How often does it rain in Prague?
Prague records around 641mm of rain a year, spread across about 127 days — roughly 35% of all days, or 11 days in an average month. That puts Prague mid-pack: rain interrupts roughly one run in three, so it pays to check the hourly forecast before a long run, but you will not be running in waterproofs week after week.
The wettest month is August, averaging 81mm across about 11 rainy days. The driest is March, with 37mm over roughly 10 days. Average lows in January drop to -1.7°C, cold enough that gloves, a headband and a thermal base layer make a real difference on early runs. Summer highs peak around 26.1°C in July, comfortable for most daytime running.
Those are ten-year averages, not a forecast. What actually matters on the day is the next twelve hours — which is what the live verdict and hourly strip at the top of this page are for.
