Climate and temperatures in Corsica

Corsica enjoys one of the most generous Mediterranean climates in Europe, with over 2,700 hours of sunshine a year, warm seas from June onwards, and landscapes that change with the seasons. But depending on what you want to do - beach, hiking, authentic village or high-altitude skiing - the right time won't be the same.
A quick summary:

🏖️ Swimming & beach: June to September (water between 21°C and 25°C)
🥾 Hiking & nature: May, June, September, October
🏔️ Mountains & skiing: December to March
💐 Corsica without crowds: April-May or October

July-August is the sunniest month (85% clear skies) but also the most crowded. September remains the ideal month for many: sea still warm at 23°C, crowds in retreat, golden light.
