Climate Chart of Prague, Czechia

Climate overview

Temperature

The warmest monthly mean temperature is in July, at 21.2 °C; the coolest is in January, at 1.2 °C. These are averages for each month, not daytime maximum temperatures, so they describe the broad temperature pattern rather than the range visitors may encounter from day to day. Across the calendar-month means, the unweighted mean is 10.9 °C. It offers a compact overview of the supplied period, but is not a day-weighted annual average and should not be read as a forecast for any specific month.

Rain

Mean daily rainfall reaches its highest monthly value in June, at 2.59 mm/day, and its lowest in January, at 0.75 mm/day. These daily averages distinguish the monthly rainfall pattern, not monthly totals; a lower mean does not guarantee rain-free days or show how often rain occurs. The unweighted mean across the calendar-month daily means is 1.55 mm/day. It provides a broad reference for the period, rather than a day-weighted annual figure or a measure of rainfall on a particular date.

Sunshine

Mean daily sunshine duration is highest in July, at 12.08 hours/day, and lowest in December, at 3.38 hours/day. These averages can help set expectations for daylight outdoor planning, but sunshine duration is not the same as day length and does not guarantee clear conditions. The unweighted mean of the monthly sunshine means is 7.61 hours/day per day. It summarizes the supplied calendar-month averages without indicating the sunshine visitors will experience on an individual day.

Snow

Mean daily snowfall is highest in January, at 3.68 mm/day. The unweighted mean across the calendar-month means is 0.99 mm/day. These are snowfall amounts, not a count of snowy days, snow depth or duration of snow cover, and they do not establish skiing conditions.
