Met Office Falsify Data To Prove “Hottest Bank Holiday”

August 28, 2017

By Paul Homewood





This is quite an amazing piece of evidence that the UK Met Office are actively involved in defrauding the public.

The above tweet was published early this morning, forecasting the day’s weather (Aug 28th).

Note that the record to beat was 28.3C.

A few hours later they triumphantly sent this tweet:






Miraculously, the previous record temperature dropped by 1.1C!

Is it surprising that nobody trusts official Met Office data any more?

The lengths that the Met Office, NOAA, GISS etc go to in order to distort the truth should surprise none of us now.

But this latest piece of fraud really does take the biscuit, as  many commenters have spotted.

    Reblogged this on WeatherAction News and commented:
    Tucked away in some articles is this peach;

    There was some confusion over the record because of a ‘suspect’ reading in Cambridgeshire in 1990 – where a temperature of 82.9F was noted.

    But that number did not tally with other readings from the area, invalidating the result, Mr Claydon said.

    This bears further looking into

      We’re temps recorded in degF in 1990?

      1890 maybe, but surely not 1990.

      • August 28, 2017 11:53 pm

        The monthly summary for 1990 is in °C and meetings the 37.1°C earlier in the month at Cheltenham, Gloucester. Mentions a transient ridge on 26th-27th, the later being the bank hol that year.

        No mention on the MetO blog;


        Temperatures reached 31.6 °C at London Weather Centre on Saturday 25 August 2001, and more than twenty stations exceeded 30 °C on that day, mostly in the south-east and East Anglia. Saturday 25th August 1990 was also very warm in many parts.

        P.S. in 1890 they had temps displayed in °F but 100 years ago it was in “a” – Kelvin! 😊

        AS a Met Office observer for over 50 years I have to say it was part of the MOD in the 1960s, I went centigrade in 1972 and was one of the last to do so. In those days no record was confirmed until an investigation had been carried out to check the site, thermometer calibration etc. How times change.

    • August 29, 2017 4:17 pm

      It is utter nonsense – the Met Office is being run for the entertainment industry

    • August 30, 2017 9:17 am

      So as recent records at Heathrow also do not tally with other local readings, has the MO deleted Heathrow’s readings?

      • August 30, 2017 9:30 am

        Funny you should say that. There was a date in June this year when the official maximum at Heathrow (that remains the day’s max on ogimet) was recorded as 33.9C. The Met Office upgraded this to 34.5C. When I asked if there are two different sites at Heathrow I did not get a response. I requested the excel sheet of data – the figure remains 34.5C not 33.9C?

      • August 31, 2017 7:58 am

        Good question. How many records going either way do not tally with others? And what prompted the review in one day!!

    Still strange things in Australia.
    We had an email from BOM a few months ago advising that since the mid 1990s switch from LIG to Pt resistance, they used a data collection method that for Tmax took the highest 1-second value, no smoothing or averaging. There is a LOT of noise in 1 sec data, especially at higher temperatures. Does anyone know the details of the Met Office data capture? We have info on USA but are trying for many countries. Geoff.

      I think the Met Office use a 2 minute spacing – there were Met Office claims of a record high in March or April last year at Heathrow. When people checked the data there was a temperature spike of around 1 deg C which wasn’t present in the temperatures 2 minutes either side of it. The screen is close to one of the taxiways and wind direction was towards the screen; someone checked the aircraft movements and tallied the temperature spike with a Dreamliner turning on the taxiway.

      What I would like to know is what adjustment the Met Office use for UHI and homogenisatio. In the winter the forecasts regularly predict London overnight temperatures as 4 deg C (and more) above the surrounding rural areas; daytime temperatures are often predicted as 2+ deg C higher in London. The UHI and homogenisation figures might prove quite revealing.

        I have measured evening changes of 5-6C driving out of South London. I thought the claim from the likes of Jones was that they allowed just 1C for UHI.

      • August 29, 2017 8:44 pm

        Gerry – They have their work cut our here-

        “This seemingly innocuous observation has some pretty intriguing ramifications. In fact, it causes a phenomenon known to climatologists as the urban island heat effect, whereby dense cities have been empirically found to be up to twenty degrees Fahrenheit warmer than their surrounding hinterlands”

    And to add to the nonsense – even taking the Met Office data at face value the late August Bank Holiday has been running only since the 1960s and higher temperatures have occurred on the last weekend/ monday of August many times previously, it’s just they weren’t a bank holiday. If you look at the list of highest temperatures recorded on each day of the year in the UK (listed on the web-site) temperatures have been recorded in excess of 31c on EVERY day of August and on most days of September up to the 19th. For the current dates in August covered by this bank holiday we can see that temperatures have exceeded 33c on the equivalent dates (27th, 28th, and 29th) in either or both years 1930 and 1942. Remember also that temperatures exceeded 34c widely across England every day from 31st August to 3rd September 1906…. etc etc

    Well I never.

