Winter and spring: mild days, cooler evenings
December brings daytime averages of 20°C, but it also has the most rain days, so leave room to change outdoor plans. January slips to 18°C and February reaches 19°C; both have nights around 14°C, making a jumper or light jacket useful after sunset. These months suit walking and sitting outdoors more than travellers seeking dependable heat. March and April both average 20°C by day, though April has slightly fewer rain days. May makes the clearest step towards summer, reaching 22°C with just 2 rain days and 9 hours of sunshine. It is a good compromise for time outdoors without peak summer warmth. The catch through spring is the sea: at 19°C in March and 20°C in April and May, it may still feel cool for leisurely swimming.
Summer: the driest weather and warmest evenings
June starts summer with daytime averages of 24°C, nights of 18°C and just 1 rain day. It suits travellers who want dry weather without the highest temperatures. July rises to 26°C and has the most sunshine, averaging 12 hours daily, while August is hottest at 27°C. Both months average 0 rain days, making them the strongest choices for plans that depend on being outdoors, though that is not a guarantee of unbroken dry weather. Keep more active outings for the cooler parts of the day and allow shade breaks around midday. Evenings stay warm, and the sea climbs from 21°C in June to 23°C in August.
Autumn: warm sea, but rain becomes more likely
September is the best autumn compromise: days average 25°C, the sea reaches 24°C and there are just 2 rain days. It suits travellers who put swimming high on their list but prefer less daytime heat than August. October keeps the same sea temperature, with days at 24°C and nights at 19°C, so warmth lasts beyond summer. The catch is an increase to 5 rain days, making flexible outdoor plans more useful. November remains mild at 22°C by day, but 6 rain days and 6 hours of sunshine make it less dependable for a sunshine-focused trip. Pack a light evening layer, as nights ease to 17°C.
