North Suffolk coast here (well 3 miles away) and it is SO hot and humid. I like a dry Mediterranean heat, but this wet, humid, horrible heat saps your energy. I don't feel like doing anything. I get a headache if I do go out in it, can feel my blood pressure rising. I am sorry for those who have to go to work in it.
We went down our field a bit earlier and could feel a breeze there, under the trees, but it's dropped now. So I am indoors with curtains shut and fan on, watching a Suitable Boy, and envying them the monsoon. 
I have been thinking of getting the cats a cool mat. If I do, you can be sure the weather will change.
