Hottest Day Of Year At ………Heathrow!!

July 31, 2020

By Paul Homewood



How can they say that with a straight face?





It’s marvellous what a bit of tarmac will do!

    MET office did not mention CET anomaly upto 30th July was -1.0C, How they must have prayed for today’s hot weather. 30 days of below average temperature is not news, one hot day is!!!!!

    Deep down I bet the Met Office are secretly gutted. If Heathrow had been at full capacity it might have even have nudged 40C. As Paul has noted, absolutely nothing to do with all those plane exhausts, concrete and tarmac of course!

    Going back to the Cambridge record.

    There’s just so many alarm bells going off…….

    If the reading wasn’t affected by 45C greenhouses, air con vents, gardening practices, or the way she evidently takes the readings, is it possible she just misread 38 instead of 36?
    It all looks a bit amateurish. That would bring it more into line with nearby readings. I wonder if the reading was stored for inspection or it was reset and the MO could only check that the thermometer was actually accurate?

    I guess we will never know.

      I am expecting, new lock downs permitting, to go to Cambridge next week to see my son, where I hope to photograph the aforesaid recording station in the botanic gardens

      If You see this can you post up the photo of the botanic gardens again showing the surroundings and I will download it for reference. Anyone know it’s exact location related to the entrance? I am afraid if they demand a mask is worn I doubt if I will bother. I don’t want to fuel the current hysteria.

        Mr grim

        Thanks for that. It looks as if the station might be in a private part of the garden where they grow things on. I will see the situation next week.

        That is a very strange building close by with a semi circular roof and what appears to be a plastic covered greenhouse adjacent to it. As for the very large solar panel covered building…..

        Thanks for the coordinates. As for your comment about the half hourly readings, it is obvious that there was a perfectly legitimate temperature spike not actually recorded and the met office have interpreted the highest temperature accordingly.

        By tomorrow they will have rounded it up to 40c. Although that sounds a bit suspicious so 40.15 c sounds more scientific.

        Just had a very wicked thought looking at the foto of the Weather Station in Cambridge: My wicked thought is…. that solar panel is directly opposite and angled towards the Stevenson Screen. Are there any good snooker players out there who are good with angles and can figure out if sunlight hitting that panel can possibly illuminate the side of the Stevenson Screen opposite? Bit silly placing the solar panel there regardless just to invite a possible problem even if the angle is not right.

        Thanks for that link.

        Pardonme, your link goes to the Edinburgh Gardens not Cambridge. The grass looks good but that greenhouse looks closed. I wonder how often it appears as the highest temperatures in Scotland?

        I finally visited Cambridge last Autumn – unfortunately a few weeks/months after the event. On my visit, I was able to note:
        The Stevenson screen is not fenced off and while I was there a tractor was tilling the soil very close to it.
        The wind was easterly to south-easterly on the record-breaking day.
        To the east of the site there is an open asphalt carpark surrounded by buildings.
        To the south east is a 2 or 3 story building with numerous A/C outlets at ground level on the side facing the weather station.

        The Cambridge Stevenson screen site is also surrounded on three sides by hedges. This, and the expanses of bare soil would have made a nice little sun-trap.

    The highest half hourly observation at Heathrow was 37C at 1350Z. Where did they get 37.8C from EGLL

    I sent the first like via mobile, these are the links you need. Metric American

    Had it been 37.8C it would have been 38C. If you put in American units you get the obs in F. The max was 99F which is 37.2C. Who is lying?

      I don’t think they’re lying, just reporting the temperature at fixed times, a higher temp was reached between those times.

    Meanwhile the people that tell us our sacrifice is necessary to save the planet indulge in pointless resource consuming space jaunts:-

    Personally I believe that local weather variations are not dictated by CO2 in recent years
    but rather whatever the wind direction is.

    If the wind is coming from the North Pole we tend to get cold weather, which gives us snow & frosts in winter.
    If the wind is coming from the southwest were’re getting the warm Gulstream weather
    which tends to me most of the rain doesn’t make it over the Pennines.
    If the wind is coming from the south, then it can be bringing the hot air from Africa.
    This morning I was prepared for one warm day
    but actull day it’s being windy but cloudless
    At 10:30am I went for a run and it was no big sweat

    By 4:30pm the wind had swung around a bit and it was a warm wind from the south.

    By 7:30pm there was light rain by 10 minutes.
    At 8:30pm there was 15 minutes of thunder storm.

      typo : but actually all day it’s been windy but cloudless (until 7pm)

      “but rather whatever the wind direction is”

      A good point. Really, really unbearably hot weather here comes when a high pressure stalls in the mid-west (U.S.). It results in a NW air flow. Winds over the Appalachians experience adiabatic heating on the down slope side of the mountains, resulting in super high temperatures here.

