Let’s face it - the start to autumn could have been better. September 2017 in the Anglia region was colder, wetter and duller than in normally is.
Despite not being spectacularly over budget in terms of rainfall, it was the wettest September for 16 years.
The provisional rainfall total for the Anglia region in September 2017 was 62 mm (2.2 inches), which is only 8 mm above the long-term average for the month. It represents 15% more rainfall the normal.
It is a measure of a relatively long run of dryish Septembers since 2001 that means such a modest rainfall total breaks such a record.
The average September rainfall in the Anglia region for the 30-year period of 1981-2010 which is currently used to measure whether a month is wetter or drier than normal is 54 mm (2.1 inches).
For the past 16 years since 2001 that average was just 41 mm. And 2017 was some way off making into the list of ten wettest Septembers on record in East Anglia. For that, the rainfall total would have need to be somewhat greater than 90 mm (3.5 inches)
The north coast of Norfolk saw winds gusting to 60 mph as the first named Atlantic storm of the season breezed through to the north of the Anglia region.
Storm Aileen overnight from 12th/13th September saw a peak gust of 60 mph at Weybourne on the Norfolk coast while the wind gusted to 58 mph at Wittering in Cambridgeshire.

Sunshine was also in short supply for the third month in a row.
Not all data has been collated yet but provisionally it was the dullest September in the Anglia region since 2008.
A ‘normal’ September sees more than 4¾ hours of sunshine per day but this month saw a little over four hours per day.
Since July, the Anglia region has seen only 90% of the normal sunshine and it has been since the dullest July to September since 2010.
September was colder than average too although not as cold as September 2015.

The highest temperature of the month in the Anglia region was 23.1°C recorded at Little Paxton in Cambridgeshire on the 4th. That is in stark contrast to September last year when it reached 33.0°C there on 13 September 2016.
The lowest temperature of the month was recorded at Santon Downham on the Suffolk-Norfolk border when it dipped to 2.8°C on the 15th.
