As I expect something of an indifferent month, synoptics wise, though with warm air generally, and a constant threat of Spanish plumes (but with nothing like the sunshine-levels of a 1976, 2006 or 2018) I'll go for 17.9C, please, Roger. And 65mm of rain, please.:oldgrin:

You are certainly welcome to join in, the contest does run on an annual basis (from last December to this November, to align with the four seasons).

17.2C And 92.4mm please-I think it will be a warmer month than last but still rather wet thanks to thunderstorms aka a couple of short heatwaves followed by several thundery breakdowns.

Probably quite a warm month with near normal amounts of rain, going 18.1 and 71.6 mm. 

Don't let me edit this ;)

(edited just the EWP +0.5 to keep it unique, later forecast hit my earlier value).
