Lots of festivalgoers will have been pretty dismayed when they looked out of their window (or tent) this morning – and the recent rain means you can expect things to get pretty muddy! But you can still enjoy your festival experience if you're prepared. Check out what's going on where you are, and plan your packing...
If you're heading out to see Drake and Nicki Minaj tonight, wrap up warm – the temperature is expected to fall to 15 degrees, so even if you work up a sweat when you're dancing, you'll want enough layers to keep you warm for the journey home. Wireless ticket holders for Rihanna's show tomorrow should be a little bit luckier with the weather. Sunshine and showers are predicted, so a waterproof jacket and high SPF suncream are recommended.
T in the Park
It's a good job the acts at T in the Park are hot because the weather is going to be a little bit chilly! Clouds and rain are forecast tonight, with average temperatures of 15 degrees. The site has already experienced heavy rainfall, so It should be a little bit dryer tomorrow, so headliners Kasabian and Swedish House Mafia won't get too soggy.
Unfortunately the Bloc event that was set to take place in East London's Pleasure Gardens has been cancelled due to overcrowding. At the moment the official festival website is closed because of excess traffic, but full refunds will be available from the site soon.
Regrettably the event at Harewood House in Leeds has been cancelled because of the severe weather conditions and heavy rain. Fans will miss headline acts Matt Cardle and the Human League. Full refunds will be available from Monday - go to http://www.harewood.org for details.
The Henley Festival
Fans looking forward to watching Blue and Lulu on the floating stage tonight should watch out for rain – with heavy showers predicted, we'd recommend waterproof jackets and wellies. If you're heading to Henley to watch Olly Murs tomorrow, you should get to see some sunshine too.
