Glastonbury 2025: What’s the Weather Forecast?

When you think of Glastonbury, mud often comes to mind. But will the festival’s iconic muddy conditions make an appearance this year?

The UK is basking in a scorching heatwave this week, with temperatures set to climb to a sweltering 32°C in parts of England by Friday. High pressure is delivering clear skies and prolonged sunshine, creating ideal conditions for beach trips and barbecues, but the Met Office warns of potential health risks for vulnerable groups. As the warm spell peaks, forecasters urge residents to stay hydrated and check on elderly neighbors, while festival-goers eye the skies for Glastonbury 2025’s kickoff next week.

The heatwave, driven by a dominant high-pressure system, is bringing settled, dry weather across most of the UK. London, Birmingham, and Bristol are expected to see temperatures in the high 20s to low 30s, with Friday marking the hottest day, potentially hitting 32°C in southeast England. Overnight lows will stay in the mid-teens, offering little relief from the muggy conditions. Western areas, including parts of Wales and Northern Ireland, may see occasional showers, with a slight chance of thunder, but the east and south will remain largely rain-free. The Met Office notes that heatwave thresholds—where temperatures exceed regional norms for three days—could be met in many areas, particularly in the south.

While the sunny spell is a boon for outdoor plans, it raises concerns about drought risks after a dry early summer. The BBC’s long-range forecast suggests above-average temperatures and persistent dry conditions could continue into mid-July, increasing strain on water resources. For Glastonbury 2025, starting June 25 in Pilton, Somerset, the outlook is mixed: expect highs of 28°C this weekend, but cooler lows in the early 20s and possible showers by mid-week could bring a repeat of last year’s patchy rain. Veteran festival-goers are packing both sunscreen and wellies, recalling the infamous “Year of the Mud” in 1997 when torrential rains turned the site into a quagmire.

Health officials are advising caution, recommending sunscreen, light clothing, and avoiding midday heat. The warm weather is a stark contrast to historical extremes, like 1987’s 40mph gusts or 2007’s record-breaking festival downpours.
