Spring: comfortable days, but a cool sea
March is still on the cool side for a beach holiday, with daytime temperatures of 15°C and a sea temperature of 16°C. Bring layers rather than relying on summer clothes. April feels milder at 18°C, and rain becomes less frequent, making it a better fit for spending time outdoors without much heat. May is the stronger spring choice for warmth: days average 21°C, with 10 hours of sunshine and just 3 rain days. The catch is the sea, which averages 19°C, so swimming may feel brisk even when the sunshine is pleasant. Keep a light layer handy for evenings throughout spring.
Summer: the best stretch for sunshine and swimming
June brings a clear step towards beach weather, with days averaging 24°C, nights at 22°C and a sea temperature of 22°C. It suits travellers who want warmth without choosing the hottest month. July reaches 26°C and has the most sunshine, averaging 14 hours daily, while August is warmer at 27°C and has the warmest sea at 25°C. Rain days average 0 throughout this stretch, so wet weather is much less of a planning concern, though that is not a guarantee. Plan shade breaks around midday and pack light clothing. July and August nights average 24°C, so evenings offer limited relief from the warmth.
Autumn and winter: lingering sea warmth, then wetter days
September keeps much of summer's appeal: days average 25°C, the sea stays at 24°C and rain averages 2 days. October is cooler at 22°C, but its 23°C sea makes it a useful option for swimming without peak summer warmth; allow more flexibility for showers. November shifts towards mild-weather travel, with 19°C days and 8 rain days, although the sea retains warmth at 21°C. December falls to 16°C by day, while January and February average 14°C. Rain is a regular consideration across winter, so pack a waterproof and layers for evenings. The sea cools from 19°C in December to 17°C in February. Choose this period for mild outdoor time between showers, rather than dependable beach weather.
