Prague weather month by month: what to expect and what to wear

Prague's weather has one reliable habit: it changes its mind. A bright April morning can end in sleet, and an October afternoon can pass for late summer. Below is the shape of the year, month by month, without made-up averages. For live forecasts use the Czech Hydrometeorological Institute (ČHMÚ), and for the season-level view there is Prague weather by season.

Winter: December to February

December is the darkest month. Around the winter solstice the sun sets at about four in the afternoon, which is why the Christmas lights matter. Expect cold, damp air, a fair chance of snow late in the month and very short days. Our guide to Prague in December covers the markets and the holidays.

January is usually the coldest month. Frost is normal, snow is possible, and the sky can sit flat and grey for days under an inverze (a temperature inversion, with cold air trapped in the valley). Pack a proper coat, gloves and shoes with grip, because cobbles and tram platforms turn slippery.

February is much the same, with the first hints of longer light. It is a quiet month for visitors, and one of the cheapest to travel in.

The cold in Prague is rarely extreme, but it is damp, and damp cold finds thin layers. Wool socks and a scarf do more than another jumper. Dress for the platform and the street, then peel off inside: trams, museums and pubs run their heating generously. The cloakroom (šatna) is a normal part of an evening out, usually staffed and often for a small fee.

Spring: March to May

March is the most undecided month. A warm day can be followed by a week of cold rain. The clocks go forward on the last Sunday of the month (28 March in 2027), so the evenings suddenly stretch. Wear layers you can take off.

April brings the first real outdoor days, fruit blossom in the parks and the Easter season with its markets. Showers are frequent. An umbrella and a light waterproof will do more than a heavy coat.

May is generally the gentlest month: green parks, open terraces and long evenings. The Prague Spring music festival traditionally opens on 12 May. It is a busy month too, so book trains and rooms early.

Summer: June to August

June has the longest days of the year, with light lasting well past nine in the evening. It is warm rather than hot, though thunderstorms start to appear.

July is typically the warmest month. Heatwaves happen, and afternoon thunderstorms can arrive fast and leave just as fast. If your trip is in high summer, the article on Prague weather in summer covers shade, water and storms.

August is similar to July, and the city is full of visitors while many locals are away. Apartments without air conditioning can be stuffy at night, which is worth remembering when you book.

Terraces fill by seven in summer and the river embankments stay busy until late. If heat bothers you, do the Castle and Old Town in the morning, retreat to a shaded park or a museum at midday, and come back out when the light softens.

Autumn: September to November

September is the quiet star of the year. Days are still warm, crowds ease and the evenings turn cooler. The separate guide to Prague in September goes through it in detail.

October is golden and cooler, with mist in the mornings and the first frosts possible late in the month. The clocks go back on Sunday 25 October in 2026, and the dark arrives an hour earlier. What time it is in Prague has the details.

November is the grey month: damp, short days, bare trees and a long wait for the Christmas lights. It is also the cheapest time for a city break, and good for museums and concerts.

Spring and autumn are not mirror images. Spring arrives in fits and starts, with the temperature swinging from one week to the next, while autumn tends to ease down more gradually. If you hate being caught out, autumn is the kinder season to pack for.

Planning around the weather

Rain is possible in every month, and Prague has plenty indoors. If you can choose, the shoulder months (late April to May, and September to early October) pair decent weather with thinner crowds. Our best time to visit Prague guide weighs weather against cost and events, and the what to pack for Prague in every season piece turns the weather into a suitcase.