      It’s weather.

    6:30pm BBC local news opening item
    Obviously the local Environment reporter had been heavily working on his Climate doom item
    “Here I am at Coningsby weather station on the hottest day of the year, and the Met Office have released this new report today.”
    FFS I’m only 40 miles northwest
    sure enough in the shots from the weather station their hair is blowing all over the place.
    So talk mega hot hot day there seemed a bluff.

    Indeed in the intro the main presenter had started by talking a record, and the it became apparent he was talking about last year.
    They did the item and quickly moved on.

    7pm temps dropping cos there is cloud to the south
    that is where Coningsby is.

    BTW that local news had fished around for a doom voice
    The local BBC farming show guy delivered by predicting we’ll be having 40C days
    “You see there is already more maize around, cos of the hotter temperatures”
    Twit, the reason why there is more maize these days is cos the biofuel power stations asked farmers to grow it to burn along with straw.

      Yep. The Countryfile 5-day forecast last week began, saying temperatures had been average. Then, apropos of nothing, asked us to cast our minds back to the 25th July last year when Cambridge – cue graphic – recorded 38.7C, “the highest temperature ever recorded in the UK.”

    Normal summer day here in the southern Newcastle. I don’t ride bicycle above about 35 C, too dehydrating, but often go walking on such nice days.

    Amusing that so many UK people go to Spain on holidays but the Met Office squawks when Spanish weather comes to Britain.

    O/T but James Packer has just resigned from the Board of News Corp. Said to be because of disagreement with editorial practice. James is well known as a believer in AGW and his father Rupert as a sceptic.
    Certainly The Australian here in Oz is almost a lone voice against the barrage of propaganda, despite a shortage of undressed models. It is the best performing of newspapers here in Oz. James must think “when you’re on a good thing, jump off”.

    It’s a small victory but perhaps the tide is turning against the gullible warmists.

    Hi guys.. I’ve raised a question on the Heathrow reading.. last year Heathrow and Kew Gardens reached 37.9C on the 25th July on the same day Cambridge hit 38.7C.. but as it wasn’t a national record it didn’t count!!

    • August 1, 2020 1:59 pm

      Ah, the contortions needed to maintain the lie. Must have a chiropractor on call 24/7.

    “How can they say that with a straight face?” It is their job to lie and deceive. Most likely they practice day and night until the truth burns on their tongues.

      “…hottest day of the year so far…”

      Surely this happens at least once a year? Almost by definition.

      Anyway, such occasional heat “records,” to the extent that they are valid, will just confirm the truth of the ‘wild jet stream’ theory.


      Greater Mumbai is an Indian city – once known to us as Bombay – on the West Coast.
      It has a mainly young population of over twenty million.

      Studies of blood show that 57% of the slum-dwellers, and 16% of the better-off, have IgG antibodies to Covid-19. Probably, the true figure for infection among the better-off is higher; they would have likely been exposed to a lesser viral load so that their immune systems were less stimulated. The illness has managed to spread despite its being summer.
      In any case, it means at least five million people have had the illness in a city with only one hundred thousand confirmed cases and just six thousand deaths.

      This epidemic seems to be an unstoppable mild illness, the vascular complications of which occasionally kill some old people. The only logical course seems to be to find a treatment* for these complications, and, otherwise, stop the futile gestures of control.

      *There already are treatments, so perhaps it is more a matter of publicizing them.

    This wiki photo claims to be the day after the Cambridge record.

    I’ve compared some of the hotter max. temperatures I could find documented from the garden, and the open page in a photograph of their scribbled weather records, with the lab roof. All it really shows is that in recent years the garden often reads 1.5-2.9C hotter than the lab roof.

    However, on the earliest reading I could find, 10th Aug. 2003, which was one of the garden’s previous highest readings of 36.9C, it was in good agreement with the roof at 36.7C.

    I emailed for the garden reading for 31st July just gone and they came back with 33.9C which was 1.8C hotter than the roof, but it is also suspiciously exactly the same as the NIAB max., so it may or may not be the garden reading!

    On the day of the all time record the difference between the roof and garden was 2.6C.

    None of this really helps validate or invalidate the record (the roof is a poor location/unreliable too), but there is a hint that perhaps some development or change in the landscape after 2003 is boosting the garden readings?

    If only I could find more earlier garden readings!

    Hardly surprising that Heathrow should be even hotter than usual. With far fewer planes taking off and landing, the ground-level air isn’t being mixed-up as much as it normally is and so can hold the heat from the tarmac even longer.

    I think we are aware that the standard of journalism has massively deteriorated in recent years but the attached link to an article in the Cambridge News takes the biscuit for unsubstantiated nonsense.
