The popular attraction opened for the first time this year on Saturday - and the chilly spring weather meant there was a small but keen crowd going for their first outdoor swim of the year.
One of the first to take the plunge was Peterborough MP Paul Bristow - who was pushed into the pool by former Mayor of Peterborough John Peach.
The Lido will now be open throughout the spring and summer - with some early morning spots open.
Later in the season, opening hours will be extended.
