The best time to visit Prague is May, June and September. These months land in the comfortable band — June averages a high of 25 °C, while September sees warm 21 °C days with just 9 rain days — paired with long, bright afternoons and manageable crowds. July and August are peak season, when school holidays fill Charles Bridge and Old Town Square. Winter, from December to February, is the quiet low season, cold and short on daylight but atmospheric around the Christmas markets.

How the months are picked.A month qualifies when its average high sits in the comfortable 20–28 °C band (scored down towards 9 °C and 37 °C), rain days are few and sunshine hours are high — at least 78 % of the city's best-scoring month. July and August are then set aside as peak season (school-holiday crowds and prices) whenever at least three other months qualify; where summer is the only comfortable window they stay. Figures are ten-year averages (2016-01-01 to 2025-12-31) from ERA5 reanalysis data via Open-Meteo (CC BY 4.0) for the city centre coordinates.
When to go, and what to expect
Spring (Mar–May)
A lovely time for walkers and photographers as the city greens up — May is a standout.
Summer (Jun–Aug)
June is the pick of summer; visit July–August only if you don't mind crowds and heat.
Autumn (Sep–Nov)
September is one of the best months of the year — warm, bright and calmer.
Winter (Dec–Feb)
Worth it for festive markets and a snowy Charles Bridge, if you can handle the chill.

Frequently asked
Is Prague too hot in August?
No — August averages a high of 25.8 °C, comfortably warm rather than scorching. The bigger drawback is crowds, as it's peak school-holiday season.
What is the rainiest month in Prague?
Rain days are fairly even; May, July and October each see 12 rain days, the most of the year. Even so, showers rarely spoil a trip.
Is winter worth visiting Prague?
Yes, if you want atmosphere over warmth. January highs sit at just 3.8 °C with only 4.1 hours of sunshine a day, but the Christmas markets and quiet streets are a real draw.
