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.
Diveable year-round. Dec–Apr is the stated peak season (calm seas, lighter winds, best visibility). May–Nov is off-peak with warmer water but lies in the Atlantic hurricane season (1 Jun–30 Nov); it is shown as good rather than possible since sources describe it as quieter, with fewer crowds, not closed.
