Highest monthly mean MSL pressure at 09z for Wokingham in September in the
past 34 years is 1024.0 in 1986, (this Sept 1022.9). The highest for any
month in that period is 1031.7 in Feb 1993. The true mean from the AWS 00-24
data this Sept. is 1022.20 .

Thanks. Interesting that Feb 1993 (like Steve's Jan 1992) wasn't a
notably cold month IRRC, which I tend to associate with nearby
anticyclones in winter. Maybe it was mostly centred just
to the south of the UK to give a westerly or south-westerly flow..
