Prague weather and when to visit
The chart below gives a reasonable indication for Prague weather from the averages for sunshine, temperature and rainfall in Prague in historical almanacs but, Prague weather is so changeable as to make them not useable for a two week holiday etc.
Current Prague Weather Forecast
Hotel rates change in Prague on bank holiday weekends so be careful when booking dates close to the borders of the seasons and check with the hotel about their seasons. Some hotels include Christmas in their HIGH Season dates whilst others include in their standard rate. Prague in it's "Top" seasons would be for Christmas, New Year and possibly Easter.
Prague in January and at the end of the year are about the same i.e. Prague weather is generally cold but not wet and it can snow at any time. Before Christmas i.e. Prague in it's low season, October/November generally ties in with the Opera/Ballet season in Prague. Although you will find performances all year round, the season brings the more established Czech companies and internationally renowned troops to Prague. The big advantage is that you can see these events in some spectacular locations, at a fraction of London prices and with a greater choice. The disadvantage is that Prague in Winter has weather which can be bitterly cold. If it is culture that you want, I would advise a visit to Prague in November as it is not yet very cold, Prague accommodation is reasonable and Prague tickets are still available on the day. After Christmas the temperature will be zero or less for long periods.
Prague in Spring i.e. March/April until the end of October is a bit more stable after Easter. All Prague hotels move to a common price level (some call it Prague in mid-season, others high season). In the spring months the Prague weather is changeable from cool and clear in March to drizzly in April/May. The weather in Prague in the summer months when the city is at it's most crowded can be very hot. The cobbles radiate heat. I always recommend Prague in Spring and Autumn to visit when the weather in Prague is warm but not hot and when the wind is fresh but not chilling. If you have the opportunity for a quick getaway to Prague at the end of February or early March and the Prague weather is good then you can get high quality Prague accommodation for half of what you would pay for Prague in peak times.
