Costa Rica Activities
Scuba Diving and Snorkeling
When is the best time to snorkel or scuba dive in Costa Rica? The best time of year for snorkeling or scuba diving in Costa Rica is during the dry season. This is when visibility is best because runoff from countless rivers flowing into the oceans isn’t burdened with excess mud and debris, affecting water clarity along the shoreline.
Nonetheless, enjoying Costa Rica’s underwater world can be enjoyed year-round if you choose your days and diving/snorkeling sites right. Try to hit the waters at least 24 hours after the last rains or take a tour to an offshore location that’s less affected by river runoff.
Costa Rica dry season for the Pacific Coast: December through April with a slight let-up in rains in late July.
Costa Rica dry season for the Atlantic Coast (Caribbean Ocean): September and October with a slight drop in the heavy rains in January and February.
