on average

Typical weather, not a forecast: averages for 2021–2025 (air, rain, wind), data from Open-Meteo (ERA5 / Copernicus, Météo-France). Covers an area of roughly 10 to 25 km around the destination.

Diving runs year-round. Atlantis Divers (local operator) names March–July as the best time (calm seas on both sides of the island), August/September as the windy period with rougher sea and lower visibility, and late December–January as rough on the Mar de Dentro side (dives continue on the Mar de Fora side). PADI and a Brazilian travel blog say visibility is best in September–October; because the local operator flags September as windy, September is shown as good and October as best (when sources disagree we keep the more cautious reading). Nov–Feb is shown as good (no source calls them best; late Dec–Jan rough on the inner side).
