If you want to go full sensory, find a cinema that isn’t a multiplex. The Prince Charles Cinema in Leicester Square shows cult classics and old musicals. You can watch Singin’ in the Rain ironically—or unironically—while the streets outside flood.
Better yet: catch a matinee at the BFI Southbank. It’s right on the river, so you can watch the rain hit the Thames from inside a glass foyer. Feels a bit like being inside a poem about loneliness, but in a good way.
Rainy Day London: Best Things to Do When It Rains in London
Take a “Rainy Walk” (Yes, Really)
I know, I know—you’re already wet. But hear me out. Put on a waterproof jacket and a pair of boots. Walk along the South Bank when it’s drizzling. The street performers will be gone, so it’s just you, the river, and the wet cobblestones reflecting the lights.
It sounds miserable, but it’s actually romantic in a gritty, London way. The city smells like wet earth and exhaust. It’s the same city as sunny London, but with a different personality—sulky and poetic.
