I've been looking at the extended weather forecast for London. I'll be arriving on March 29 and leaving on April 2 . It seems that I'll be okay with a raincoat if I bring a jumper for layering. I'll also have a cardigan and some long sleeve tees as well as a scarf, hat, and gloves.
I was thinking about bringing my winter coat but get the impression I probably won't need it. The lowest temperature that is predicted for the days I will be in London is 40f (4.4c). I'm assuming that the lower temperatures will be in the middle of the night.
Does my plan seem correct?
