Glastonbury 2025 is officially set to be one of the hottest in history — with temperatures forecast to hit 33°C just as Worthy Farm’s 500 football-pitch-sized site fills with music fans.
I’ve done Glasto in all weathers (mudslides, torrential rain, blazing heat!) — and if you’re heading there this week, trust me: heatwave planning can make or break your weekend.
This isn’t just about looking good — it’s about staying safe, avoiding heat exhaustion, and keeping your festival vibe alive all weekend long. 🎪✨
Here’s your ultimate guide — packed with pro tips, personal experience, and expert-backed data — so you can stay cool, hydrated and fabulous at Glastonbury 2025.
1️⃣ Choose the Right Tent Setup (Yes — It Matters!)
Bell Boutique Glamping (Stephi’s Pick!)
After years of camping every way possible — the ultimate cool option for me is Bell Boutique glamping.
- Light, breezy bell tents
- Natural airflow (you’ll actually sleep!)
- Beautiful interiors (trust me — waking up happy = priceless)
- Stress-free set-up → so you can head straight to the action 🎶
If glamping’s in your budget — go for it. It makes a huge difference in a heatwave.
If You’re in a Standard Tent:
✅ Reflective tarps under & over tent (bounce heat away — SeatPick tip!)
✅ Line inside walls with foil for extra reflection
✅ Pitch in morning shade if possible (study the trees before set-up!)
✅ Ventilation: 2 vents open on opposite sides for airflow
✅ Tight guy lines for airflow gaps
✅ Avoid dark tents — lighter colours trap less heat
2️⃣ How to Cool Your Tent & Actually Sleep
At Glasto, you’ll likely be in your tent 3–6 hours max per night — so those hours need to be quality:
✅ Airflow is everything — open doors safely at night
✅ Keep clothes/bags sealed (condensation = soggy festival fashion)
✅ Sleep with skin exposed (loose cotton layers)
✅ Nap late afternoon when tents cool a little (not mid-day!)
💡 One hack: sleep with a cool flannel on your chest or wrists — works wonders in stuffy tents!
3️⃣ Hydrate Like a Pro (It’s Not Just Water)
When it’s 33°C and you’re walking miles around 500 football pitches worth of site, you sweat — a LOT.
✅ Pack electrolyte sachets (magnesium, potassium, sodium)
✅ Drink regularly (don’t wait till you’re thirsty!)
✅ Alternate water & electrolyte drinks
✅ Add coconut water or fruit for extra hydration
✅ YES to salty snacks: crisps, nuts, olives — you need them
Remember: alcohol dehydrates fast. If drinking, 1-for-1 rule (1 water per alcoholic drink).
4️⃣ Cooling Tricks You Haven’t Tried
✅ Pulse point cooling:
- wrists
- neck
- behind knees
- ankles
- temples
✅ DIY cooling mist: water + mint essential oil
✅ Wear a wet scarf around neck (old-school but genius)
✅ Keep mini ice packs in cooler
✅ Freeze bottles of water — doubles as coolers & drinks
✅ Cooling towels — grab one on Amazon
✅ Spray SPF mists = cooling & protecting in one
5️⃣ Shade & Smart Planning
Think like a festival pro:
✅ Use festival cooling zones & first aid tents — they’re there for YOU
✅ Pace your walking — don’t trek all 500 pitches in peak sun
✅ Avoid peak queues between 11am–3pm
✅ Plan shady breaks between stages — plot routes with trees!
6️⃣ Know the Danger Signs
🚨 Dizziness or wooziness
🚨 Nausea
🚨 Racing heart
🚨 Headache
🚨 Clammy skin or cold sweat
🚨 Muscle cramps
If you feel any of these:
→ Find shade IMMEDIATELY
→ Sip electrolytes slowly
→ Cool pulse points
→ Rest — tell a friend or find first aid
