Glastonbury 2025: What Will The Weather (And The Traffic) Be Like This Year?

Planning for any big festival takes a substantial amount of organising before the fun starts – and Glastonbury is an entirely different beast altogether.

The UK’s world famous music festival returns for yet another year from Wednesday 25 to Sunday 29 June, where The 1975, Olivia Rodrigo and Neil Young are all set to headline on the iconic Pyramid stage, along with Sir Rod Stewart in the famous Sunday afternoon “Legends” slot.

With the annual bash kicking off this week, around 200,000 festival goers are preparing to descend on Worthy Farm in the coming days.

Here’s everything you need to know to prepare – including the weather forecast…

When is the best time to travel to Glastonbury?

Most car parks at the festival have been open since Tuesday 24 June, though the majority of people travel to the site on Wednesday, which is why it’s usually the worst day of the five-day stretch in terms of traffic delays.

Thursday is a significantly quieter travel day, but that does mean you would miss the initial excitement of the festival – and, of course, potentially your preferred camping spot.

Entering and leaving the festival on Friday and Saturday is usually quite easy because it’s already the middle of the extravaganza, so traffic levels are quite low.

Kathryn Wiltshire, National Highways’ Resilience Planner for the South West, said in a statement: “We’re reminding road users to plan ahead for Glastonbury – around 200,000 people are expected to attend this year’s festival and roads leading to the event are likely to be very busy.”

She also advised festival-goers “check our traffic and travel information channels, but whatever your journey, we advise people to set off early and allow plenty of time”.

With warm weather expected, she also recommended drivers pre-check vehicles for “oil, fuel and coolant levels and correctly inflated tyres”. 

Travel with drinking water too, and don’t forget to take breaks!

What is the best route to get into Glastonbury?

The busiest road is usually the M5, particularly junctions 25 and 23. But, the A39 and A361 get pretty full too on the peak travel days.

The A303 and A37 are the main ways for drivers to travel from London too, especially the A303 eastbound.
However, the actual village of Glastonbury is five miles away from the site meaning it’s normally pretty undisturbed by the excitement of the music festival.
If you’re dropping people off, try to avoid doing so on local roads as that can lead to more build-ups (and can mean a long trek to the actual event).

Instead, ensure you head to a Drop and Collect point – located to the east of the site, so go towards Evercreech on the A371 then follow the signs for Drop and Collect/ DC – then catch the bus to Pedestrian Gate A.

More route details are outlined on the Glastonbury website. As it notes, a sat-nav will not get you all the way to the festival site, but to the start of the Festival signage, and you should follow the signs as soon as you see them.

Also, according to organisers, those who parked on the east side of the site last year had the shortest queues at the pedestrian gates and the shortest queues getting out on Monday.

When is the best time to leave Glastonbury?

Traffic starts to build up again on Sunday, with many choosing to leave after the headline act finishes up in an attempt to miss out on Monday traffic.
Congestion only gets worse through Monday, with experts recommending setting off at around 6am as the optimum time (4pm is apparently the “worst time” to start that long journey home).

What will the weather be like at Glastonbury?

According to the Met Office, the weather is set to warm up again as the week goes on, with only one day showing a fair chance of rain.

Wednesday

For those arriving on Wednesday, sunshine should break through the overcast sky by lunchtime, with highs of 25°C expected in the mid-afternoon.

Thursday

If you’re lucky, Thursday might be the only day you’ll need to have waterproofs at the ready, as the forecast currently shows a 50% chance of rain from around 8am and winds picking up throughout the day. However sunny intervals should continue for the rest of the day with highs of 23°C.

Friday

Sunscreen is an absolute must as the live music line-up kicks off on Friday and temperatures are expected to reach 26°C. It might be another breezy one, with wind gusts potentially getting up to 32mph in the early afternoon.

Saturday

Temperatures may climb up to 26°C again from the early afternoon, with overcast skies changing to sunny intervals by lunchtime. But thankfully, it should be a dry one.

Sunday

The hot weather is showing no signs of cooling by the final day, with highs of 26°C expected yet again and sunny intervals throughout the day changing to partly cloudy by nighttime.

Monday

Packing up and getting home might just be the toastiest activity of the festival, with clear skies and sunny highs of 27°C from around 1pm – all the more incentive to depart nice and early!
