Those of us who live in the Northern U.S. States often have hotter weather than Britain but that had to do with being more landlocked while they have the North Sea/North Atlantic cooling them off. Here in Michigan we are often cooler than States below us because we are surrounded by the Great Lakes which cool us off.

That makes sense. In Melbourne we tend to have pretty extreme temperatures compared to the rest of our latitude - mostly because we get north winds coming across a desert, and south winds coming straight up from Antartica...
