Dropped to 4.0C last night, my coldest Sept night on record (since 1991)
It was completely calm for a while in the early hours.

Blimey Graham, that is a tad on the chilly side for your location.

Interesting that your coldest September nights have all been in the last few
years, any ideas on why that would be? My only thought is the possibility
that the last few Septembers have been more settled than the previous ones.

It was chilly here too, easily the coldest night of September this year (and
last year) with a minimum of 5.2C at at 07:30 this morning.

A lovely, 'fresh' sunny morning.

Currently at 09:45, 8.7C, RH 80%, DP 5.2C, 1023.5 mb (R), Wind 9 mph NNE,
2.7 hours of sunshine so far today.
