Vejret i Český Krumlov (Krumlov) i august

August here runs from the mid-twenties to the low thirties, or turns cool and rainy in the low twenties, and regulars tell you to bring the raincoat either way. Our row gives 26.2C reading as 27C with 83.5mm across 11.5 days - a wetter month than its reputation. The rest of their advice is about people rather than weather: the city is packed, the bridge and the old square are worst on the hour, and the fix is to see them before breakfast and spend the middle of the day in the quarters the crowds skip - the Jewish quarter, Kampa island, Mala Strana, the hill. Nights fall to 16C. The record: humidity 66 percent, 10.5 hours of sun and AQI 51.

Forum posters are candid that January and February aren't for everyone, describing the cold as genuinely annoying if you don't enjoy it, with recurring forum threads literally titled asking whether visiting in January is a mistake. Posters note real seasonal closures - castle interiors and the theater shut for winter, though the courtyards stay accessible and the tower remains open in the off season. Posters who do visit in winter describe a real payoff: the town without tourist crowds, with one enthusiastic visitor specifically praising the evening views from the castle vantage point as stunning. Posters generally confirm shuttle transport around the town itself stays reliable even in mid-January conditions. Posters generally rate January as cold and closure-limited but genuinely rewarding for visitors who prioritize a crowd-free experience over convenience.

July is peak season in Český Krumlov, and the forum's advice is entirely about the shape of the day rather than the month: day-trippers from Prague and elsewhere arrive around 11am and leave about 4pm, so the town is jammed in the middle and much quieter either side of it. Their two fixes are really the same fix — be at the castle ticket office before 9am, and stay the night, because the place is described as magical once the coaches have gone. On weather, July averages 24°C but is genuinely wet: sixteen rain-days, the sort of month where an evening indoors is no hardship.
