Take a look back at some of the muddiest Glastonbury Festivals of all time
With hundreds of thousands of people living in fields for five days, the weather can have a big impact on the Glastonbury Festival experience.
While heatwaves bring a challenge of their own for sweaty festival-goers, it is perhaps the more muddy affairs which stick in people's minds.
Heavy rain soon brings huge pools of muddy water to Worthy Farm, with punters left either sheltering in big top tents or diving into the mud head first.
Back in 1982, tickets for the 25,000 people who went to Glastonbury Festival cost just £8.
But those lucky enough to secure a ticket had to brave a lot of bad weather - and even more mud.
The Friday of the 1982 festival saw the highest rainfall recorded in a single day for 45 years - but as is still tradition, there were smiles all round.
After more than a decade of relatively dry years, 1997 was dubbed 'the year of the mud'.
As the rain kept coming, so too did the injuries and illnesses as festival-goers who were unprepared for the weather struggled to stay warm and dry.
Acts included the Prodigy, Radiohead, Massive Attack, Ray Davies and Sting - and the 90,000 attendees battled through to see more acts than ever before.
"People are really enjoying themselves - and not many people are leaving," Michael Eavis told ITV at the time.
He added: "It's a shame about the weather and the mud and things but the sprit is very high," Michael Eavis said.
2005 - lightning strikes
The 2005 festival brought with it two months worth of rain in just a few hours - and a few lightning strikes for good measure.
The once in a hundred year occurrence meant the festival looked more like a marsh than a farm, with people choosing to get around by dinghy instead of on foot.
2016 - yet more mud
Festival-goers faced some of the worst mud in Glastonbury's entire history at the 2016 event, after torrential rainfall hit the site in the weeks before the festival.
Michael Eavis told the Guardian 'every single bit' of woodchip in the South of England was used on the site, saying: "I’ve never seen mud like it in the whole life. This is worse than 1997."
“In all 46 years, it hasn’t been as bad as this,” he added.
