Frequently Asked Questions

Malpelo and Cocos have two (2) main seasons:
Dry season - starts 15 December to 1 May; prevailing winds and swell come from the north, producing an upwelling that brings cold water up and a lot of plankton that can affect visibility, but brings in a lot of fish and sharks.
Rainy (or wet) season - lasts from May through beginning of December, with prevailing winds coming from the southwest.
During the wet season it rains for 2-3 hours in the afternoon, while it’s cloudy/sunny the rest of the day. We experience heavier and more frequent rains in October-November, and occasionally it rains all day long.

Malpelo and Cocos are wild places and are convergence points for 8 major sea currents, so the conditions are quite unpredictable, with March-April being relatively calm. Fortunately, up until this moment we never had to cancel an expedition due to bad weather.

Below is some information on the average conditions in the area:

Surface temperature27-28 C / 81-82 F26-28 C / 79-82 F
Water temperature20-24 C / 68-75 F16-20 C / 61-68 F
Thermocline25-30 meters / 82-98 feet or sometimes nothing15-25 meters / 49-82 feet
In the Pacific, an ocean full of nutrients and currents, visibility can change in a very short time.
Coiba: 5-35 meters / 16-115 feet
Malpelo: 10-35 meters / 33-115 feet
Cocos: 5-35 meters / 16-115 feet
Coiba: 5-35 meters / 16-115 feet
Malpelo: 10-35 meters / 33-115 feet (occasionally there can be upwellings full of plankton that bring a lot of fish but at the same time reduce visibility)
Cocos: 5-35 meters / 16-115 feet

COIBA is a diverse destination for those who want to interact with nature. The conditions are favorable in Coiba year round, though whale watchers may want to come for a visit when the whales arrive for their annual migration in June through beginning of November.

You can see big schools of jacks, snappers, barracudas, groups of all kinds of rays – eagle, devil, cow-nosed, manta (frequent) – frogfish, seahorses, a diversity of corals, as well as the almost-extinct black coral. Whale sharks are seen here often along with white-tip sharks, bull sharks, and hammerhead sharks.

MALPELO is renowned for the huge concentration of sharks that can be seen at one time and the variety of species that can be found in the area, from the most frequently seen to the rarer varieties—hammerhead, Galapagos, silky, whale, white-tip, black-tip, dusky, and small toothed sand tiger sharks.

Sharks are abundant all year; however, there are greater chances of seeing some species at certain times of the year:
December-April – large schools of hammerheads; hammerhead sharks can be seen all year round, but scientists have observed that the schools are bigger during these months.
December-April – small toothed sand tiger shark, which is a very rare pelagic sand tiger shark that nowhere else in the world can be seen; in the dry season we have the chance to see it in colder and deeper (35-55 meters / 115-180 feet) waters. Note: this dive is for experienced divers only.
May-August – schooling silky sharks of up to 1,000 individuals
June-September – whale sharks; like the hammerheads, whale sharks can be seen throughout the year, but the chances of seeing them are greater during this period.
July-October – humpback whales
November – schools of hammerheads of up to 200 individuals

The other year-round star attractions in Malpelo are the free swimming moray eels, the big schools of jacks, snappers, and leather bass, the barracudas, the groups of eagle rays, and the yellowfin tuna.

COCOS is best known for schooling hammerhead sharks and being a magnet for large pelagic species. May to November are the months when the hammerhead sightings are more frequent and the schools are bigger; however, diving at Cocos is year-round. Galapagos sharks, groups of tiger sharks, white-tip sharks, and groups of marble rays are also commonly seen here.

Most diving days consist of two dives in the morning and one in the afternoon, with several night diving opportunities provided throughout each trip. Each of our dive vacations begins with the opportunity for one or two “check out dives,” providing you the opportunity to test your dive equipment, weighting and test your camera gear, along with providing an insight and orientation to the ocean conditions and marine environment of the rich waters of the Tropical Eastern Pacific.

We dive in groups of up to 9 divers plus a dive guide in each skiff; we practice the buddy system and we try to keep the group together in order to maximize our bottom time. On each dive our 2 twin-engine dive skiffs go to separate locations to ensure that the 2 groups never dive the same site at the same time. And, since only one boat is allowed at the island at a time in Malpelo, you are assured of ample space and better animal interactions on your dives.

Due to the characteristics of the diving in the Tropical Eastern Pacific Islands of Coiba, Cocos and Malpelo, new divers might find this diving environment challenging. An Advanced Open Water certification with at least 30 logged dives is mandatory in order to dive Malpelo and Cocos, while an Open Water certification is sufficient to dive Coiba. Non-divers and children are welcome to join our expeditions to Coiba National Park.

NOTE: You will need to show your certification card to our dive guide prior to diving. We strictly impose the NO CERTIFICATION, NO DIVING rule. We do not have an internet connection onboard, so we will not be able to do any online verifications for you. Please ensure that you have your card with you.

Some of our Malpelo and Cocos itineraries include a few days of diving in Coiba National Park. Aside from scuba diving and whale watching, the former prison colony’s lush greenery and white sandy beaches are ideal for kayaking, snorkeling, hiking, birding, and observing wildlife.

On each Coiba expedition from June to November scheduled in our itinerary, a whale watching guide will be on board. During these expeditions, divers and whale watchers share the boat.

Whale watching tours are posible from a minimum of 3 days to 7 days. You come and go with the regular schedule.
7-day Whale Watching Tour: pricing starts from USD 2,400
3- to 6-day Whale Watching Tour: USD 350 USD/day

Most Expeditions on M/V Yemaya are scheduled for 7 days. If you want to spend less days in Coiba, you have to come (or leave) with a special boat from Puerto Mutis or St. Catalina to arrive to Yemaya in Coiba. The 3-hour boat ride from the mainland to Coiba (or vice versa) costs USD 380/trip. The boat can accommodate up to 8 persons.

Included: Guided whale watching tours every day, land tours, kayak and snorkel equipment, diving, onboard cabin accommodation, 3 meals/day, snacks, and non-alcoholic beverages.

Most of the navigation around the Coiba region is fairly calm.

Our crossings to Malpelo and Cocos range from 25 to 32 hours, which include one overnight passage to the destination and another one going back to port. The crossings can be a little bumpy at times; however the diving in these remote islands makes it more than worthwhile.

M/V Yemaya is a sturdy seaworthy vessel. However, if you suffer from travel sickness, we highly recommend that you bring your own medication and take precautions prior to boarding.

Non-divers and children are welcome to participate in any of the non-diving activities that are available on our expeditions to Coiba National Park.

A passport is required and depending on your citizenship, you may need a visa or tourist card to enter the country. We recommend that you check with your local embassy prior to booking the trip.

The monetary unit is the Balboa, but the US dollar has been legal in Panama since 1903, with an exchange rate of 1:1.

At the moment, we only accept cash payments onboard. It is better to bring US dollars along or withdraw from ATM machines. Travelers checks are not common here and are not accepted in most places. In the few places where they are accepted, there is a high cost involved to exchange them. There are only a few exchange houses in Panama, and the rates are normally not favorable.

We strongly recommend that all our guests purchase some form of dive and personal medical insurance.

Panama City has several modern, high quality medical facilities. The decompression chambers and hyperbaric doctors of the Panama Canal Authority are affiliated with Divers Alert Network.

Aboard M/V Yemaya, we have a current Emergency Assistance Plan and extensive medical supplies, medical oxygen and trained personnel who can deliver basic life support, first aid and medical oxygen. For more information, please see our safe diving practices or visit the M/V Yemaya page.
