December to March: warmer water, more frequent rain
December starts the warmer, wetter stretch, with daytime averages of 28°C and sea temperatures of 27°C. January, February and March keep that daytime warmth, while the sea reaches 28°C and nights stay at 25°C. This period suits travellers who value warm swimming water and do not mind adjusting outdoor plans around rain. The trade-off is substantial: January averages 25 rain days, easing to 23 in March, with 5 hours of sunshine throughout that stretch. Keep plans flexible rather than relying on uninterrupted sunny days. Light clothing makes sense even after dark, and a waterproof layer is more useful than packing for chilly evenings.
April to June: easing heat and a shift towards drier weather
April is a transition rather than a clean break from the wetter weather: days average 27°C, but there are still 20 rain days. May offers a more comfortable compromise if you want warmth in and out of the water, with both daytime and sea temperatures averaging 26°C. By June, days ease to 24°C and rain days fall to 11, making it a strong choice for travellers who dislike intense warmth. The sea remains at 25°C, warmer than in the following months. Evenings also cool through this period, so bring a light layer for sitting outside rather than assuming the warmth will last unchanged after sunset.
July to November: mild days, then a warmer spring
July and August suit travellers who prefer mild days, though they are less convincing for a holiday centred on warmer swimming water: both air and sea average 24°C. Nights fall to 20°C, so a light evening layer is sensible. September keeps those temperatures but sunshine rises to 7 hours, making it a better balance for time outdoors. October adds warmer days at 26°C and averages 11 rain days, although the sea stays at 24°C. November then lifts daytime warmth to 27°C and sea temperatures to 25°C, with a modest increase in rain days. Choose September or October for sunshine without the wetter summer pattern.
