A paramedic from South Tyneside is urging people to take the plunge and go skinny dipping in the North Sea.
Jax Higginson, from Whitburn, has - for the fourth year runing - organised a skinny dip at Druridge Bay in Northumberland.
The event on Sunday ties in with the autumn equinox - which takes place tonight.
So far, more than 300 people have agreed to take part but Jax is hoping even more will turn up on the day.
She said: “When I first started this I never thought I’d still be doing it four years later. It’s amazing.
“Last year we had 320 people taking part and this year we’ve already got that many signed up to say they’re taking part.”
She added: “There’s always some who come along last minute on the day, so this year should be bigger and better than ever before.”
Jax is asking people to make a £10 donation to the national mental health charity Mind.
This year there is also the opportunity to camp out the evening before.
The dip is due to take place at sunrise which will be at about 7am.
Jax is also hoping that the dip might be more popular after last year’s event featured in Robson Green’s Tales From Northumberland series.
Jax said: “People can come along and make a weekend of it.
“The dip takes place at sunrise but people normally arrive from 5am onwards.
“Last year’s dip was on television so a you never know people who watched it might want to come along and get involved too.”
