Prague and the Bohemian towns beyond it — a compact, walkable region with a real winter and a short, warm summer. Daytime highs in Prague and Bohemia run from about 2 °C in January to 23 °C in July, an annual range of roughly 21 °C.
Measured against a city trip, the conditions hold up May to September. May is the most consistent single month: highs near 18 °C, nights around 8 °C, and roughly 77 mm of rain across the month.
What rules months out here is temperature, not any composite judgement. January is the weakest month on these criteria.
Visitor numbers follow their own curve. Recorded overnight stays peak in the two weeks from 2 July at about 1.9 times an average fortnight for this region, against 0.5 times in January. On the separate question of how much tourism the area carries all year, Prague sits in the 27th densest of 294 European regions, at 13.2 overnight stays per resident a year.
April and October sit just outside the window, with part of the month working and part not. These are usually the interesting weeks: conditions are close to the peak-season answer while prices and crowds are not. On recorded overnight stays that holds: April and October run about 55% below the July peak. The map lets you check them fortnight by fortnight rather than trusting a monthly average.
What Prague and Bohemia is known for
- Prague Castle is the largest ancient castle complex in the world by area
- The Charles Bridge dates from 1357 and is worth crossing before about 8am
- Cesky Krumlov's old town wraps a bend in the Vltava and is a UNESCO site
- Karlovy Vary's colonnades dispense hot mineral water you are meant to drink, not bathe in

Nearby regions
Figures are 30-year climatology sampled at Prague, Cesky Krumlov, Karlovy Vary, Kutna Hora and Plzen, averaged across those locations, from ERA5-Land reanalysis fitted with a harmonic seasonal cycle and a trend term, evaluated for 2026. Sampling named towns rather than averaging the whole region avoids blending valley and mountain conditions into a figure true of neither. Cells are about 0.08° wide, from ERA5-Land's 0.1° grid, which is itself driven by a 0.25° (~28 km) atmospheric reanalysis — so individual valleys, sheltered bays and single summits are not resolved. In steep terrain read these as conditions for the wider area rather than for one village. They describe typical conditions, not a forecast. Read how the climatology is built.
