Warm days without consistently intense heat

June suits travellers who want warmth but would rather avoid regularly very hot afternoons. Days reach 25°C on 36% of occasions, while 30°C is much less common, at 2%. That makes walking around a reasonable plan, though shifting longer outings towards morning or later afternoon should feel more comfortable. Humidity averages 77%, so loose, breathable clothes are a better choice than anything heavy or close-fitting. Pack sun protection and leave room for breaks out of direct sunshine. Evenings generally remain warm enough for light clothing, but a thin layer is sensible if you tend to feel cool: the coldest 10% of nights fall to 18.3°C or below.

Dry weather and a sea ready for swimming

Rain is unlikely to shape your plans: June averages about 0 rainy days and just 2.0 mm of rainfall. That is a strong case for keeping most of your time outdoors, rather than building the trip around wet-weather alternatives. Sunshine averages about 12.2 hours within 14.4 hours of daylight, giving you plenty of flexibility to take a midday break and head out again later. Swimming is a reasonable part of the plan too. The sea averages 22.2°C, with a year-to-year range of 21°C to 23°C. It should suit many swimmers, though those who prefer very warm water may find the initial dip cool. Bring swimwear, but do not expect bath-like warmth.
