Matt Newbury, who runs monthly full moon swims in Paignton said he would be taking to the water at Goodrington Sands as part of an informal event.
“It took me almost a year to swim in a full moon,” he said.
“We started trying to do full moon swims about three of four years ago, but it was either raining or cloudy and we didn’t see a moon for months, but we know it’s up there.”
“It’s amazing because you get that whole moon river, that trail of light on the water,” Mr Newbury added.
“It’s just really magically being under the moonlight. It’s a bit daring, it’s a bit naughty.”
Chagford Pool, near Dartmoor, said it had sold out its ticketed full moon swim and was looking to host more in future.
