Pick a month
Exposure suit: 7 mm full suit or 8/7 mm semi-dry · if you feel the cold: 8/7 mm semi-dry or drysuit. How we choose
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.
Diving is year-round; PADI names Sep–Nov as ideal. Dec–May is colder but the kelp thrives and seals, sea lions and gray whales are seen more often; Jun–Aug may bring plankton blooms that reduce visibility. Winter storms can temporarily close exposed sites, while sheltered sites like the Breakwater are dived almost every day.
From the easiest to the most demanding. Levels with a dashed outline are estimates we are still verifying.
