Warm days, with a layer for evenings

June suits travellers who prefer warmth to persistent heat. Days reach 25°C on 45% of occasions, while only 2% reach 30°C, so very hot conditions are possible but not typical. Light, breathable clothes are a sensible starting point, with sun protection and a break from direct sun at midday. Average night lows are around 18°C, comfortable for many people but cool enough to justify a light jumper when sitting outside. Cooler nights can fall to around 15°C or below, so packing only beachwear would be optimistic. If reliable high heat is your priority, June may feel too variable.

Plenty of sunshine, but keep plans flexible

About 9.1 hours of sunshine within 15.1 hours of daylight gives June plenty of scope for time outdoors. That does not mean uninterrupted blue skies: there are about 8 rainy days during the month, so a completely dry holiday is not something to count on. Keep outdoor plans movable and pack a light waterproof rather than letting rain catch you unprepared. The averages cannot tell you how wet your particular stay will be, or how long any shower will last. June works best if you are happy to adjust beach plans around the weather instead of needing sunshine every day.

The sea is the main compromise

The sea averages around 21°C, which puts it on the bracing side for swimming. If you like warm water and long, leisurely swims, this is the clearest reason to think carefully about June. Sea temperatures have ranged from 20°C to 23°C between years, so the feel of the water can vary noticeably; do not assume a warm afternoon means an equally warm swim. You may prefer shorter dips, with something dry ready afterwards. For travellers who mainly want to sit by the sea and swim occasionally, the water temperature is less of a drawback than for those planning to spend much of the day in it.
