Prague Weather Overview:
Prague’s weather is affected not just by its location within Europe but from the sheltering effect of the Ore Mountains and the Czech Central Highlands which reduce the amount of precipitation in the city. Summers are usually warm or very warm with the highest rainfall for the year whilst winters are invariably around or below freezing with moderate snowfall.
All Time Highs and Lows:
In July 2003, Prague’s temperature reached a high of 41.7C whilst in February 2010, the temperature fell to a record low of -21.3C

Weather Science:
Prague lies on the northern edge of the influence of the Mediterranean Oceanic Climate and the southern edge of the continental climate this means that the continental climate, which should bring very cold winters and very hot summers, is moderated by the sea, despite it being hundreds of miles away.

The Seasons:

Spring: Spring can take a long time to get started and snowy days are common still in March and April. The temperature doesn’t get above 10C until the latter part of April but this is the driest time of the year for Prague and has dramatically increasing sunshine hours; up to seven a day on average in May.

Summer: Sunshine levels don’t rise much further in the summer and around eight a day is the best you can expect in late June. Whilst the temperatures are rising and the upper seventies and low eighties are common, the warmth can trigger severe storms making the season Prague’s wettest.

Autumn: September is a very pleasant month and temperatures generally stay in the seventies. Rainfall is easing now and with over five hours of sunshine a day on average, it’s not a bad time to visit. Into October, and the temperature drops away so that by November you can expect no more than 6C on average with less than two hours sun a day and the surrounding mountains trapping cold air around the city bringing low cloud and fog.

Winter: The cold grey conditions are well set now and with under two hours of sunshine a day being the average and with snow on the ground, it’s a bleak picture on many days of winter. Air pollution can become a problem too with low cloud and still conditions. In January and February the temperature hovers around or just under freezing.

Best Time of the Year to Visit:
May and June are the favoured times to see Prague. The weather is warming nicely but it’s not too hot to be able to walk the sights. You’re likely to have less rain that later in the summer too
