Spring: comfortable days before the sea warms up

March is better suited to time outdoors in layers than a swimming holiday: days average 14°C, nights 10°C, and rain remains fairly frequent. April brings a modest improvement, with daytime averages of 16°C, but the sea is also just 16°C, so do not expect warm water. May is the more appealing spring choice for travellers who dislike summer heat. Days reach 20°C on average, with 8 hours of sunshine and fewer rainy days than earlier in spring. Pack a light layer for evenings and something waterproof. The main compromise is swimming: May's 19°C sea will still feel cool, especially when you first get in.

Summer into September: choose dry days or warmer water

June gives you warm days without the highest summer averages, alongside 11 hours of sunshine and just 4 rain days. Its 22°C sea is warming up, though July and August are better choices if swimming is your priority. July has the most sunshine and the fewest rainy days, while August has the warmest sea at 25°C. Plan shade breaks around midday and pack light clothing: nights average 22°C in July and 23°C in August. September is a useful compromise if you want less daytime warmth without losing the warm water. Both air and sea average 24°C, but 8 rain days mean you should leave room for changes of plan.

Autumn and winter: mild spells, but plan around rain

October still offers relatively mild days at 20°C and a sea averaging 22°C, so swimming remains an option if you are comfortable with cooler conditions afterwards. The catch is 10 rain days and less sunshine than summer. November turns cooler and wetter, making it a weaker choice for a weather-led holiday, despite a sea that retains some warmth. December's 13°C daytime average falls to 12°C in January and February, with nights cool enough for a proper jacket. January and February have similar temperatures and rain frequency, although February offers slightly more sunshine. Winter suits travellers happy with cool outdoor time and flexible plans, rather than those expecting beach weather. Bring waterproofs and layers throughout this period.
