Thanks GW. Some amazing stats there.
July has come in dead level, but 05-17 will have been distorted by the very warm July's in 2006 and 2013. Don't have the exact figures to hand, but excluding those 2 months, July's anomoly is probably as negative as August.
Looking at seasons as a whole, Winter is up 0.3C avg per month, Spring up 0.2C, Summer down -0.07C, Autumn up 0.5C
I'm really looking forward to starting using the 1991-2020 30 year series. When 81-10 series came into use, much was made of 11 out of the 12 months going warmer compared to 71-00. December of course being book-ended by the classic 1981 and 2010 Decembers! Unless we get a couple of really hot summers in the next 3 years, I reckon July and August will both fall on 91-20 compared to 81-10, maybe even compared to 71-00.
Notwithstanding the warmer Autumns, the Summer cooling will take a bit of explaining in some quarters
