Humpback Whale Costa Rica July – Encounter Guide & Best Sites

Southern Hemisphere humpbacks (breeding population) arrive in Costa Rica’s Pacific coast – one of only two countries to receive humpbacks from both hemispheres.

Encounter overview

Diving or snorkelling with humpback whales in Costa Rica during July is high season, with an encounter probability of approximately 80% under normal conditions. Humpback whales are the ocean’s showmen – breaching, tail-slapping, and singing in frequencies that travel hundreds of kilometres. In-water encounters are among the most profound experiences in ocean travel.

Best sites

What to expect

Humpbacks migrate between polar feeding grounds and tropical breeding/calving areas. Singing males are stationary for minutes at a time – a gift for in-water encounters. Mothers with calves are highly protective; maintain distance and wait for the whale to approach.

Water conditions in July

Water temperature in Costa Rica typically ranges 22-29°C. Visibility at Drake Bay in July 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

In-water encounters require a licensed operator and often a permit. Do not enter the water if the whale is actively fleeing. Fins and masks only – scuba bubbles disturb whales. The whales often approach curious, stationary humans on their own terms.
