Traveller notes on Carcassonne in May
Notes from nearby Toulouse (85 km away)
Carcassonne doesn't have its own notes for May yet — these are about Toulouse, close enough to share the season.
Toulouse takes its weather off the Pyrenees, and the forum's warning is about how fast it turns: locals describe leaving the house wrapped up on an overcast morning and the sun arriving an hour later. May averages near 21°C by day and 12 overnight, with rain on about a dozen days, and a French May at large can swing from 5°C to the mid-20s. Layers, and check the forecast a day or two out rather than packing on the month. If the Pyrenees are the point, regulars call May iffy for high walking — long stretches of path are clear, but sheltered sections can still hold real snow.
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.
