The Carling Weekend: Reading and Leeds festivals is now underway with weather forecasts predicting a warm and sunny weekend.
Bands performing at the Reading site today include Razorlight, Kings Of Leon, Interpol, Maximo Park and Albert Hammond Jr.
At the Leeds site, fans are looking forward to shows from the Smashing Pumpkins, Klaxons, Jamie T and New Young Pony Club.
Friday is set to have the lowest temperatures, but fans can expect to be soaked by the sun on Saturday and Sunday as temperatures reach the mid 20s.
Festival organisers have had to work tirelessly during the summer to ensure the event went ahead as planned.
After the heavy rain in July, many areas of the site were flooded and the water level was above the knee in a number of camping areas.
Camping zones at Reading are named Green, Yellow, Brown or White and have various lettered sub-fields.
In a message posted on the festival's website, organiser Melvin Benn said: "It has been a very difficult month. When we got on site on July 25th, Green camps A, B, C and D were waist high in water from the floods, Yellow camps F, G, H and I were over 3ft deep in water.
"I always said the festival was more important than the weather.
"The weather forecast for the weekend is actually quite good - too late to dry the land but at least we can enjoy some sun."
Carling weekend is the last of this summer's major festivals.
