As we get ready for the first full day of music, Radio X ponders which acts could be set for the festival's famous secret gigs.
Find out whether the Somerset festival is set for a scorcher this year...
Glastonbury 2017 is almost upon us, and with the festival opening its gates on Wednesday 21 June this year, it remains to be seen whether music-lovers will be greeted by glorious sunshine or dreaded rain.
This year seems to look VERY promising with no mud baths forecast.... but you may need to pack a waterproof just in case of a couple of showers.
The week leading up to Glasto will be "mostly sunny" with highs of 29 degrees.
Better still, Wednesday - which is the day most punters arrive and pitch their tents on Worthy Farm - has been predicted as having "clear skies"... but you may need to cover up on the long journey to the camp sites.
Thursday 22 June will be more cloudy, while the weekend will be significantly cooler, with the chance of showers on Saturday and Sunday.
While we can never totally be sure about the English weather, one thing we can bank on is the fact there are still plenty of acts to still to be announced for the festival.
With Glasto releasing its official stage times, and confirming "TBA" slots on The John Peel Stage and The Park Stage, Radio X considers some of the huge bands that could still make an appearance at Worthy Farm...
Take a look at who we think could be set for a secret gig:
