Winter and spring: mild days, cool water

December is mild rather than warm, averaging 15°C by day, before January and February settle at 14°C. Nights call for layers, and regular rain makes a waterproof useful throughout winter. This suits travellers happy to spend time outdoors between showers, rather than those planning to swim. March brings a modest lift to 16°C, but the sea remains cold at 14°C. April feels more comfortable for unhurried days outside, with daytime averages of 19°C, though evenings still need a jacket. May is the better compromise for warmth without summer heat: days reach 22°C and sunshine increases. The catch is the sea, averaging 18°C, so pleasant weather on land does not yet mean a comfortably warm swim.

Summer: the strongest choice for beach weather

June offers summer warmth without the highest daytime temperatures, averaging 26°C with a sea temperature of 22°C. It is a good fit if you want swimming weather but find hotter afternoons tiring. July is the driest month and has the most sunshine, averaging 12 hours daily, so shade and sun protection deserve a place in your plans. August is hottest, with daytime averages around 30°C and nights at 23°C. Choose light clothing and keep more active outings away from midday. The sea reaches 26°C in August, making this the strongest choice for travellers who value warm water and do not mind the heat.

Autumn: warm water, but more changeable plans

September retains much of summer's warmth, with days averaging 26°C and the sea at 25°C. The trade-off is rain: it averages 7 rainy days, so leave room to rearrange outdoor plans. October still suits travellers looking for warmth rather than strong heat, with both daytime and sea temperatures averaging 23°C. Swimming remains an option if those temperatures suit you, but shorter sunshine hours and more frequent rain make it less dependable for a beach-focused stay. November brings a clearer shift towards cooler weather. Days average 18°C and nights 14°C, so pack layers and a waterproof rather than relying on summer clothes.
