The general pattern
Summers are warm rather than scorching, winters are cold rather than brutal, and the shoulder seasons (spring and autumn) swing between the two over the course of a few weeks. Rain falls year-round in Prague; it's rarely an all-day event, more often a shower that passes through and leaves the cobblestones shining for the next round of photos.
Rough temperature guide
- December – February: daytime highs typically hover around freezing to 4°C, with colder nights. Snow is possible, not guaranteed.
- March – May: a steady climb from cool (5–12°C) to genuinely mild (15–20°C) by late May.
- June – August: typically 20–26°C, with occasional hotter spells above 30°C in July/August.
- September – November: a mirror of spring, sliding from mild back down to cold by late November.
What to pack, honestly
Layers, in every season. Prague's weather can shift meaningfully between morning and evening, and the city is built for walking on stone and cobbles, so comfortable, broken-in shoes matter more than anything weather-specific. A packable rain jacket earns its space in the bag year-round; a proper insulated coat, hat and gloves are non-negotiable from late November to March.
A note on forecasts
We're not going to pretend to show you today's live forecast here — a static page can't do that responsibly. For an accurate short-term forecast, check a live weather service a day or two before you travel; anything much further out is a rough seasonal guide at best, including the ranges above.
