This year might have seen the warmest month in global temperatures, but the warmest 365 days in the CET series still belongs to the 11.71°C which ended on the 2nd May 2007. The graph shows all the daily mean central England temperatures for each year since 1772, with 2022 in blue, 2023 in red and 2007 in black. Up until the middle of February, 2023 was out on top as the warmest in the series, but since then the average for 2023 has very slowly cooled, at the same time back in 2007 the 365 day average was still warming. At this juncture, by that I mean the 25th of August, 2022 is now the warmest 365 days but with a mean temperature still much lower than the record 11.71°C set in 2007.
If this graph of multiple line series for each year since 1772 looks a little bit complicated, it is, so study it a moment, and I’m sure everything will become clear😉
