Český Krumlov (Krumlov) hava durumu: Eylül

Austria-forum threads on September (a broad Austria thread, but the numbers track Linz specifically) describe a month that cools noticeably as it goes: mild, pleasant days around 18C early on, dropping toward 14C by the end, with nights following the same slide from around 10C down to 7C. The one firm piece of advice: flurries are unlikely this early, but rain is a real possibility, so a proper rain jacket earns its place over hoping to skip one entirely. The record: 21.7C days, 12C nights, 81mm of rain across just over ten days, 8.6 hours of sun and an AQI of 39 - warmer than the generic Austria-wide read suggests early in the month, with the cooldown arriving on schedule by the back half.

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.
