September keeps the summer's warmth and loses most of its crowd once the schools go back. The light turns golden over the Castle in the late afternoon, the beer gardens are still open, and walking all day becomes a pleasure again.
It is also harvest season. Burčák — cloudy, barely fermented young wine — is sold in plastic bottles from street stands for a few weeks, and the vineyard at Grébovka in Vinohrady holds its own harvest celebration. The Dvořák Prague festival fills the Rudolfinum.
28 September, St. Wenceslas Day, is a public holiday. Prices stay high because conference season begins, so book the good hotels in advance.

- 28 September (St. Wenceslas Day) is a public holiday; large shops close.
