Winter and spring: bring layers and wait for the warmth
December, January and February have daytime averages of 13°C, so plan for a jacket rather than beachwear. January and February nights fall to 5°C, making warm evening layers important. March lifts to 16°C, but the sea stays at 13°C; brighter spells do not make it a swimming month for most travellers. April is milder at 18°C, though it averages 10 rain days, so keep outdoor plans flexible. May is the better spring compromise: days reach 22°C and there is more sunshine, but the sea is still a cool 16°C. Pack lighter clothes for daytime alongside a jumper and waterproof. Spring suits travellers who want comfortable outdoor weather more than long swims.
Summer: the best balance of sunshine and swimming
June brings daytime averages of 26°C and a sea temperature of 20°C, making it a sensible choice if you want warmth without the strongest summer heat. July and August both average 29°C by day and 20°C at night, so light clothing works well, with shade breaks around midday. July has the most sunshine, averaging 10 hours daily, and fewer rain days than August. August has the warmest sea at 24°C, which may matter more if swimming is your priority. Neither month is rain-free, so leave room to adjust your plans. Choose June for gentler heat, July for sunshine, or August for warmer water.
Autumn: warm water first, cooler evenings later
September is a good alternative to peak summer if you still want warm days and swimmable water: daytime averages are 25°C and the sea holds at 23°C. The catch is rain, with 11 rain days on average, so it is less suited to rigid outdoor plans. October remains mild at 21°C, with the sea at 20°C, but it is the wettest month overall. A waterproof and an evening layer earn their place in your bag. By November, days average 16°C and nights 9°C, shifting the emphasis towards time outdoors in warmer spells rather than beach days. For an autumn swimming holiday, September is the clearest choice.