    OK, I’ll go along with the fraud and accept the MET Offices assertion that it’s the hottest August BH we have had.

    But then what do we expect? The planet is heating up for chrissakes, thankfully!

    And whilst the peasants in the MWP got to work and built Cathedrals right across Europe that stand today, our contemporary scientists contribution to a warming planet, with increasing beneficial vegetation is to stand around wringing their little handy’s.

    If there’s one thing to be said for communism, it’s that Stalin or Mau would have had the buggers working their little arses off to figure out how to capitalise on all that green bounty. Sure, they may have slaughtered a few million along the way, but we kind of know not to do that now. Until, of course, the planet starts to cool, millions die and no one turns the finger of blame on our current alarmist, scientific wankers.

    As it is, the human race is wasting an opportunity rarely seen in it’s history.

      “As it is, the human race is wasting an opportunity rarely seen in it’s history.”

      Yes Scot… there is the real opportunity to discuss and show clearly that our trying to capture and rebury oxidized carbon to take us back to 350 ppm (1987) is pure folly. 50 ppm is 100 gigatons. And, using only solar and wind power to do it? Even the staunchest “warmists” call it “wishful thinking”, even BS. But it is rarely mentioned. Why? After all, it doesn’t really matter if the global temperature is higher or not… after Paris that is the path we are on… the “science is settled”. But the solution is not. Mission impossible.

    • August 29, 2017 7:49 am

      I think you will find that the statistics do not show that our planet has got warmer in the last 10 years.

        I understood it had, only it was entirely within the bounds of natural variability and way below IPCC predictions. In fact so far below it’s about to drop under even their lowest estimates.

        The UAH satellite data showed no statistical warming – ie any warming was within the errors for the data – for over 18 years until the El Nino. Now that has past we are headed back to pre-‘hiatus’ levels.

    Previous high temperatures revised downwards Who would have guessed ? Whatever happened to previous variability in temperatures in smallish areas. This is why the mean temperature is measured over a large number of locations. To pluck out various ones without reason doesnt make sense. We may as well return to tearing out beating hearts as offerings .

    • August 29, 2017 12:48 pm

      Funny how it doesn’t apply to the taxiway ‘record’.

      How long have they used a 2 min interval – it is like rainfall where records are created by measuring more often in more places?

    The Telegraph says:
    “Bank Holiday Monday was the hottest on record in late August, the Met Office has confirmed. Temperatures hit 28.2C (82.8F) in Holbeach, southern Lincolnshire, surpassing the previous record of 27.2C (81F) in East Bergholt, Suffolk, in 1984.
    There was some confusion over the record because of a “suspect” reading in Cambridgeshire in 1990 – where a temperature of 28.3C (82.9F) was noted. But that number did not tally with other readings from the area, invalidating the result.”

    “Some confusion”, well that’s a good enough reason.

      There is of course no reason to doubt the veracity of records at weather station EGLL when a large jet blasts its engines directly at the weather station, even though all nearby stations show rather lower temperatures.

        I specifically predicted that they would chug along for a couple of thousand miles and then express amazement they got so far North. A daily glance at the satellite pictures of late August in any of the last ten years shows it is always possible to travel easily – for about one month, before the sea-ice grips again for the other eleven months of the year.

    “Can we beat it?” – does that mean the Met Office is trying to find ways, however instantaneously, of fiddling the numbers to find higher and higher temperatures. That is not science.

    About the same time the Beeb put together a news item showing all the extreme weather incidents across the world so far this year to give the impression of crisis.

    The fact is, the mean UK temperature over August has been lower this year than for quite a while. This is no kind of record month.

    I looked up Harrabin in Google yesterday. Apparently he was on some commitee to review BBC balance and position on various news items. It seems that they decided that since the consensus of givernments was that anthropic warming was true then they would minimise airing arguments against! Unbelievable, but it explains a lot.

  14. August 29, 2017 8:13 am

    ‘Previous high temperatures revised downwards’ – this is the new normal around the world.

    They are struggling to come to terms with ‘the pause’ so manufacturing past data has become the way forward, or one of the tricks alongside fake headlines about ‘record’ ‘unprecedented’ this, that, or the other. All froth and no substance.

