Winter and spring: better for time outdoors than swimming

December to February suits travellers who want mild daytime weather rather than a beach-focused holiday. January and February average 14°C by day, but February nights fall to 9°C, so bring a jacket and layers rather than relying on light holiday clothes. Rain is a regular possibility, making flexible outdoor plans useful. March starts to feel milder at 16°C, although the sea remains cool. April reaches 18°C, comfortable for being out and about without summer heat, but evenings still need an extra layer. May offers the clearest move towards warmer holiday weather: days average 21°C with 8 hours of sunshine. The catch is the sea at 18°C, which may still feel chilly for a leisurely swim.

Summer: the strongest choice for beach weather

June offers a useful balance if you want summer warmth without the highest temperatures. Days average 25°C, nights 19°C and the sea 22°C, so swimming becomes more appealing while evenings stay relatively comfortable. July is the driest month, averaging 1 rain day, and its 12 hours of sunshine favour long days outdoors. August is hotter, with daytime temperatures around 29°C and nights at 23°C; accommodation where you can keep cool matters if warm nights disturb your sleep. Its sea temperature of 26°C is the warmest of the year. Across summer, pack light clothing and sun protection, and take a break from direct sun around midday.

Autumn: warm seas, but less dependable dry weather

September is a good choice if swimming matters more than the driest possible weather. The sea stays at 25°C and days average 26°C, but rain days rise to 7, so leave room to rearrange outdoor plans. October still has useful warmth, with both daytime and sea temperatures averaging 22°C. It suits travellers happy to mix swimming with other outdoor time rather than expect uninterrupted beach weather. Bring a light layer for evenings and something waterproof. November feels more like a mild-weather break: days average 18°C and nights 14°C. The sea retains some warmth at 19°C, but cooler air and wetter conditions make it less appealing for lingering after a swim.
