Season by season
May–Aug
The calmest, warmest stretch — water up toward 29°C.
Aug–Oct
Rainy season. Showers come in the afternoon and clear quickly; the diving is unaffected.
Nov–Feb
Around 26°C, and the season for eagle rays. Northerly winds can move us to sheltered sites.
Mar–Apr
Quiet, and a sweet spot between the two.
Wetsuit. A 3 mm full suit suits most divers year-round. Bring a 5 mm or an extra layer for winter, or if you feel the cold on repetitive days.
