August stays warm and busy — about 23°C/13°C, with the same peak-season crowds and prices as July and slightly less rain (around 105mm). The International Music Festival runs into August, filling the castle setting with concerts.
The midday crowd crush continues: the narrow Old Town lanes fill with day-trippers from Prague (and Austria, given Linz is only 1h45 away) between late morning and mid-afternoon.

Cesky Krumlov in August — Full Picture

The midday crowd crush continues: the narrow Old Town lanes fill with day-trippers from Prague (and Austria, given Linz is only 1h45 away) between late morning and mid-afternoon. The overnight strategy remains the single best piece of advice — wake to empty cobblestones, visit the Castle Tower and Cloak Bridge early, and let the buses arrive while you've already had the town to yourself.
Rafting on the Vltava is at its summer peak, the river warm and the gentle Class I float family-friendly. Riverside terraces are in full use.
Late August begins to ease slightly as European school holidays wind down. Like July, August is fully open and lively but demands early booking and patience with crowds.
