Winter and spring: layers first, lighter clothes by May

December to February is better for walking than lounging by the sea, provided you can work around showers. Daytime averages run from 16°C in December to 15°C in January and 14°C in February; nights call for a jacket. December averages 10 rain days, so keep outdoor plans flexible. March edges up to 16°C, but its 15°C sea still favours swimmers comfortable with cold water. April is a useful step towards drier weather, with 3 rain days and a daytime average of 17°C. May makes the strongest case for a mild-weather trip: days reach 20°C, nights average 17°C and rain falls on just 1 day on average. Pack light layers, but do not expect the 19°C sea to feel as warm as summer.

Summer: dependable warmth, with hotter afternoons and nights

June offers the gentler start to summer: days average 24°C and the sea reaches 22°C, making it a good compromise between walking and swimming. June and July both average 0 rain days, though that is not a promise of an entirely dry stay. July brings 27°C days, a 25°C sea and 14 hours of sunshine, so plan shade breaks rather than keeping every afternoon fully outdoors. August is hotter again at 28°C, with the sea at 27°C. The catch is the warmth after dark: nights average 23°C in July and 24°C in August. Light clothing and a room you can keep cool matter more than an evening jacket.

Autumn: warm seas linger as rain becomes more likely

September is the strongest autumn choice if swimming matters: both the daytime air and sea average 26°C, while nights remain warm at 23°C. The trade-off compared with summer is rain, averaging 4 days. October stays mild at 23°C by day, and its 24°C sea can make it more appealing for swimming than spring. However, 6 rain days and 6 hours of sunshine mean you should leave room to rearrange outdoor plans. November still averages 20°C by day, but rain rises to 9 days and nights ease to 17°C. It suits travellers who value mild temperatures more than reliably dry weather. Bring a light jacket and waterproof layer rather than packing only summer clothes.
