Was the hottest temperature recorded yesterday higher than 35.9 C ? No, the highest recorded temperature yesterday was 33.0 C in Hawarden and that is the hottest day and highest temperature recorded this year, so yesterday when I said that 1976 was hotter, I was absolutely correct, we will see later if it does get hotter than 1976, I suspect it will but as it stands right now its not been hotter than 1976
For the record, the current highest temperature recorded in the UK is 38.7 C
