Where: Hampton Pool, High St, Hampton, TW12 2ST
The outdoor swimming pool in Hampton is kept at a nice and warm 28 degrees, so you can have a dip whatever the temperature. For when the weather does permit, you can sunbathe on the grassy bit outside or take a picnic.
There’s a separate pool for kids (also heated) and there’s even a gym overlooking the water. It’s open every single day of the year, including Christmas day should you fancy a pre or post-festive meal swim.
