Spinner dolphins (Stenella longirostris) rest inshore in the morning and feed offshore at night. Common dolphins hunt cooperatively in open water. Bottlenose dolphins are resident at many sites and well-habituated to human presence.

Water temperature in Costa Rica typically ranges 22-29°C. Visibility at Caño Island in August is generally good; check local liveaboard or dive operator reports the week of your trip for specific conditions. Pelagic liveaboard, cocos island is the primary dive style in Costa Rica.

Practical tips

Let the dolphins approach you – swimming toward them usually results in them leaving. A surface snorkel is less intrusive than scuba. Avoid isolated mothers with calves. Never feed wild dolphins.
