Traveller notes on Carcassonne in August
Other months in Carcassonne
Carcassonne's forum is candid that September can go either way — hot or cool, wet or dry, with daytime temperatures sometimes still over 30°C but without July and August's oppressive nights. Regulars flag the near-constant wind as a defining feature of the city year-round, worth a windproof layer regardless of the temperature.
