Glastonbury Festival 2027 Nice-Weather Probability

Hello to all you lucky Glastonbury Festival regulars and first-timers. Since we are still a ways off from heading to Worthy Farm, we have to look at the long-run averages to see what the Somerset valley usually has in store for us. You can generally expect classic British summer days where the mercury sits comfortably around 20°C or 21°C. It is perfect t-shirt weather for dancing in the afternoon, but you will definitely notice that temperature drop once the sun goes down. Those nighttime lows of 11°C mean it will feel quite crisp in your tent, so a cozy sleeping bag and a thick jumper for the walk back from the Southeast Corner are absolute essentials. The week looks very typical for late June, though Sunday stands out as the wettest day with about 3.2mm of rain expected. That is not a total washout, but it is enough for a proper short downpour that could turn the high-traffic areas a bit tacky underfoot. Saturday is shaping up to be the standout sunny day with barely a drop of rain, so make sure you are lathering on the sunscreen while you are out at the Pyramid Stage. My best advice is to pack for every season in one day; bring the sturdy boots and a light waterproof for those Sunday showers, but keep the sunglasses handy because these averages suggest a beautiful, mild week overall.
