Campers have begun pitching their tents for this year's Latitude Festival in Suffolk as temperatures continued to soar.
Up to 35,000 people are expected to attend the music and arts event at Henham Park, Southwold, over the weekend with day tickets for the Saturday now sold out.
The headliners are Kraftwerk-3D, Foals and Bloc Party and other performers include Bobby Womack, soloist classical trumpert player Alison Balsom and Eddie Izzard in the comedy arena.
Organisers have urged as many festival-goers as possible to use public transport, cycle or walk in order to minimise disruption on the roads but some tailbacks are expected.
Forecasts suggest the event should be rain-free - avoiding scenes of muddy car parks and fields experienced in previous years.
