What water temperature is it like throughout the year diving in San Bernardo Archipelago, Colombia?
The water temperature in the San Bernardo Archipelago, Colombia, is consistently warm and tropical year-round. Divers can expect temperatures to range from 26°C to 29°C (79°F to 84°F).

The warmest water is typically found between June and October, but the difference is minimal.
When is the best time to visit San Bernardo Archipelago, Colombia?
The best time for diving in the San Bernardo Archipelago, Colombia, is during the dry season, from December to April. This period generally offers the calmest sea conditions and the best underwater visibility. While it's the windiest time of year (especially Dec-Feb), this primarily affects surface conditions.

What's the visibility like during the dive season in San Bernardo Archipelago, Colombia?
During the prime dive season (December-April), underwater visibility in the San Bernardo Archipelago, Colombia, is generally excellent, often ranging from 20 to 30 meters (65-100 feet). Outside of this season, during rainier or windier periods, it can occasionally decrease to around 10 to 15 meters (30-50 feet). However, because the islands are located far from mainland river runoff, the visibility remains consistently good for diving throughout most of the year.
Are there any seasonal migrations or special events (e.g., manta rays, whale sharks) in San Bernardo Archipelago, Colombia?
The San Bernardo Archipelago, Colombia, is not known for large, predictable migrations of megafauna like whale sharks or manta rays. The primary attraction is the rich, resident marine life and healthy coral reefs, which are fantastic year-round. However, you may encounter sea turtles, as several species inhabit and nest in the region. The lack of major migratory events is offset by the consistent abundance of reef fish, sharks, and vibrant invertebrates on every dive.
What marine life can I expect to see in San Bernardo Archipelago, Colombia?
In the San Bernardo Archipelago, Colombia, you'll see a fantastic display of Caribbean reef life. Expect to find abundant hard and soft corals, large sponges, and colorful sea fans. Common sightings include angelfish, parrotfish, moray eels, lobsters, pufferfish, and schools of blue tangs and sergeant majors. It's also possible to spot southern stingrays, nurse sharks resting under ledges, and the occasional eagle ray gliding by. The biodiversity within the protected national park is its main draw.
What thickness wetsuit should I wear in San Bernardo Archipelago, Colombia?
Given the warm water temperatures of 26-29°C (79-84°F) in the San Bernardo Archipelago, Colombia, a full wetsuit is not necessary for most divers.
