Peak whale shark aggregations (100+ individuals) as Rufiji River plankton blooms peak; warm 81–84°F water, though visibility is reduced by nutrients.
Best overall diving: whale sharks still present, warmest water (~84°F), best visibility in Chole Bay, calm seas, and 50+ coral genera on the reef.
Dry-season diving limited to sheltered Chole Bay due to SE trade winds; clearest visibility of the year, cooler 77°F water, good for reef fish density.
Boat/panga-access dives across Chole Bay, Kinasi Pass, Forbes Reef, and the outer barrier reef deliver whale sharks, hawksbill turtles, reef sharks, and dense coral in 77–84°F water with 25–30 m (82–98 ft) visibility; welcoming to novice and advanced divers alike.
