The rain was part of a downpour that struck the southwest of the country today - although there were some breaks of sunshine.
Revellers took refuge where they could under tents and canvas marquees while the heavens opened up.
But others simply embraced it as an inevitable part of the experience and continued partying.

Already many have been forced to battle 25 hour long queues and chaos caused by flooding.
However, if the weather does improve, the rain showers are unlikely to leave.
The Met Office shows that the chance of thundery showers from this afternoon through to Saturday lunchtime are still high, with sunshine on Sunday.
