The North East Skinny Dip saw about 400 people dash into the chilly waves at Druridge Bay in Northumberland.
HUNDREDS of brave souls stripped off and ran into the North Sea as the sun rose this morning.
The mass dip, which began back in 2011, raises money for MIND – a charity which provides advice and support to anyone experiencing mental health problems.
The annual event, which is now in it sixth year, is organised by Jax Higginson, from Sunderland.
People of all ages embraced the liberating experience as they frolicked in the water against the backdrop of a golden sunrise.
Some of the nude crowd held hands as they ran into the sea and had an invigorating start to the day.
Before sunrise, skinny-dippers were treated to entertainment from a percussion band and a female fire eater.
There were camp fires on the beach as the growing crowd, which included campers, got ready to strip off.
An onlooker said: “It was a really good atmosphere. “They were all laughing and joking early on but when they started the countdown they became quite nervous.
“It was a magnificent sunrise and a special moment when the countdown began and everyone rushed into the sea.
“They ran into the water screaming because of the cold.
“For quite a while they were splashing each other and jumping into the waves.”
After Northumberland saw a good start for the swimmers, the forecast for today predicts a dry day in the east, but rain in the west during parts of the day.
A band of cloud and patchy rain, occasionally heavy, will move across western parts during the day.
