January to May: mild winter gives way to outdoor warmth

January and February both average 14°C by day, so pack layers and a waterproof rather than relying on beach clothes. January has more rain days, while February's sea is slightly cooler. March brings a modest lift to 16°C and less frequent rain, but evenings still call for a jacket. April feels more promising for time outdoors, with 19°C days and longer sunshine, although the sea remains at 17°C. May is the clearer turning point: days reach 23°C, nights average 18°C and rain becomes uncommon. It suits travellers who prefer walking and sitting outside without summer heat, though the 20°C sea may still feel brisk when you first get in.

June to August: the strongest beach weather, with hotter nights

June offers a useful balance for a beach holiday: days average 27°C, the sea reaches 23°C and sunshine is plentiful. July and August bring the highest daytime heat, both around 30°C, so plan more active time for mornings and leave room for shade at midday. July has the most sunshine, while August has the warmest sea at 27°C. Evenings offer limited cooling, particularly in August when nights average 25°C; light clothing and somewhere comfortable to sleep matter. Rain days average 0 throughout these months, making this the strongest stretch for outdoor plans, though that average should not be read as a guarantee of dry weather.

September to December: warm seas linger as rain returns

September keeps much of summer's appeal, with 28°C days, a 26°C sea and little rain. It is a strong choice if swimming matters but you would rather avoid the highest summer heat. October remains warm enough for beach time on suitable days: both air and sea average 24°C, although rain is more likely and sunshine is reduced. November's 22°C sea holds warmth better than its 20°C daytime air, so getting out of the water may feel cooler than being in it. By December, days average 16°C and rain days rise to 12. Pack a waterproof and warmer evening layers, and keep outdoor plans flexible rather than expecting a reliably sunny beach break.
