It's really hot over here in the UK also. It has been in the 90's today and I can really tell as my leg has started to hurt a lot more than usual! It didn't help that I went to college and the bus was late so we had to sit out in the heat for about an hour until it came!
I used to always love Summer but don't like it that much now! I have to have the temperature just right which is nearly impossible! If it is too cold, I hurt too much and if it's too hot, I hurt too much so you just can't win! It's a good job we have air conditioning although that hurts me too sometimes!!
Hope you're all doing OK in the heat and that it doesn't get to you too much!
