September was 'a month of two halves' despite the heavy rain and flooding

I think the most interesting thing about September is the difference between the first three weeks and the final week.

We saw pretty decent weather until the 23rd with most of the wet and windy weather affecting Scotland and Northern Ireland (a reversal from what we had this summer).

The South East had some fairly warm weather during the first few weeks with 29C widely reported on the 8th and 9th.

Rainfall amounts across the country away from the North West were unusually low during the first three weeks.

Then, we welcomed in Autumn with a bang, between the 23rd and 26th humid air came up from the Azores and formed a low pressure (the deepest we have had in September for 30 years).

This brought high rainfall totals to some parts of the country, especially Northern England and Wales and strong, driving winds.

Many places saw a month's worth of rain in just three days, while Ravensworth in North Yorkshire had 130mm, double what they would normally have in September.

Overall - Rainfall overall has been pretty mixed, typically East Anglia and central Scotland were below average with 50-75% of a typical September falling.

The big story is the above average rainfall for northern England, here we had 50% more or even double the normal months rainfall.

Mean temperature was around average for eastern areas and a little below average for western areas.

Sunshine was around average, Southeast England was a little above and northwestern areas were a little below.

So on the face of it you may think that September was average it was however anything but, it’s one we will be talking about for many years to come.
