Winter into spring: layers first, swimming later

December, January and February are the least suitable months for a holiday built around sunshine. January and February average 12°C by day and 4°C at night, so bring a proper evening layer rather than just summer clothes. December and January each average 11 rain days; keep outdoor plans flexible and pack waterproofs. March lifts to 15°C, but the sea remains cool at 17°C. April is more comfortable for daytime outings at 18°C, though its 8 rain days mean showers still need a place in your plans. May is the stronger choice for warmth without peak summer heat: days average 22°C with 10 hours of sunshine. The catch is a 20°C sea, which may feel brisk, and evenings that still call for a jumper.

Summer: reliable sunshine, with a midday heat trade-off

June brings a clear shift towards summer conditions, with 27°C days, a 24°C sea and 3 rain days on average. It suits travellers who want warm swimming water but prefer less heat than in high summer. July and August are the driest stretch, each averaging 1 rain day, so rain is less likely to disrupt outdoor plans. July reaches 30°C by day, while August is the hottest month at 31°C and has the warmest sea at 28°C. Plan more active time for mornings or later in the day, and leave room for shade at midday. Nights average 20°C in both months, so lightweight clothing makes sense after sunset too.

Autumn: warm water lasts longer than the summer heat

September keeps much of summer's appeal while easing the daytime heat. With 27°C days, a 27°C sea and just 2 rain days on average, it is a strong choice for swimming and spending long stretches outdoors. October is gentler at 23°C, while the sea stays warmer than in May at 24°C. That makes it appealing if swimming matters but intense heat does not; the trade-off is 5 rain days and cooler evenings at 13°C. November is a more cautious choice for a beach-focused trip. The sea still averages 22°C, but daytime temperatures fall to 18°C and rain becomes more frequent. Pack layers and allow plans to change with the weather.
