Dive Conditions
Many Galapagos Dive sites, especially those in the northern Islands of Wolf and Darwin, are characterized by the presence of the following diving conditions: Currents, Surge, Thermoclines, Cold water.
The best time to dive in Galapagos highly depends on what you'd like to see. The diving season in Galapagos is generally divided into two categories: Whale Shark Season (June-November) and Manta Season (December-May) when it's slightly warmer. During the warmer Manta Season the schools of hammerheads are generally larger and giant manta rays may be found off Isabela island.
December - May: This is the warm season in the Galapagos with the highest water and air temps. Brief afternoon rain showers are common but expect the tropic sun to reappear after the rain. Water temperature is 70-86F (21-30C) with some cooler thermoclines at depth. The northern islands are generally colder. Visibility stays between 40-100 feet (12-33 meters).
June - November: This season is known as the guarua and is cooler with frequent mist and overcast days. Winds can create rougher seas at times. Water temperature is 60-75F (16-24C). While colder, the trade-off is the rich currents bringing nutrients into the islands, resulting in more abundant marine life. Visibility is slightly less as a result.
Galapagos diving conditions can be challenging. Currents are moderate to strong and may require you to grab hold of rocks below the surface so you don't drift away. Surges may create difficulties during your safety stops. The average visibility is 10 - 21m (30 - 70ft), but can be less.
June to December. However, September November is the best time to see the most wildlife, but the waters will be colder. The water for diving is cold all year-round, but even COLDER during this time of year, with thermoclines as well. Wetsuits of 7mm are recommended, as well as a hood and gloves.
Divers must follow their Dive Master and Galapagos Marine Reserve rules at all times. Divers must stick with the group and their Dive Master at all times, remain with their buddies, and ascend in pairs. Safety Stops are obligatory for all Galapagos dives.
