@idefix37 thank you so much for the answer. i was confused a little bit when i saw that place showed 41 and then 42 on that hottest day on July 25, and i was overly excited thinking we broke the UK all-time record of 38.5, but now i see that was not the case. Well, actually on that Thursday we did broke the record eventually, but only at 38.9, which was registered in Cambridge !:0) thanks for clarifying!

Which one is correct ?

THANK YOU