      It’s more than their job is worth. If they have a mortgage and want to continue with their career, then they have to toe the party line. If they had integrity, they probably wouldn’t have joined the Met Office in the first place.

    I’ve pointed this out before, how old records are constantly re-evaluated/erased to declare a new record. It isn’t just the Met, it is the data gate keepers globally.

    There’s one poor BBC weather presenter who hasn’t been assimilated by the Borg – he always tries to moderate the warm message he is obviously forced to promote – he called it a ‘useless fact of the day’ that it might be the warmest late Aug. BH.

    And it certainly is a meaningless statistic, warmest arbitrary day in Aug since ’65 – more than 10C below the Aug record, and colder than the record for Sep & Oct too!

      Physiologists refer to the phenomenon of ‘sensitization,’ whereby the reaction to the same stimulus becomes intensified with repetition. This is the friend of the hard-sell, scare, merchant; and the sheeple are certainly well and truly sensitized, now , to any ‘useless fact of the day’ which even hints of CAGW.

      But, Nature has, fortunately, also given us the phenomenon of ‘habituation,’ whereby the reaction eventually becomes less intensified with repetition.

      It is just a matter of time – quite a lot of time, possibly to be measured in decades – when the original panic responses will be just vaguely embarassing memories.

    They settled the science some time ago of course:

    “Stabilising climate to avoid dangerous climate change — a summary of relevant research at the Hadley Centre” January 2005

    “What constitutes ‘dangerous’ climate change, in the context of the UN Framework Convention on Climate Change, remains open to debate.

    Once we decide what degree of (for example) temperature rise the world can tolerate, we then have to estimate what greenhouse gas concentrations in the atmosphere should be limited to, and how quickly they should be allowed to change.

    These are very uncertain because we do not know exactly how the climate system responds to greenhouse gases.

    The next stage is to calculate what emissions of greenhouse gases would be allowable, in order to keep below the limit of greenhouse gas concentrations.

    This is even more uncertain, thanks to our imperfect understanding of the carbon cycle (and chemical cycles) and how this feeds back into the climate system.”

  23. August 29, 2017 11:44 am

    It appears that it was a ‘comms failure’.

    Not only was the person tweeting behind the official Met office account unaware that the 28.3C 1990 record was ‘spurious’ but they then went on to give the impression that this was in fact a record set in 1984 and that it had been ‘revised’ with new information. I would say that is a pretty comprehensive comms failure to be honest.

    • August 31, 2017 11:04 am

      It is a pointless record anyway as the date moves every year. Desperate stuff by MO

  24. August 29, 2017 4:11 pm

    I honestly can’t see the point of this record. Since the August bank holiday was moved to the end of the month in 1971 the date has varied from 25th to 31st. What is more notable is that their claimed record falls nearly 6C short of the date record, 33.9C set in 1930 in Rickmansworth. It is almost like they are trying to divert attention away from their summer forecast which suggested a good chance of a very warm season.

    Seems like it would be worth a Freedom of Information Act request to ask for:

    1. Detailed internal rationale for revising the previous “high” downwards

    2. Confirmation if any other “highs” are going to be revised downwards and why – since by definition they are in the past with little potential for “new” scientific measurement based information to come to light, Met Office should be able to audit their data and confirm if they believe it to be correct as of today (and what scientific, measured information would count as “new”)

    3. The internal policy on revising temperature records and the scientific evidence base for doing so, *before* revisions take place. Not the ex post facto justifications.

    Anyone up for it?

    @Mark Tinsely

    Agreed Mark. It sounds like a pairwise analysis was used to discount the
    previous high (i.e. it was ‘homogenized’). How many genuine readings
    are being excised from the record by this method?

    I wonder if the same method was applied to Monday’s temps whether any
    records would be subsequently ‘adjusted’?

    Tony Heller at realclimatescience (love him or loathe him) is exposing a lot
    of issues in the GHCN records (e.g. a large proportion of values are being
    replaced with estimates despite no obvious problems with the real records).

    He also found an apparent excellent correlation (needs checking) between
    CO2 values and temperature adjustments – strongly implying that a climate
    model is being used to ‘correct’ observations.

    • August 30, 2017 11:13 am

      Agreed JohnA. That begs another question: was a pairwise analysis used to *confirm* the 28.2 “record”? Or was that from a single station? It shouldn’t be acceptable to make records from single stations, if reliance on single stations is alsoI/i> the rationale for erasing past records.
