Warm enough for summer clothes, with some hotter days
June suits travellers who enjoy warmth but are happy to adjust their pace when it gets hot. Temperatures reach 25°C on 57% of days, while 15% reach 30°C, so sustained outdoor plans need some flexibility. Humidity averages 72%, which can make the warmth feel less comfortable, particularly around midday. Put more demanding walking into the morning and leave room for indoor breaks when the heat builds. Lightweight, breathable clothes are sensible for daytime, but bring a light layer for evenings. The average night is mild rather than hot, and cooler spells mean summer clothing alone may not cover every part of your trip.
Long daylight helps, but keep a wet-weather option
The catch is rain: June is warm, but it is also a wet month. A compact umbrella and a lightweight waterproof are more useful than assuming you can plan every day outdoors. There are about 6.1 hours of sunshine within 14.9 hours of daylight, so long days should not be confused with uninterrupted sun. Keep weather-sensitive plans movable and have an indoor alternative ready for wet periods. The daylight gives you room to shift outdoor time earlier or later rather than forcing it into the hottest part of the day. June works best if you can accept changing conditions instead of needing a fixed outdoor timetable.
