The traditional Christmas Day swim on Hampstead Heath, festive films at the JW3 and an evening of comedy with the Hampstead Comedy Club are just some of the things featured in our top five this week.

1. Christmas Day - Hampstead Heath swim

Hundreds will be stripping down to their swimsuits as they take part in the traditional Christmas Day swim at the Hampstead Heath ponds.

All the Heath’s much-loved swimming spots will be open, except the mixed pond which is closed for the winter period.

The ladies’ and men’s ponds are open from 8am and the Parliament Hill Lido will open from 7am.

Both the ladies’ pond and Lido will then close early at 9.30am, leaving the hundreds of swimmers expected to turn up heading to the men’s pond for the annual races.

Starting at 11am with the women-only race, other events include the all-comers race (open to everyone) and the Highgate Lifebuoys race.

The men’s pond is then expected to close at about 12.30pm.

Only the very brave will be able to withstand the icy waters with current temperatures around five degrees celsius.

Those taking part are advised to take extra care and watch out for problems associated with swimming in the winter, such as numb freezing cold injury, hypothermia and sudden immersion syndrome (SIS).

The City, which manages the Heath, advises each undertake a medical check up beforehand.

5. Sunday - Pantomime

It’s pantomime season and Jez Bond and Mark Cameron’s re-imagining of the Jack and the Beanstalk tale is receiving rave reviews. Performed at the Park Theatre in Clifton Terrace, Finsbury Park, it was reviewed by this paper as “a clever take on the traditional story that marries slapstick with all manner of meta-theatrical and literary japes”.

It has also received a five star review from WhatsOnStage and has been described as “London’s best panto”.

Starring Michael Cahill as Dame and Omar Ibrahim as Jack. Ticket prices vary. Visit parktheatre.co.uk to book.
