Winter and spring: comfortable for walking, cool for swimming

From December to February, plan around mild afternoons rather than reliable beach weather. December and February average 15°C by day, while January is cooler at 14°C. Nights fall to 8°C in January and February, so bring a jacket and layers for evenings. March reaches 17°C, but the sea remains at 14°C: sunshine does not yet mean comfortable swimming for most travellers. April's 19°C days make time outdoors more appealing, although a 16°C sea still feels cool. May is the stronger choice for warmth without summer heat, with daytime temperatures of 22°C and evenings around 15°C. Its 18°C sea may suit a brief dip if you tolerate cool water, but June is a better bet if swimming is central to your holiday.

Summer: the strongest choice for sun and sea

June offers a useful balance: days average 26°C, nights 19°C and the sea 22°C, with little rain to interrupt outdoor plans. July turns up the heat to 29°C and brings 12 hours of sunshine a day, making shade and a slower pace around midday sensible. It is also the driest month, averaging just 1 rain day. August has similar daytime and night-time temperatures, but the sea reaches 26°C, its warmest monthly average. Both July and August suit travellers who want warm-water swimming and evenings that rarely call for much extra clothing. The catch is the heat: choose June if you prefer gentler conditions, and keep longer walks to the cooler parts of the day.

Autumn: warm water, but less dependable dry weather

September remains a good swimming option, with daytime temperatures of 26°C and a sea averaging 25°C. The trade-off is rain: it is the wettest month overall, so leave room to rearrange outdoor plans. October eases to 22°C by day, matching the sea temperature, while nights average 17°C. That makes it appealing if you dislike peak-summer heat, though its 8 rain days mean dry weather is less dependable. November is a clearer step towards winter, with 18°C afternoons and 12°C nights. The sea still averages 19°C, but swimming becomes more a matter of personal tolerance. Pack layers and a light waterproof for autumn rather than relying entirely on summer clothing.
