September 1919 – Heatwave then snow

Just after the end of WW2, September 1919 was an unusual month as it went from a late summer heatwave to early winter snowfall in the space of few days. A hot southerly flow allowed temperatures to climb as high as 32.2C at Raunds on the 11th September 1919. However by the 12th, the windflow came in from the North Sea and maxima temperatures plunged to the teens. The real dramatic change came on the 18th, when a low pressure system tracked to the north of Scotland, deepened as it moved into the North Sea and a vigorous cold front …

The last 5 Septembers in the UK according to Trevor Harley

2016 An extraordinary month. Overall very warm, with a CET of 14.6, making it the second equal warmest September from 1910. The first five days were unsettled, and then southerly winds brought hot humid air to the south. 29.3C was recorded at Gravesend on the 7th. It was slightly cooler from the 8th to the 12th, and then 34.4C was recorded at Gravesend on Tuesday 13th, a real record breaker, in many ways: it is the hottest day of the year; it is remarkably late (you have to go back to 1926 for one later); it is the first time …

Monthly Weather Summary September 2020

Here’s what happened in September 2020. After a wet day on the 2nd, September weather was quite decent until the 22nd. There was a short heatwave in mid-month when the temperature hit a lovely 26.6 degC. Towards the end of the month the weather turned very Autumnal indeed. Temps plummeted after the deluge on 23rd, and the maximum temperature on 24th was only 10.2 degC. Quite cold for September. In fact I’m told it was one of (bottom 20) the coldest September days since 1900. This cold spell was due to a depression in the Southern North Sea dragging in …

September 2019 was mostly dry, but still wet!

The headline says it all. September 2019 was really dry and quite pleasant for the first three weeks before the rains came back.  Only 8.1mm fell in the first three weeks, as pressure remained high. Remarkable that the total for the month ended up at 81.0mm, making it a ‘wet’ month overall. That just shows how monthly statistics can completely mask what lies within. Temperature was very equable, with no really warm days, but no really cold ones either. The warmest temperature came in a short 3 day spell grouped around 20th, when 21.9 degC was reached. The coldest was …

Monthly Report – September 2018

A very average September temperature wise, there were some warm days at the start of the month and another on 26th. Rainfall total was slightly above average, mainly due the extremely wet 2 day period of the 20th and 21st. The total for these 2 days was 44.6mm, which contributed more than half of the final total for the month. High pressure then dominated until the end of the month, with some chilly nights in the last 10 days.

The River Floods Again – September 2012

The very wet Summer of 2012 continued into Autumn. The river burst it’s banks again in the city. This red car (Ford Ka) became quite famous as it bobbed about in front of the new Radisson Hotel (due to open a couple of months after this photo was taken). A view of the flood from the Passport Office/National Savings Building. The red car can just be seen in the left mid-distance. The Figures There was exceptionally heavy rainfall and flooding towards the end of the month. The rainfall was spread across two days, with 47.4mm recorded on the 24th and …

River Wear in flood again, Sepember 2008

The River Wear in spate again in mid September 2008. The main wear, normally visible about 4ft above the river is almost totally submerged. The river was 6” away from bursting it’s banks. This was the scene in Croxdale in September 2008 as firemen begin the cleanup process after another flooding episode at The Honest Lawyer Hotel. The River Browney burst it’s banks and inundaded the hotel and motel rooms.   Further North in Northumberland, there was a disastrous flood in Morpeth on 6th September. The centre of low pressure was slow-moving over Cent England on the 6th. There were …

September 2006 – Warmest September on record

September 2006 Another one for the record books, September 2006 is the warmest September on record, beating September 1729 in the CET series. This record had stood for 277 years up to this year, and was the longest running record of any ‘warmest month’. Recently broken ‘warmest’ records are seemingly gathered in the second half of the year, with the longest standing remaining record for July-December resting with December 1974 (this was broken quite decisively in December 2015). The absolute high for September was raised to 27.1 degC on 21st of September 2006. There were no cold nights, and rainfall …

Durham Cathedral Sunset September 2005

This was one of my favourite weather photos from Durham City. It was taken on the way up the steps into the Durham University Students Union building (Dunelm House) in New Elvet. The sun was going down behind Durham Cathedral. That was the last I saw of the sun that night as I disappeared into The Durham Beer Festival being held at Dunelm House.
