I am in Swansea, so used to having rain continuously. I hope those London folk enjoyed their wet trip back this afternoon, after throwing away their lead for the second time this week... 
As far as clothing is concerned, I had a soft shell fronted jacket on. Best of both worlds really, as rain does run off nicely, even if not actually waterproof, but chest vents cooled me down too.
My mate had a waterproof over jacket on, but he was fed up of the flapping, so into his jacket pocket it went.
