Your June weather guide
WarmWeather in Prague in June
June is a good time for Prague if you want warm days for exploring on foot, but not if you need reliably dry weather. Average daytime highs of 22.5°C suit being outdoors without constant heat, while nights average 13°C, so keep a layer handy. The catch is rain on about 12 days: pack for showers and leave some flexibility in your plans. It suits travellers who prefer warmth to intense summer heat.

Warm days, with cooler evenings
Light clothing should work well during the warmer part of the day, but a jumper or light jacket earns its place in your bag after sunset. The averages hide a fairly broad range: the warmest 10% of days reach 28.5°C or more, while the coldest 10% of nights fall to 9.2°C or below. That makes layers more useful than packing only for summer heat. On hotter days, put longer walks earlier in the day and take a shaded break around midday. June suits a city break spent largely outdoors, provided you are comfortable adjusting your pace and clothing as conditions change.
Long daylight, but keep rain plans flexible
June offers about 6.5 hours of sunshine within 16.1 hours of daylight, so there is plenty of light for flexible plans, though you should not expect uninterrupted sun. Rain is the main compromise rather than a reason to rule the month out. A light waterproof and shoes you can comfortably wear in wet conditions are sensible choices. Keep indoor time movable rather than committing every day to being outside. About 12 rainy days does not mean those days are wet throughout, but it does make an entirely dry stay something you should not count on. Use dry spells for longer walks and keep an eye on the forecast.
