Warm days, with some hotter spells

June suits travellers who like summer warmth but would rather not spend every afternoon avoiding the heat. Days reach 25°C around 62% of the time, while 16% reach 30°C, so there is a real chance of hotter weather rather than just mild sunshine. Keep more energetic plans for the morning and leave room for shade at midday. Evenings are a different proposition: the average night low is 17.4°C, and the coldest nights can fall to 14.5°C or below. A light jumper or jacket is sensible for sitting outside late, even when the afternoon has felt properly hot. Pack for that contrast rather than heat alone.

Dry weather makes outdoor plans easier

Rain is unlikely to dominate a June stay, with about 2 rainy days during the month. That makes this a sensible time for travellers who want to spend most of their holiday outdoors without constantly rearranging plans around showers. It is not a guarantee of a completely dry trip, so keep a flexible indoor option rather than assuming rain is impossible. There is about 10.9 hours of sunshine within 14.5 hours of daylight, giving you plenty of scope to shift activities away from the hottest part of the day. Sunglasses, sunscreen and a hat deserve space in your bag; heavy wet-weather clothing is less of a priority.
