Spring: improving sunshine, but a cool sea

March is still more suited to walks than lounging in swimwear, with daytime averages of 15°C and rain frequent enough to keep a waterproof handy. April brings a clearer improvement: days reach 17°C, sunshine increases and wet days become less frequent. Pack layers rather than relying on summer clothes, particularly for evenings. May is the stronger choice for comfortably warm days outdoors, averaging 21°C with relatively little rain. The catch is the water: even in May, the sea averages 19°C, so it may feel brisk if you like a leisurely swim. Choose late spring for warmth without the midsummer heat, rather than for reliably warm water.

Summer: the strongest choice for sun and swimming

June offers the gentlest summer balance, with days averaging 25°C and the sea reaching 22°C. It suits travellers who want swimming weather without the warmer nights of late summer. July is the driest month and has the most sunshine, so shade breaks and sun protection should shape your midday plans. August is marginally the hottest month, though both July and August round to 28°C by day. August also has the warmest sea at 26°C, making it especially suitable if swimming is your priority. The catch is overnight warmth: August nights average 25°C, so consider how comfortably you sleep in heat when choosing accommodation.

Autumn and winter: lingering warmth, then wetter weather

September keeps much of summer's warmth, with days at 26°C and sea water at 25°C, but rain is a more regular interruption. October remains mild at 22°C by day, and its 23°C sea can still suit swimming when conditions allow; keep plans flexible rather than expecting uninterrupted sunshine. November shifts towards wetter-weather travel: days average 18°C, and it is the wettest month. December is cooler again at 15°C, with frequent rain making a waterproof more useful than beach kit. January and February both average 14°C by day and 11°C at night, so bring layers for evenings as well as daytime outings. Winter suits travellers content with mild spells between showers, not those whose holiday depends on sunbathing or comfortable sea swimming.
