Warm afternoons, with a cooler side after dark

June generally suits travellers who want summer warmth but would rather not have relentless heat. Days reach 25°C around 59% of the time, while 12% reach 30°C, so expect a mix rather than consistently hot afternoons. On hotter days, move more active plans away from midday and keep shade breaks in mind. Lightweight clothing should cover most daytime needs, with sun protection part of your usual routine. Evenings need a little more thought: the average low is 16.7°C, and the coldest 10% of nights reach 13.5°C or below. A jumper or light jacket is sensible if you plan to sit outside late.

Plenty of outdoor time, but a bracing sea

The main catch for a swimming holiday is the water. At an average of 20.3°C, the sea is bracing rather than comfortably warm; the year-to-year range of 19°C to 21°C means you should not count on bath-like conditions. It suits travellers happy with refreshing dips better than those who feel the cold quickly. Out of the water, around 8.5 hours of sunshine within 15 hours of daylight gives you plenty of scope to spread outdoor plans across the day. Rain is still part of the picture, with about 7 rainy days during June. Keep a light waterproof handy and make plans easy to rearrange rather than assuming every day will be dry.
