Traveller notes on Karlovy Vary in July
Notes from nearby Dresden (110 km away)
Karlovy Vary doesn't have its own notes for July yet — these are about Dresden, close enough to share the season.
July is Dresden's warmest month — the forum notes it runs hotter than June and regularly reaches 30°C, against a monthly average high nearer 24°C. The thing worth knowing before booking, though, is the river rather than the weather: low water on the Elbe has been common between June and August in recent years, and levels depend on Czech dams upstream deciding how much to hold back, so July river cruises have been cancelled outright and substituted with bus tours. The city itself is unaffected — green, and full of parks and gardens along the banks — but it is unwise to build the trip around a boat.
