As of today, in season, building toward peak (~July 1). Earth Exhibit tracks the live conditions and flags it the moment it is on.
Adult bull sharks concentrate at cleaning-station reefs near San Pedrillo and the outer Bat Islands during the rainy season, forming predictable aggregations used by researchers and dive operators.
Aggregations are tied to seasonal oceanographic conditions and are a major ecotourism draw for Playas del Coco and nearby towns.
