Matterley Bowl is a natural amphitheatre, which is beautiful and also means rain collects. Mud risk is high and the steep walk-out pitches make a bad weather weekend memorable.

Frequently asked questions
How often is this page updated?
Forecasts refresh every six hours near confirmed festival dates. Stored event weather updates daily. Historical comparisons appear when enough records are available.
What does the conditions score mean for Boomtown?
A single 0-100 rating of how Boomtown's event window is shaping up. Rain or dust and ground, temperature, atmosphere and wind contribute as four equal factor groups. Their multipliers are multiplied into one event-window quality score. The festival's primary risk selects the first group's rain-and-ground or dust-and-ground interpretation and shapes the label and historical comparison. It does not give any group extra weight.
Where does the weather data come from?
Open-Meteo, an open weather API that blends multiple national weather services plus ERA5 archive data going back to 2006. The same data powers many outdoor apps.
Does the historical comparison mean the festival ran every year?
No. Historical comparisons use available weather records for the location and event window, including years when the festival did not run. Coverage varies by festival, and a comparison appears only when enough records are available.
What should I pack for Boomtown 2026?
When a forecast is available, the "Pack for it" section uses expected temperatures, rain and the festival’s main weather risks. Before then, check the organiser’s camping and entry guidance.
