Warm days, with some hotter spells

Expect summer warmth rather than constant intense heat. Days reach 25°C on 59% of occasions, while 30°C is reached on 8%, so very hot afternoons are possible but not the norm. For walking around the city, mornings are a sensible choice if you dislike heat; keep the middle of the day flexible for shade or a rest. Humidity averages 72%, which can make warm conditions feel less comfortable when you are active. Evenings are generally mild, but cooler nights still occur, so a light jumper is more useful than a suitcase filled entirely with beachwear. June suits warmth-seekers better than travellers who prefer cool conditions for exploring on foot.

Sea swimming is a realistic part of the trip

The sea averages 22.4°C in June, making swimming a reasonable expectation rather than something reserved for those who enjoy cold water. The year-to-year range is 21°C to 23°C, so your reaction will still depend on your tolerance: the cooler end can feel fresh when you first get in. If you want very warm water, June may be a compromise rather than your ideal choice. There are about 10 hours of sunshine a day, giving you plenty of scope to combine swimming with other outdoor plans. Bring sun protection and allow for shade breaks; comfortable water does not mean the sun feels gentle once you are back on land.

Allow for rain, not a washed-out holiday

June has about 7 rainy days, so it is better approached as a sunny month with a chance of disruption than as a guarantee of dry skies. You do not need to plan the whole holiday around rain, but avoid making every day dependent on staying outdoors. A lightweight waterproof is a practical addition, especially if you would rather keep going when the weather changes. The generous sunshine and long daylight leave room to shift outdoor plans, although the averages cannot tell you when rain will arrive or how long it will last. June is a good fit if you can accept some weather flexibility in return for warm days and swimmable water.
