Warm days, with hotter spells possible

Expect summer warmth, but not relentless heat every day: 58% of days reach 25°C, while 11% reach 30°C. That makes June a sensible option if you enjoy warm weather but do not specifically want very hot afternoons. There is still reason to keep midday plans flexible, particularly when walking or spending long stretches in direct sun. Around 10.7 hours of sunshine within 14.8 hours of daylight leave plenty of scope to move more active plans into the morning or later afternoon. Pack light clothing, sun protection and a light layer for cooler evenings. The coldest 10% of nights fall to 17.6°C or below, so warmth after dark is not guaranteed throughout your stay.

Swimming is appealing, but leave room for rain

The sea is warm enough for swimming, with June temperatures ranging from 22°C to 24°C between years. That suits travellers who want to spend time in the water, though your own tolerance will decide how comfortable a longer swim feels. Rain is the main interruption to plan around: about 5 days receive measurable rain during the month. That is enough to justify a light waterproof and some flexibility, but not a reason to rule June out for an outdoor holiday. Avoid treating a rainy day as a guaranteed washout, since the monthly figures do not tell you how long showers last. Keep swimming and outdoor plans movable rather than tying them to particular days.
