Glastonbury weather in 2025 is shaping up to be a hot topic for festival-goers. The UK is currently experiencing a mini-heatwave, and forecasts predict that the warm, settled conditions could persist through the start of the festival. Temperatures in Somerset are expected to reach highs of 27 degrees Celsius, with some forecasts suggesting even warmer spells as the festival kicks off on June 25.
Early in the week, festival-goers can expect dry and sunny conditions, but there is a chance of showers and even thunderstorms as the weekend approaches. Nights will remain warm, with temperatures staying in the mid-teens. While rain is possible, prolonged dry periods and warm, sunny spells are likely to dominate the festival experience this year.
Heatwave Hazards: Why Glastonbury Weather Needs Respect
Glastonbury weather can be unpredictable, but this year the main challenge will be the heat. Prolonged exposure to high temperatures increases the risk of dehydration, sunburn, and heat exhaustion. The festival site offers little natural shade, and the crowds can make the conditions feel even hotter.
Heatwaves at festivals have led to a rise in heat-related incidents, with health officials warning attendees to stay vigilant. The UK Health Security Agency has issued heat health alerts in recent weeks, emphasising the need to take precautions, especially for those with pre-existing conditions.
Essential Tips for Beating the Glastonbury Heat
Staying comfortable and safe in the Glastonbury weather is possible with a few key strategies:
- Drink plenty of water throughout the day. Aim for at least 1.5 to 2 litres daily, and refill your bottle at every opportunity.
- Wear high-factor sunscreen and reapply it regularly, especially if you sweat or after time in the sun. Don’t forget spots like your scalp and the backs of your ears.
- Choose loose, light-colored clothing to help your body stay cool. A wide-brimmed hat and sunglasses offer extra protection from UV rays.
- Seek out shade whenever possible. Use festival tents, bars, or even a portable parasol. Organisers have added extra shelter, but options can be limited, so plan.
- Avoid excessive alcohol and caffeinated drinks, as they can dehydrate you. Alternate alcoholic beverages with water to maintain hydration.
- Take breaks from the sun, especially during peak hours between 11:00 a.m. and 3:00 p.m. Use this time to rest, eat, or catch performances under cover.
Packing for Every Glastonbury Weather Scenario
While the forecast leans hot, Glastonbury weather can still surprise. Prepare for all possibilities by packing:
- A refillable water bottle and electrolyte sachets to replace lost salts.
- Lightweight, breathable clothing for day and a warm layer for cooler nights.
- A sun hat, sunglasses, and high-SPF sunscreen.
- A small umbrella or parasol for instant shade.
- Wet wipes, a flannel, or a cold pack to cool down quickly.
- A lightweight sleeping bag or a thin cotton sheet for comfortable nights.
Recognising and Responding to Heat Illness
Knowing the signs of heat-related illness is vital in the Glastonbury weather. Watch for symptoms like headache, nausea, dizziness, excessive sweating, or confusion. If you or a friend shows these signs, seek shade, drink water, and cool down with wet cloths or cold packs. Medical teams are on-site and ready to help if symptoms worsen.
Heatstroke is a medical emergency. If someone stops sweating, becomes disoriented, or loses consciousness, get help immediately.
Enjoying Glastonbury Weather: Smart Habits for Festival Fun
The best way to enjoy the festival is to pace yourself. Start your day early to avoid the hottest sun, and take advantage of cooler evenings for exploring. Pack light to avoid exhausting treks across the site. Remember, your tent will heat up quickly in the morning, so plan to spend most of your time outdoors.
Keep your energy up with regular meals, salty snacks, and plenty of fluids. If you plan to drink alcohol or use other substances, make sure friends know what you’ve taken and look out for each other.
Glastonbury weather in 2025 promises a classic British festival experience, with sun, heat, and a hint of unpredictability. With the proper preparation, you can stay safe, cool, and ready to enjoy every moment of the world’s most fantastic music festival.
