The Met Office have forecast rain for both Isle Of Wight festival and London's Hackney Weekender.
In a specially produced video, the weather specialists has predicted a mixture of sunshine and showers for Saturday on the Isle Of Wight - while Sunday is set for a deluge, with 'heavy bursts' on Sunday, clearing later ahead of fine weather on Monday.
Saturday is set to be the brighter day at the Hackney Weekender, with plenty of sunshine and a small chance of showers. Rain on Sautrday night will cause havoc for footwear on Sunday, with rain continuing through the day at the Hackney Marshes event.
Wet weather has already caused havoc on the Isle Of Wight, with festival goers forced to sleep in cars overnight on Thursday after rain and mud made festival car parks inaccessible.
