On page 10 of 23 the BoM “Special Climate Statement 43 – extreme heat in January 2013” – Updated 1 February 2013 – says –
“2.5 Monthly mean temperatures for January
January 2013 was Australia’s hottest month on record. Averaged nationally, the
maximum temperature was 36.92°C, 2.28°C above the 1961-1990 average, and 0.11°C above the previous record of 36.81°C, set in January 1932. The monthly mean
temperature (day and night combined) also set a record. It was 29.68°C, 1.77°C above the 1961-1990 average and 0.27°C above the previous record of 29.41°C, also set in January 1932.”

Perth summers (Dec-Jan-Feb) as measured at Perth Metro in Mount Lawley looked too warm for 2012 and 2013 when compared with Perth Airport 09021. The differences for summer mean max between the Airport and the old Regional office (1898-1992) going back to 1945 and Perth Metro 1994-2013 show that 2012 and 2013 fall clearly outside a long established band.

I noticed there were instrument changes at Perth Metro in July 2011 – not sure if they were the instruments that read the daily max. I checked Perth Airport summers against Pearce RAAF 1994-2013 and all differences fell in a band – which also suggests that Perth Metro is faulty.
Anybody reading our media just now will find plenty of articles from the BoM spruiking the “hottest summer ever” for Australia.

A week ago I posted – February not turning out stellar hot so far – Weatherzone prediction fall flat on face so far – 6.8° out for Sydney
The SMH article of 4 Feb 2013 “Cool spell soon to be broken” – has the following quotes from Dr Dutschke of Weatherzone (a Joint Venture between the BoM and Fairfax).
[Beyond this week, more heat can be expected with weather models point to a hotter spell by mid- to late-February, Weatherzone’s Dr Dutschke said.
Sydney, Adelaide and Melbourne could all see temperatures of 40 degrees from that second heatwave, he said.]
BoM forecasts out to 23 Feb – no heatwaves being forecast yet – but hey it is summer.

Still waiting to see any sign of your prediction coming to pass Dr Dutschke.

A week ago there was this article in that paragon of reliable information – The Sydney Morning Herald – Cool spell soon to be broken – phew now we can not enjoy a few cooler days without the Fairfax owned Weatherzone big-noting their colossal forecasting skills. – The 4 Feb SMH article says – “Saturday may see Sydney’s “best chance” of temperatures above 35 degrees, with more scorching weather set for western suburbs and inland towns…”.
Well Saturday reached 28.2 in Sydney not 35.
I am curious what readers are noticing in their areas – apart from Perth is there any unusual heat around ?
My point in this is that it is summer – some heat is to be expected – we know there may be hot spells in February – we can check the BoM standard forecasts.
They tell us this for the next week – a tough week ahead for the “heatwave spruikers”.

You could not invent this. See my post from yesterday – now as Chris Gillham has pointed out – the BoM mistakenly entered 36.9° as 39.6° – and nobody had the nous to question this for a week. The Weatherzone announcement – Mackay sets January heat record –
was dated 5 Feb as was the ABC’s. So the media announcing this triumph of warming was a week after the instruments at Mackay Aero recorded 36.9 which somehow ended up as 39.6 in BoM data for a week. The 36.9 is still a record for Mackay Aero which has a short record, previous high was 35.8 on 7 Jan 2006 – but Mackay M.O. See more articles like How to Keep Men Away From Prostatitis?

To be correct the media stories should have said – “Mackay Airport sets January heat record” – and then the article could have stated that Mackay M.O. recorded 37.2 on 1st Jan 1985 when apparently there was no Airport data that we know of.
I wonder what will happen now – will the BoM or either media group be interested in publishing a correction ?

A reader sent in this news item – Mackay sets January heat record – quoting the Bureau of Meteorology saying “Mackay has set a new record for its hottest January maximum temperature. The weather bureau’s Jeff Sabburg says the mercury hit 39.6 degrees on January 28.”
To understand how dodgy this claim is – there are two BoM recording stations current at Mackay.
Mackay M.O. station 033119 (MO = Met. Office) with data from 1960 and the other is Mackay Aero station 033045 at the airport with a decade of data in the 1950’s then a 30 odd years gap to 1996.
The hottest Jan day claim for the 28th was fom Mackay Aero – there was no hot Jan day record at Mackay M.O. the BoM purpose built official meteorological station for Mackay which had longer continous data than Mackay Aero.

