Spring: comfortable days, but the sea takes longer to warm
March brings daytime averages of 18°C, making it more suitable for walking than lying by the sea. April reaches 20°C, though both months average 7 rain days, so keep a light waterproof handy rather than planning every day around sunshine. May is the stronger choice for warmth without midsummer heat: afternoons average 24°C, rain drops to 4 days and sunshine reaches 9 hours daily. The catch is the water, which averages just 18°C even in May. Choose spring if you enjoy being outdoors but do not need long swims. Pack layers for evenings, with May nights still averaging 16°C.
Summer: the strongest choice for sunshine and swimming
June offers a useful balance: daytime averages of 28°C, sea temperatures of 22°C and just 2 rain days make beach plans easier without the higher heat of late summer. July and August both average 31°C by day, so leave energetic outings for the morning and take shade at midday. July has the most sunshine, averaging 13 hours daily, and rain is rare rather than something to plan around. August has warmer water at 27°C, which suits travellers who find early summer swimming too cool. Nights stay warm too, averaging 22°C in July and 23°C in August, so lightweight clothing is more useful than heavy evening layers.
Autumn and winter: lingering sea warmth, then cooler days
September still feels summery at 28°C by day, with a 26°C sea, but its 6 rain days make flexible plans sensible. October offers a different balance: air and water both average 24°C, although it is the wettest month. November drops to 20°C by day while the sea holds at 21°C, so swimming depends more on your tolerance for cooler conditions. December is noticeably cooler at 16°C, and January and February average 15°C. These months suit travellers content with mild afternoons rather than dependable beach weather. Bring a jumper and a light waterproof: winter months average 7 rain days each, and February nights fall to 9°C. With the sea cooling to 15°C in February, winter is not the obvious choice for comfortable swimming.
