Glastonbury 2027 is expected to take place Wednesday 23 June – Sunday 27 June 2027 at Worthy Farm in Pilton, Somerset, after the planned 2026 fallow year. Gates open Wednesday morning; the Pyramid Stage runs Friday, Saturday, and Sunday. Always confirm exact dates on the official Glastonbury Festival website (glastonburyfestivals.co.uk) as the Eavis family announces definitive dates 12–18 months in advance. 2026 is a fallow year — there is no Glastonbury Festival in 2026. The Eavis family confirmed the 2026 fallow year to give the Worthy Farm land, infrastructure and local community a year to recover. Recent previous fallow years were 2018 and 2012. The next festival is expected in late June 2027. Glastonbury 2027 is expected to run Wednesday 23 June – Sunday 27 June 2027 (the traditional last-week-of-June slot, aligning with the summer solstice for maximum daylight). Gates open early Wednesday morning. Pyramid Stage main programme runs Friday 25, Saturday 26, and Sunday 27 June. The site fully closes Monday 28 June at midday. Confirm at glastonburyfestivals.co.uk before booking. Late June in Somerset averages 21°C (70°F) highs and 11°C (52°F) lows, with about 8 rainy days across the month. Glastonbury sits in a famously variable microclimate — recent festivals have ranged from 32°C heatwaves (2017, 2022) to mud-bath washouts (2005, 2007, 2016). No — but the legend persists because mud is dramatic on TV. In the last 10 festivals, roughly half have been mostly dry, three have been mixed, and two have been notably wet. Odds favour at least one rainy half-day across the five-day festival, but full washouts are rarer than you think. Recent years: 2024 mostly dry with one Friday shower; 2023 hot and dry (Pyramid headliners under clear skies); 2022 heatwave (32°C peak); 2019 mixed but mostly sunny; 2017 record heatwave (32°C); 2016 sustained rain and deep mud; 2014 mixed; 2010 hottest on record at the time. Pre-2010, mud years were 2005 (flash flooding) and 2007 (mud apocalypse). Yes — always. Even in dry years, the 900-acre site has poor drainage in cow-pasture areas, and overnight dew plus 200,000+ feet creates muddy paths near stages. Bring wellies AND comfortable trainers. Decide which to wear each day based on the morning forecast. Pack a packable waterproof jacket (5,000mm+ rating), waterproof trousers for sustained rain, dry bag for valuables, plastic groundsheet under your tent, and a sealed change of clothes. During rain, head to covered venues — Theatre & Circus, Avalon, Acoustic Stage. After rain stops, mud is at peak slipperiness for ~2 hours; slow your pace. A 2-3 person dome or tunnel tent with 3,000mm+ hydrostatic head, taped seams, and a proper bathtub groundsheet. Avoid pop-up tents (poor wind resistance, leak in sustained rain). Bring extra guy lines and groundsheet. Pitch on slightly elevated ground if possible — water pools in low spots within hours during rain. 2005 (flash flooding, tents floating), 2007 (mud apocalypse, cars stuck in fields for 24+ hours), and 2016 (sustained rain, deep mud across all walkways) are the three modern benchmarks. Heat is the other risk: 2017 hit 32°C with limited shade, causing widespread heatstroke incidents. Overnight lows in Somerset late June average 11°C (52°F), but the Pilton valley regularly drops to 8–9°C in clear weather. After sweating in the daytime sun, this feels brutally cold. Pack a proper sleeping bag (rated 5°C or lower) and a warm fleece for evening sets. Wellies, lightweight waterproof jacket, fleece or hoodie, sunscreen SPF 30+, sun hat, sunglasses, refillable water bottle, dry bag for valuables, head torch, sleeping bag (5°C rated), foam mat, and at least one full change of clothes in a sealed bag for emergencies. Yes if it rains heavily. The 2007 festival famously left thousands stranded in mud for 24+ hours after Sunday night rain. Tractors are deployed to tow cars. To minimise risk: check Sunday-Monday forecast before festival, leave Sunday night if heavy rain forecast, or wait until Monday afternoon for grass to firm up. Bring a tow rope. Wellies (essential), packable waterproof jacket with 5,000mm+ rating and hood, dry bag (5–10L) for phone and wallet, plastic groundsheet for under tent, sealed change of clothes in plastic bag for emergencies.
Scores are capped by dealbreakers — heavy rain, dangerous wind, thick fog or hazardous UV pull a day down no matter how pleasant the rest of the numbers look.
