The period around the autumnal equinox appears to be getting wetter in this part of the UK.
Since 9am on Sunday 36mm has fallen at Wanstead, some 60% of the monthly total so far! Elsewhere, not too far away near Milton Keynes, Flitwick has recorded 124mm!
A look at the local stats shows that the week either side of September 22nd has been getting wetter since 2010.
A look at the rolling 10-year average since 1960 shows an increase since 2011.
Wild weather in the run up to the autumnal equinox was frequently a staple of the Septembers of my childhood but it has been absent in recent years.
Since 2013 I have been recording the ‘wind run’ data on my AWS, a stat generated by the amount of times the anemometer spins.
The results show there has been nearly two-and-a-half times more wind than the 5-year average.
Stormy weather over the equinox is one of the less frequent recurring singularities. The meteorologist Philip Eden a few years ago noted that ‘Mid-September storms’ during the period of 17th to 24th September had a frequency of 60 per cent.
