UK Sees Record Low Temperature For July

Craig spotted this on today’s BBC weather report:

Currently there is no mention of the record low from the Met Office, who, though admitting that July is ending up “wet and dull”, are still talking about “a record-breaking heatwave”.

@wanstead_meteo: #July temperature finished just 0.1C above average, Rainfall of 70.1mm is 162% of average. Sunshine of 174hrs is 91% of average.
What is the +0.1c based on, CET?
If so it is not yet finalised.
Monthly records in this area going back to 1797 – they include Plaistow, Greenwich and Wanstead. I calculated it because I wanted to compare what the exact area I live in was like going back to the point. A lot of the detail is lost when you just refer to CET – a region that is over 100 miles NW of me
Thanks.
What period do you use for “average”. 1961-90?
1981-2010 – the same as Reading University
From my daily record of my solar PV system output which relates directly to sunshine:
– July 1 2015 was 36% lower than July 1 2014
– Total July 2015 was 14% lower than total 2014
So no records this year. Basically less sunshine due to more cloud.

Well spotted, Craig.
What are the odds Aunty’s enviro correspondents fail to write a full article about it?
Thanks Paul.
I just asked via their blog
Hi there, There was a graphic up on the BBC weather report yesterday evening showing a record low for July of 1°C for southern England. What station was that recorded at and what/where was the previous record? Thanks Craig
I’d also like to know what other station records were made as the CET chart Stephen showed is quite a surprise. Heathrow probably didn’t set a new record (RAF Northolt was over 5°C min) but I’m sure there are a few other surprises. Bruce has it as the coldest since 1898 beating the prev record by -1.1°C.

It will be interesting to see where the individual record was set and by how much. Are we looking at frost hollows or was this something else? Does UHI make this new record all the more unusual?
No media fanfare so far…
Sennybridge 0.9C
That’s in mid-Wales, but the graphic has southern England.
South Newington recorded 1.1°C and looks to be a WMO site. Known to get cold central temperatures

The plot of CET min shows a spectacular drop on 31st July:
It was one of the coldest July nights in entire 350 year CET, including Little Ice Age, yet late July has warmer nights on average than early July. Maybe it’s the biggest ever cold anomaly in July, where anomaly = daily value minus 1961-1990 ‘standard normals’ (black line in the plot).
Just noticed the pale blue line in plot shows minimum from 1878 onwards, rather than full 350 years. I guess the min CET data earlier than 1878 may be more unreliable.
The United States had snow in the mountains this week. It may have been a very widespread anomaly, but we will have to wait and see how August goes.
Temperature tampering, mis-reporting, non-reporting, false attributing, failure to put things in context, etc., etc., etc. One is tempted to say, “folks, you can’t make this stuff up”. But clearly, they can and do.
Which is why I decided to compile my own series of figures – all from original texts which cannot be altered. It is very time consuming – inputting every year – max, min, rain and sunshine – takes 45 minutes
The Hadley Centre Cental England Temperature for July 2015 is 15.9 C, continung the run of 8 months from December 2014 of each month being cooler than the corresponding month a year earlier. May, June and July have all been below the average from 1659 and from 1772.
There goes John Hammond’s future at the BBC. Only record highs are allowed.
Paul, thank you very much for this article because I was starting to think I was just feeling the cold far more than I’ve ever felt it before.
The Met Office are quite clearly being dishonest to the point of being fraudulent. They have clearly been pushing the one hot day at the expense of being honest about the cold.
“A period of abnormally and uncomfortably hot and usually humid weather.
To be a heat wave such a period should last at least one day, but conventionally it lasts from several days to several weeks.”
AMS Note that this means those “heat waves” in the DESERT southwest are misnamed.
(http://glossary.ametsoc.org/wiki/Heat_wave)
“A heatwave is now defined by three or more days of unusually high maximum and minimum temperatures in any area.”
BOM Note this is a NEW standardized value for “unusually high max and min” whatever that means
(http://www.abc.net.au/news/2014-01-14/bureau-of-meteorology-provides-national-heatwave-definition/5199712)
There is no actual scientific value in either of theses. They are just as vague as a psychic saying “You will meet a tall, dark handsome stranger”. Could be a cute single guy, could be the cop coming to arrest you for meth distribution. Vague on purpose to cover every possible contingency. No science here folks. Move one.
Don’t worry, after Slingo and her apparatchiks at the Met Office have finished Mannipulating the data with their £100,000,000 supercomputers July 2015 will take up its rightful place as the hottest July since records began.
That’s what Climate Science is all about, Hiding the Decline.
Climate science is about making observations and inventing processes to explain them that involves Man and CO2. And you’re right, if the invented stories become too unbelievable then you simply change the observations until they fit an acceptable explanation.
Judith Curry says the most believable temperature records are HadCRUT4 from http://www.metoffice.gov.uk/hadobs/hadcrut4/data/current/download.html and BEST Land and Ocean data from http://berkeleyearth.org/data/ Land + Ocean (1850 – Recent)
All the more credit to Hadley Centre for updating the data at
http://www.metoffice.gov.uk/hadobs/hadcet/data/download.html so quickly (who says civil servants don’t work at the weekend ?)
Maybe more accurate to say their automated code is working at the weekend?
Today we ate our lunch out at Pitlochry. We chose to eat outside and not indoors because it was pouring with rain and the T was 8˚C (that is +8) – all the cosy tables by the fire were occupied. For weeks now the T hasn’t got much above 13˚C. Sympathy with Scottish Sceptic.
The record warmth and record cold are both linked to the meandering jet stream and I believe this is down to the state of solar activity. Wait for more news on spectral shifts being larger than normal and those having greater impact on atmospheric circulation than previously believed.
The fact that the MET office chose to highlight a single hot day at Heathrow as a Dreamliner passed by the thermometer at expense of reporting the aberrant cold July that has serious negative impact on tourist industry is fine testimony to how shit the MET office is. Are there no good people there who want to speak out?
Well, according to http://www.sciencedaily.com/releases/2015/07/150709092955.htm the National Astronomy Meeting at Llandudno featured a paper by Valentina Zharkova that predicted that solar activity will fall to LIA (Maunder minimum) levels in the 2030s.
I had to take my sweater off this afternoon in Hampshire UK as I strode along in sunlight!
I live in Brussels where yesterday morning it was also distinctly chilly (7 oC). I cycle to work each morning and in the locker room I met a Norwegian colleague who had recently been to his log cabin for his habitual summer holiday. He explained that one day rain was forecast but in fact they had snow! In July!
He also said that in Norway they use the expression ‘tropical’ for when the temperature rises above 20oC. Sadly, and very unusually, Norway has so far not experienced one ‘tropical’ day this summer.
In a similar vein, back in February we visited Tenerife and the people who live there permanently said that they had never had such chilly cloudy winter.
Anecdotal I know, but I wonder if nature is trying to tell us something?
