Glastonbury weather forecast: Latest Met Office update ahead of festival

As Glastonbury Festival draws ever closer, those lucky fans with tickets will be wondering whether to pack their wellies before setting off for Worthy Farm.

While it’s still too early to get an accurate forecast of Glastonbury week itself, which will begin on 26 June and conclude on Sunday 30 June, we can take a look at what the weather’s looking like at the moment.

That hasn’t stopped some revellers from casting their own gloomy predictions, given the last two years have seen festival-goers blessed with remarkably sunny weekends in Somerset.

Previous years haven’t been so lucky, with 2016’s edition experiencing flash floods in the area the week before the festival, creating a distinctly muddy landscape that fans had to navigate around.

This week there has been a noticeable shift in the weather, after the start of June was marked by low temperatures and plenty of rain showers.

The Met Office reports that a strengthening of the jet stream, “generated by temperature contrasts in North America, will cause a shift in the UK’s weather this week, with a ridge of high pressure toppling across the UK ahead of frontal systems being driven along by the jet.

“The westerly wind will bring temperatures back up to average quite widely, and becoming above average in sunnier periods mid-week.”

Met Office Deputy Chief Meteorologist Dan Harris said: “In stark contrast to the first half of June, where temperatures have widely been below average, we are expecting to see a steady uptick through the second half of this week, rising to around or above average, and it will likely feel very warm for those in the sunshine.

“This initial spell of warm conditions isn’t expected to last too long however, as it turns more changeable through Friday and into the weekend with areas of cloud and rain spilling east across the UK.

“Temperatures this week are likely peak at around 24°C or 25°C on Thursday and Friday in the south, though more subdued in the northwest, with the influence of cloud and showers at times more likely.”

He added: “Behind this front is an unsettled weather regime, with frequent showers and some longer spells of rain from Friday and through the weekend. This unsettled theme to the UK’s weather is likely to continue into the start of next week.”

Explaining why it’s not possible to offer a forecast for 26 June, he said: “In terms of an outlook for the end of the month and Glastonbury, it’s simply too early to give an indication on the likely conditions at a specific location at this range, as even small changes in the Atlantic can have big impacts on the dominant weather regime in the UK.”
