Absolutely in love with this thread. Though this is more "a month that got a record that *didn't* deserve it" I was absolutely distraught over June 2023 beating the old joint records of 1940 and 1976, especially 1976. To be fair. A lot of this just stems from my general dislike for modern climate change records but I used to love June 1976 for the exceptional maxima in the latter half of the month
In contrast, I was very happy about September 2023 tying with September 2006 overall. I found September 2006 to be incredibly boring meteologically with only 1-2 days actually exceeding 30°C, despite this. Mainly due to warm minima, 2006 beat many famous Septembers like 1911 and 1906 in overall mean temperature. September 2023 was an incredible month due to it's beginning heatwave. 7 days over 30°C was absolutely uprecedented compared to previous Septembers. Nevermind all in a row! Though I remember at some point, a weather model even forecasted maxima as high as 36°C in parts of the south for 2 consecutive days. Even though I hate heatwaves, I still wish this had verified.
