Mean temperature for 2022 here was 12.1°C which is joint warmest with 2014.
I think the reason 2022 didn't beat 2014 was the coolness of the nights which brought the mean temperature down somewhat. The dryness of the ground made for a plethora of unusually cool minimum temperatures throughout the summer.
Conversely my mean maximum temperature for 2022 was the highest in my record.
2014; 2022
