Festival Weather by Month

How to read these numbers

Each festival is grouped by the month its main days fall in. The temperatures, rainfall and weather score are long-run averages from roughly 15 years of Open-Meteo archive data taken at the venue coordinates on the festival's own calendar dates — not a generic city-wide monthly average.

The weather score condenses all of it into one number between 0 and 100: rain sets a ceiling, and daytime and overnight temperatures move the score within it. Roughly, 80+ is reliably excellent, 60–80 is a good bet, and below 50 means packing for weather is part of the plan.

Picking a month

If you want the best odds of warm, dry weather, mid-July to late August is the sweet spot almost everywhere in the northern hemisphere. If you care more about avoiding heat — or about sleeping well — late June and September give you comfortable afternoons at the cost of colder nights. Whatever month you pick, the individual festival pages show the live forecast as soon as the dates come into range.
