It really isn't and a 45°C average temperature in Summer isn't going to happen this century, London might make a 30°C average. This year, though it was the hottest Summer, didn't get over about 23°C average with peaks of a few days over 30.
London is about 5° higher than the rest of the country, on a regular day it's about 2° but it was higher this summer.
We'll just complain about the humidity as we always have.
