Warm days, with a cooler edge after dark

The warmth should suit travellers who find hotter summer weather tiring. Days reach 25°C around 26% of the time, while 30°C days account for just 2%, so do not plan around strong heat every afternoon. Light clothes are a sensible daytime choice, with sun protection and somewhere shaded to take a break at midday. Pack a jumper or light jacket for sitting outside after sunset: the colder nights can drop to 13.2°C or below. May works well if you want to spend time outdoors without making heat the main point of the trip. It is less suitable if reliably hot days and warm evenings are essential.

Plenty of sunshine, but a bracing sea

Around 8.7 hours of sunshine a day gives May a useful balance of sunny weather and time outdoors, though you should leave room for showers. There are about 4 rainy days, so a light waterproof is sensible rather than planning every day around indoor cover. Keep outdoor plans flexible instead of assuming the whole stay will be dry. The bigger catch for a beach-focused holiday is the water: at 18.5°C, the sea is bracing rather than comfortably warm. A sunny afternoon may feel inviting on land without making a long swim appealing. May therefore suits relaxing beside the sea better than a trip built around lengthy swims.
