Don’t want to derail too much, but 10023 has it right about London (and basically all of Ireland outside the west coast): it’s wet and rainy, but not humid. East Coast US cities feel worse on average during the summer than London or Dublin, given the same temperature.

You walk around Midtown or Back Bay on an 85 F day in July for 10 minutes in a dress shirt and your lower back is a goddamn swamp. You don’t get this in Dublin or London. Those big day-night swings in temperature are a good giveaway.