See comment 5 for update 2 Feb.
Classic bait and switch publicity today by the BoM to cover up a monster FAIL. – Giant heatwave delivers hottest January on record – Readers must understand that after months of talking 95% about maximum DAYTIME temperatures to beat-up their heatwave propaganda, the BoM is today talking “…the average of maximum and minimum temperatures for the month was 29.7 degrees.” A very different metric to the daily max temperatures the BoM has been beating up for months – the BoM is totally opportunistic when it comes to feeding the media heatwave propaganda – shifting goalposts is easy for them.

Here is a BoM chart showing the 1932 January max anomaly record that has NOT been broken this month.

I have already posted on this article – Records topple, city stumbles as gauge hits 46C – in The Australian Saturday 19 Jan 2013 – I focussed then on Sydney and the near less urban stations. However The Australian gives a clear impression in their opening text that heat records were broken across NSW on the 18th Jan 2013.
[SYDNEY’S city centre was hotter than Bourke in the northwest of the state yesterday as decades-old heat records tumbled across NSW, stung by a stubborn mass of heated air moving from the centre of the country. The city recorded its hottest day since records were kept as the temperature hit 46C.]
What deceptive nonsense – the impression created by the words “…decades-old heat records tumbled across NSW…”, is that 18 Jan 2013 was also a record hot day at country centres. This is not borne out by the facts.
Lets us take this graphic from The Australian 18 Jan 2013. I have left the copy on the left untouched and on the right have added in black under “18 Jan corr” the correct maximum for the 18th Jan 2013. Then in red I have added the max on 11 Jan 1939 if available – stations below Ivanhoe were discussed in my previous article.

Starting with Bourke which was hotter on the 12 & 13th Jan (48.3 & 48) – obviously no record there on the 18th – and 11 Jan 1939 was 117F or 47.2 – it was 48.3 on 10 Jan 1939.
Griffith was hotter on the 5th & 6th Jan (44.7 & 44.3) obviously no record there on the 18th – and 11 Jan 1939 was 116F or 46.6.
Wagga Wagga was 44.1 on the 18th Jan but felt 117F or 47.2 on 11 Jan 1939.
Ivanhoe recorded 44.9 on the 18th but had hotter days on 5th, 6th & 7th Jan (46.7, 46.4, 45.3) obviously no record there on the 18th – and 11 Jan 1939 was 120F or 48.9.
How does The Australian come to publish the clanger errors for 18 Jan 2013 ? Knowing that January 1939 was hot in Sydney – why not do the stand-out obvious thing and run some checks on NSW sites for Jan 1939 ?

Lets be real – after two cool summers – summer 2010-11 and summer 2011-12 – you can not blame the Australian Bureau of Meteorology for hyperventilating about the heatwaves sweeping Australia this summer. They have published SPECIAL CLIMATE STATEMENT 43 – INTERIM Extreme January heat update 14 January, 2013. If you go to Table 1 on page 4 – part screen shot below.

You see that on the 9th 12046 Leonora (at the Post Office) hit 49°C an all-time daily max record – the ONLY record-breaking site in Australia on the 9th. Now there is another nearby station 12241 Leonora Aero and in the screenshot below you can see the daily readings for the two sites.

Digging deeper into the station details – click on the icon map of Australia in top right here – then scroll down and take the link – A basic site summary is available in a pdf document. Readings this pdf of Basic Climatological Station Metadata we find a series of sketch maps of the instruments surroundings starting in 1998. The latest map is on page 4 and we find that between 2003 and 2008 a junkyard has developed in close proximity to the instruments.

Note that the 1.6m & 1.8m solid fences have also increasingly boxed in the instruments. All part of micro-site effects contributing to creeping urbanization. All contrary to the international standards for weather instrument exposures. But no barrier to the BoM claiming another record.
