Prague weather by month

June to August is the best time to visit Prague for warmth, with average daytime temperatures rising from 22°C to 25°C. September is a good alternative if you prefer milder walking weather, averaging 20°C. The catch is that summer is not reliably dry, so warm-weather packing still needs a waterproof layer. Spring calls for more layers, while late autumn and winter suit travellers happy to balance cold outdoor spells with time indoors.

Spring: warmer afternoons, but keep your coat

March is still chilly rather than comfortably mild, with daytime averages of 9°C and nights around 1°C. Bring a coat if you expect to spend much of the day outside. April makes walking more comfortable at 15°C, although 4°C nights mean you will want an extra layer after dark. May reaches 19°C by day and offers a better balance for travellers who dislike summer warmth. Its catch is rain: it averages 13 rain days, compared with April's 9. Choose April if cooler weather is acceptable; choose May for warmer afternoons, but keep a waterproof jacket handy.

Summer: the strongest choice for warmth, not guaranteed dryness

June offers warm days around 22°C without the higher average temperatures of July and August, which both round to 25°C. August is marginally the hottest month, while July has the most sunshine, averaging 7 hours daily. This is the best season for travellers who want to spend plenty of time outdoors without relying on a heavy coat. Light clothes should work for daytime walks, with a layer for evenings as average nights range from 13°C in June to 15°C later in summer. Keep rain protection close: July is the wettest month, and summer averages 11 to 12 rain days per month.

Autumn and winter: September stands apart

September is the clearest choice for mild autumn weather, with days around 20°C and nights of 11°C. October drops to 14°C by day, so layers become more useful, especially when you stop walking. By November, an 8°C daytime average and just 2 hours of sunshine make a trip built around long outdoor days less appealing. December and January are colder still, with daytime averages of 4°C and 3°C and nights below freezing. February improves slightly to 5°C by day, but nights remain at -2°C. Pack a warm coat, gloves and footwear suitable for wet conditions throughout winter. February is the driest month, but that does not make it warm or rain-free; it suits travellers who prioritise lower rainfall over comfortable outdoor temperatures.
