Spring: mild days, but a cool sea
March brings daytime averages of 18°C, rising to 19°C in April and 22°C in May. That makes spring a good fit for walking and spending time outside without summer heat, although March averages 8 rain days, so keep plans flexible. April still calls for layers, especially once the sun goes down. May feels warmer, with 8 hours of sunshine and nights averaging 15°C, but a light jumper remains useful for evenings. The catch is the water: sea temperatures move from 15°C in March to 17°C in May. Choose this season for comfortable days outdoors rather than expecting a warm swim.
Summer into September: warmth with a swimming trade-off
June offers a useful balance: days average 26°C, with 11 hours of sunshine and just 2 rain days, though the sea is still a fresh 19°C. July and August bring daytime averages of 29°C, making shade and a slower pace sensible around midday. July averages 13 hours of sunshine and 0 rain days, but that is not a promise of uninterrupted dry weather. August has warmer water at 21°C and nights averaging 20°C, so light clothing works well into the evening. September keeps the sea at 21°C while daytime temperatures ease to 26°C. Its 4 rain days mean a little more flexibility, but it suits travellers who want swimming weather without the highest daytime averages.
Autumn and winter: keep outdoor plans flexible
October still averages 22°C by day and 20°C in the sea, making it a reasonable choice for warmth if you can accept showers: it averages 8 rain days. November drops to 18°C by day, so lighter clothes need a warmer layer alongside them. December and February both average 16°C, while January is coolest at 15°C with nights of 9°C. These months suit travellers content with mild daytime weather rather than beach heat. Pack a jacket and rain protection, and use the brighter spells for outdoor plans. Winter sunshine averages 5 hours in December and January, increasing to 6 in February, but the sea remains chilly.
