Pick a month: the diving season, from published sources, and the typical weather.
Pick a month
The warmest water of the year.
Typical weather, not a forecast: averages for 2021–2025 (air, rain, wind) and 2023–2025 (sea), data from Open-Meteo (ERA5 / Copernicus, Météo-France). Covers an area of roughly 10 to 25 km around the destination.
Months follow PADI, except September, which is shown as good rather than best: it is the peak of hurricane season. PADI: no bad time, ~300 diveable days, May–Sep calm. Jan–Feb have the best visibility and peak eagle rays, but occasional norte winds.
From the easiest to the most demanding. Levels with a dashed outline are estimates we are still verifying.
