Prague winter weather can be quite crisp and usually you will be happy to put on gloves, a warm hat or scarf and layer your clothes.
Snow usually comes and melts before Christmas or doesn’t come at all until January. There is even a Czech saying that goes like this: “St. Catherine on ice, Christmas on mud”. St. Catherine’s Day is on Nov. 25, so if you trust the folklore wisdom, you can see what the weather’s like on that day and you’ll know what to expect at Christmas.
But this year temperatures in the Czech Republic during the Christmas period should be above the long-term average, according to a regular monthly forecast issued by the Czech Hydro-meteorological Institute. Daytime highs may reach up to ten degrees Celsius. Temperatures are expected to drop towards the end of the year, but it should be still relatively warm for the time of the year. The highest levels of precipitation can be expected during the first week of January.
