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.

December 2015 – Freakishly mild, but wild and wet.

December 2015 was easily the mildest December on record. The mean of 7.8 degC was 3.9 degC above average. Nationally it was also the wettest calendar month on record. At Durham it was the wettest December since December 1978.

Storms propelled by the jet stream were mainly to blame, it says, with contributions from the El Nino weather phenomenon and man-made climate change.

The raging River Tees at High Force on 6th December 2015. I’ve never seen as much water coming over there in my life.

Numerous species of plants flowered months early, believing it to already be Spring. There were 4 nights when the temperature remained above 10 degC.

Christmas Day was the wettest day of the year in Durham in 2015. Indeed it was the wettest Christmas Day on record here since records began. There was 45.4mm of rain recorded over the Christmas Day and Boxing Day period. This was all due to Storm Eva.

Met Office : Further rainfall and flooding across north of the UK

January 2008 – Very wet and mild

January 2008
A very wet, but mild month, with almost twice the normal amount of rainfall. The total ended up just 0.2mm under the 100mm mark. This eclipsed the previous record for January at Ferryhill by some 35mm. The year started with a very wet New Years Day, with 19mm faliing on the 1st. This would have been the ‘wettest day’ in most months here, but it was beaten on the 21st when a new wettest day for January was set. 23mm fell in the 24hrs. There was 4cm of snow cover on the 3rd January, but it soon melted.

June 2007 – A wet one, and very dull

June 2007
This month has proved to be quite a wet one, with 80.0mm of rain falling (although 111.8mm recorded in Durham) – not a remarkably high total (146% of the 1971-2000 mean), but considering the first 11 days of the month were completely dry it’s quite noteable. Only two dry days were experienced after that. It could have been much wetter, the extreme weather which caused extensive flooding in South Yorkshire towards the end of the month stayed just to the south of us in Ferryhill.

One thing that has been noteable about June 2007 is it’s extreme dullness. It was one of the dullest Junes in North East England – the total of 101.5hrs made it the 4th dullest since 1882 and the worst sunshine total since 1987 (89.4hrs). It was less sunny than May, which was itself less sunny than April. It was thought this ‘reverse’ sequence must be unique, but in fact it has now happened 7 times in the April-June period since 1882.

April 2007 – Warmest April by far

April 2007
Yet another record breaker, April 2007 was a whopping 0.6 degC warmer than the previous warmest April (1865) on the Central England Temperature series. Again, a long term record beaten. Also noteable is the fact that 2006 was the warmest year on record and the first third of this year is more than 2 degC warmer than the equivalent period in 2006. Quite incredible.

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 was slightly above average.

Again, I use my record from Ferryhill to show the daily conditions.

July 2006 – The warmest month on record.

July 2006
This month has created history as it is the warmest month on record. The records go back to 1850 at Durham, and this month has beaten July 1983 to the highest monthly mean temperature. To put things into perspective, the average temperature for July 2006 is 2 degC above that recorded as an average for July 1976, a year which was previously regarded as being the best summer in living memory. There have been only three days that haven’t reached 20 degC in the month, and 14 days consecutively over 25 degC since 16th is an extraordinary run of maxima.

It was also extraordinarily dry, with rain on only 4 days for a total of 6.6mm.

The sun shone for an average of 8hrs per day in July 2006 at Durham. It was the 3rd sunniest July on record.

My record from Ferryhill for July 2006 shows just how warm things were.
