 300 meters. Miguel’s Diving staff estimate the larger ones seen in the Dogfish tuna video weighed about 50 kilos!

This tuna species lives in tropical waters of the Indo-Pacific region.

For your chance to see Dogtooth tuna in Gorontalo, please book your dive trip with us!

Thysanoteuthis rhombus egg masses

Thysanoteuthis rhombus egg masses are rarely seen. However, one of them drifted near Miguel’s Diving speed boat during a surface interval. It looked like a giant pink and transparent version of a child’s slinky toy.

Thysanoteuthis rhombus egg masses

Mysterious, deep water squids lay eggs in spirals. A gelatinous case holds the long spirals together. After the fertilization process is complete, the egg mass will float with ocean currents near the surface.

Thysanoteuthis rhombus egg masses can measure up to 1.8 meters in length. Each tiny pink pearl is actually a squid egg. A single egg case carries between 24 and 43 thousand eggs inside its transparent case. The egg mass the Miguel’s Diving staff discovered measured about one meter.

Detail of diamond squid egg mass

Thysanoteuthis rhombus egg masses drift with strong currents in warm tropical waters. Seeing them is indeed a rare event. This occurrence marks only the second time Miguel’s Diving staff have discovered this type of egg mass during our 16 years of operation.

Diamond Squid from the Depths

This deep water squid is sometimes called diamond or diamondback squid. It has distinctive fins that run its body length. Its scientific name, Thysanoteuthis rhombus, describes its rhombic shape. Its arms are noticeably short. However, it can grow up to 100 centimeters and weigh up to 30 kilograms.   

This diamond quid lives in the deeper parts of the ocean during the day. Trawlers have found it at depths below two kilometers! Since Tomini Bay, where Miguel’s Diving operates, plunge to twice that depth, no one should be surprised to learn deep sea squid live in Gorontalo waters. At night, it will rise nearer the ocean surface. It is found worldwide in tropical and subtropical seas.

The beautiful Thysanoteuthis rhombus egg masses come from mating pair. The diamond squid are the only cephalopod known to remain in the same mating pair for life. Fishermen observed that if one of the pair is caught, its mate will remain in the area until it is caught as well. Diamond squid naturally live about one year.

Deep Water Encounter

This squid is fished commercially in Japan. Other predators include tuna, swordfish, sharks, Rough-toothed dolphins, as well as False Killer and Sperm whales. Miguel’s Diving staff have observed all of those predators in the Gorontalo waters of Tomini Bay.

Although divers are unlikely to see these deep water Thysanoteuthis rhombus egg masses anywhere in the world, our guests often see other pelagic species. For your chance to meet deep water marine life in Gorontalo, please book your dive trip with us.

Melibe viridis video from Gorontalo

Melibe viridis is a highly unusual nudibranch found throughout the Indo-Pacific region. It uses an oral hood like a net to capture live prey to eat.

Melibe viridis hunting for prey

A Camouflaged and Cumbersome Nudibranch

Imagine the surprise of divers to see a brownish mass twisting in the current over a muck diving site! That turned out to be a rarely seen Melibe viridis nudibranch.  Viridis is a term describing young foliage. This is an apt description of a creature with parallel branches growing at spaced intervals and perpendicular to its body.   Without movement, this creature would blend perfectly into the coloration of the ocean bottom. Numerous bumps  and tufts mark M. viridis distinctively. One diver captured these movements in a dramatic Melibe viridis video. This one measured about 8 cm long. Notice that its front left branch is stripped of its warty bark.

M. viridis video from Gorontalo

On another day our divers found one measuring only two centimeters. This second M. viridis had somehow lost all its branches. Some had started growing back. However without those distracting cerata, divers could clearly see the way this nudibranch crawls on the long central foot. It leaves a mucous trail. This small one appears the second part of the video. Water that day was much greener than the previous day. 

Watch this nudibranch twist its body and launch itself into the current. With twisting movements of its body, it succeeded in moving farther along the sloping sand bottom.

Melibe viridis Searching for Food

Melibe nudibranchs have a unique way of searching for food.They are active carnivores and use an oral hood. Imagine the divers’ further surprise to watch this nudibranch hunt for food.

In a rhythmical manner, the nudibranch will cast its hood forward. On the inside edges of the oral hood, this type of nudibranch has short papillae, which sense movement. Sometimes, these are visible in the video. The Melibe tries to trap small crabs and shrimps its oral hood. Once trapped, the live prey gets dumped into the oral opening for consumption. The video clearly shows this unique way of hunting for food.

young M. viridis

Worldwide, there are about 17 valid species of Melibe. Like other nudibranchs, Melibe are hermaphrodites. M. viridis grows up to 13 centimeters. Its color varies widely from light to dark, depending on the coloration of the substrate.

Only lucky divers will ever see a Melibe viridis searching for prey. However, for your chance to see one in Gorontalo, please book your dive trip with us.

Dive Season in Gorontalo

Dive Season in Gorontalo runs from November to April. During this time, seas are typically calm and blue. Light afternoon showers make for enjoyable, balmy nights.

Surprising Discovery

Before Miguel’s Diving opened diving in Gorontalo in 2003, no one knew the dive season here. In fact, no others were diving in Gorontalo prior to that. The common assumption was that the dive season in Gorontalo would be the same as its nearest neighbors, Bunaken National Park in Manado and the Togean Islands. The distance to Manado is about 400 km. The ferry trip to the nearby Togeans lasts one night.

Contrary to conventional wisdom, diving season in Gorontalo is quite different. Its discovery marked the conclusion of two years’ survey work conducted by Miguel’s Diving staff.

Wind Direction not Rain

Conventional wisdom also says that off season for diving should be during rainy season. And, that dive season should be during dry season. In Gorontalo’s case, the opposite is true. The key factor is wind direction not precipitation.

dive season
Surface interval during dive season

When the northwest monsoons descend on Southeast Asia, Sulawesi Island is affected. The winds that bring rain hit two lines of mountains before they reach the sites where Miguel’s Diving takes guests. As a result, the seas along Gorontalo’s southern shoreline are calm. Rain rarely hits the entire area. The usual time for showers is three o’clock in the afternoon when rising temperatures gather moisture. Gorontalo City on average receives half the annual rainfall as Manado, which faces north and into the rains.

However, when the dry winds from Australia hit Sulawesi, Gorontalo’s southern coastline is exposed. Seas adjacent to Miguel’s Diving dive sites plunge to over four kilometers. With no islands or barrier reefs, the coast is hit by wind-driven waves. Three to five meter waves are typical during dry season.

Dive Season in Gorontalo

Officially, dive season here runs from November to April. Miguel’s Diving opens for regular diving after the moon change in October. Regular diving ends by mid-May. After that, diving twice in the early morning can be possible. Oftentimes, seas are too rough to use speed boats. The worst sea conditions occur in August. At that time, perhaps only one dive is possible. Sites are limited to only one or two locations by beach entry.

Gorontalo’s dive sites are located in Tomini Bay. This large bay is split by the equator. Perhaps because of the closeness to the equator, Miguel’s Diving staff have observed the change in wind direction has not varied more than two weeks during the two decades of observation.

As a result, we recommend making a booking with us during regular diving season.
