Highest Temperature Since 1949 – Next To The Tarmac & Jumbos!

And guess where?
The UK has experienced its September highest temperature in more than 65 years, with 32.2C (89.96F) being recorded by lunchtime.
The Met Office said the high was recorded at Heathrow airport .

NOT A LOT OF PEOPLE KNOW THAT 
I guess this is the same weather station as they used in 2015 – which you pointed out here.
Do they ever learn? (Rephrase that: Do they think we never learn?)
Have our plane spotter friends been able to say what aircraft had just landed when the peak was recorded? I seem to recall the last time there was an anomalous reading from Heathrow that an A380 and a couple of 747s had just arrived (super jumbos are grouped together as air turbulence they generate can destabilise smaller aircraft).
I’ve only just seen this post, and haven’t had time to delve further. But the same subject was discussed (in detail) at two of Clive Best’s posts last year:
The wind across that part of the UK is currently from the South East, so any heat from passing jets would drift towards the Met Station.
It has always bothered me that so many “official” temperatures are measured at airports. Changing stations seems to alter these “records”, but in which direction on what day? Was the temperature recorded 65 years ago done at Heathrow at lunchtime? If not, where?
65 years ago there was a lot less Tarmac and and a lot less aircraft, so no valid comparison could be made any way.
Well it was a major item on the BBC lunchtime news. I wonder how many people think Heathrow might not be the best place to take temperature measurements. Gravesend was the next hottest place, but I recall in the past that there are problems with the site there.
Yes, here it is, covered by Tallbloke. https://tallbloke.wordpress.com/?s=gravesend
Note: ‘since 1949’. Carbon dioxide levels were a good deal lower then, so such temperatures as recorded today can’t automatically be linked to rises in man-made emissions.
Btw it’s about 18C and cloudy here in SW Scotland 😐
According to their Twitter feed:
https://twitter.com/HeathrowNoise?lang=en-gb
“Good morning, we are currently on easterly operations, landing on the northern runway (09L) and taking off from the southern (09R)”
So any larger aircraft are likely to be passing (and most likely exiting the runway near) the Met Station.
Without knowing exactly when this alleged “highest September temperature in more than 65 years” was recorded, it’s difficult to pin down which particular aircraft might have been responsible. This site allows you to select a 1 hour period, and see all the arrivals during that time:

If anyone knows the exact time I will be happy to look in more detail. FlightRadar24 has a playback facility, and at least one site logs all arrivals in detail, but I’m b****** if I can find it at the moment!

You may be aware of Paul Homewood/ Tallblokes articles on a Met station which seems to always read hot
Then now on BBC newsweb :
Another location has recorded a steady 33.0C on the weatherhq feed………….
London City Airport!
It says The UK’s hottest day of the year so far – and the warmest September day since 1911 – has been recorded in Gravesend, Kent, where it reached 34.4C (93.9F).
The Met Office can go on as much as they like about a few tenths of a degree, But last night they forecast 28C for Chewton Mendip in Somerset; we made 20C.
So less than 24 hours before, they couldn’t forecast better than 8C between forecast and reality – useless.
13:08/09 BST is my best guess for the temp record ably assisted by Emirates A388.

London City was hot.
Whereas Jersey (airport), that used to be described as the warmest place in the British Isles, being just that little bit further south, could only manage a paltry 25deg maximum. I suppose they just need bigger jets?

The usual suspect Gravesend snatched it, 34.4C according to BBC (I can’t confirm it from any other source yet though).
Same old, same old, when are they going to sort those two sites out? – which isn’t to say that that it has been a hot day for September.
You would have thought that by now the fact that all these highest temperatures are followed by “since…..” would suggest that temperatures have not increased much. If the calamatists were right, highest temperatures on record should be a regular feature.
Maybe it got to 26C her, by 5pm you need a cardy. 8pm there was quite a dew as there was this morning. This year seems to have only had 2-3 days without such reasonable dews. No rain yet tonight.
BTW one year ago the Met Office blog tried to address accusation of bias at Heathrow in 2015
“Heathrow saw a short gap in the clouds shortly after 14:00 GMT which resulted in a similarly short lived peak in temperature, while Kew Gardens remained cloudy. “
How likely is it that a summer max high temp record is set on a day that only has a short break in the cloud cover?
The implication of the temperature not exceeding 1949 is totally lost on alarmists, as usual. They’re incapable of putting two thoughts together, let alone being logical.
It’s worth remembering that airport “Met” stations are not sited to give “weather observations” but to measure the actual temperature and wind OVER THE RUNWAY. This is what’s matters to pilots. Conditions at well-sited Met station perhaps a mile or more away are of no operational interest.
It’s downright dishonest to use raw airport data without explanation.
Next time I burn my large brush pile in the north field, I’ll take the temperature next to it while forking some stragglers onto the conflagration. Bet it would be higher than at the other end of the field.
It is of course downright dishonest to report major airport weather data without explaining that airport “met” stations are sited to report actual conditions OVER THE RUNWAY. This is what matters to pilots, who need to check aircraft performance against actual runway conditions – not those at some perhaps distant, well-sited weather station.
Where is the “homogenisation”, so often employed by climate science, when it’s really needed?
Damn, you must be freezing!!. We’ve be 90+F with 90humidity here in DC. We truly feels for you.
