Brockwell Lido, 3pm
Sun lounger: Sam Nash, 17, Lewisham, student at BRIT School (for Performing Arts and Technology) in Croydon.
In the swim: "Apparently it's going to be snowing by the end of October, so I'm trying to soak it all up. We had a half day today, so a group of us came down together. It's my birthday this weekend, and everyone's trying to look nice and tanned for my party."
