Winter and spring: layers first, swimming later
December, January and February suit travellers who do not need beach weather. Daytime averages sit between 10°C and 12°C, and nights are cold enough for a proper jacket. December is particularly rain-prone, so keep outdoor plans flexible and pack waterproofs. March brings a lift to 14°C by day, but the sea remains chilly. April is more comfortable for spending time outside at 16°C, though its 11 rainy days mean showers still need a place in your plans. May is the clearer turning point: days average 21°C and rain becomes less frequent. It is a good choice if you dislike summer heat, but the 19°C sea may still feel bracing. Bring a layer for evenings rather than packing only summer clothes.
Summer: the strongest choice for sea and sunshine
June offers warm days without quite the same heat as July and August. With a 22°C sea and 5 rainy days on average, it suits a holiday built around swimming and time outside. July and August are hotter and drier, both averaging 28°C by day and 3 rainy days. Plan more active outings for the morning and leave room for shade around midday. July has the most sunshine, while August has the warmest sea at 26°C. Nights stay warm too, particularly in August, so light clothing is useful well beyond the afternoon. These are the strongest months if reliable warmth matters more than avoiding heat.
Autumn: September keeps the sea warmth
September is the autumn month to choose for swimming without peak summer heat. Both the daytime air and sea average 24°C, although rain is more frequent than in summer. October can still work for travellers happy to mix outdoor time with weather-dependent swims: days average 20°C and the sea 21°C. The catch is its 10 rainy days, so do not rely on an uninterrupted run of dry weather. November is a different proposition, with daytime temperatures falling to 15°C and rain on 14 days. Pack layers and waterproofs, and choose it for cooler-weather relaxation rather than a holiday centred on the sea.
