Plan for heat, not just warmth
June is firmly hot: 55% of days reach 30°C, so that temperature is not an occasional bonus. On the hottest days, walking around can become hard work, particularly if you prefer to keep moving throughout the afternoon. The warmest 10% of days reach at least 34.4°C, making shade, drinking water and somewhere cool to pause sensible priorities. Put your more active plans earlier in the day and leave room to slow down at midday. Light, loose clothing, a hat and sun cream belong in your bag. If you dislike heat, June's dry weather may not outweigh the effort of managing it.
Long sunny days, with little need for rain gear
With about 12.1 hours of sunshine across 14.6 hours of daylight, June gives you plenty of scope to shift outdoor plans away from the hottest part of the day. Rain is unlikely to dominate a holiday, though roughly 3 rainy days means you should not assume every day will stay dry. Keep plans flexible rather than packing for persistent wet weather. Evenings are generally warm enough for light clothing, but a thin layer is useful if you feel the cold: the coldest 10% of nights fall to 16.9°C or below. The overall balance favours travelling light, with sun protection taking priority over bulky waterproofs.
