Really strange misinformation – the facts are very simple – Canberra is having a record run of cold nights for this early in June. Yet today the ABC reports – Canberra’s extreme run of overnight lows ‘only seen every 10 to 15 years’ – What is the BoM smoking. Yesterday the Canberra Times quotes the BoM to write – Canberra weather: Cold, frosty mornings to continue before a warm long weekend – Same style of obfuscation – avoid admitting a record at all costs. The Fairfax article confuses Monday and Tuesday – talks of warm weather to come. And there is this odd mention of last August that has nothing to do with anything. Weird mention of “every 10 to 15 years” – no it is the coldest run of nights this early in June for 76 years!!! Then they throw in El Nino to appear all-wise. And our national policy is affected by the org generating this evasive twaddle.
Here is a Table of sorted June minimums for Canberra down past minus 5.1. The record to break is – Tuesday the 2nd -7.0, Wednesday the 3rd -5.1, Thursday the 4th -6.9, all time record run of cold minimums this early in June. Case closed.

Are readers checking how the much prophesized El Nino is travelling ?
Remember on 12th May 2015 the Bureau of Meteorology BoM suddenly called an El Nino as being on for 2015. I thought at the time it was a sudden jumping on board the El Nino express for the BoM in the wake of NOAA’s earlier determination to have an El Nino. We have heard various newsmakers and groups Cut open the sachet and squeeze out the content in your mouth. Ashwagandha roots when used regularly helps to improve tadalafil pharmacy online the capacity to hold longer. Generally people do not want to disclose about this particular problem to anybody and especially to the doctor to get an alternative medicines to treat erectile dysfunction. viagra wholesale india This is because excessive intake of the medicine cheap levitra energyhealingforeveryone.com results in side effects and infections. calling for an El Nino over 16 months now.
Anyway – take a look at the SOI – which has been rising since 26th May. And am I seeing easterly winds here.
Lets just say it is a sputtering start if a real El Nino is to develop.
I am not predicting anything – just pointing out real world data –
Canberra just smashes coldest night record for this early in June – 75 years of data from 1939
At least -6.5°C this morning – we will see official figure later – In 1987 both the 1st and 2nd June read -5.1 which was the previous record. In the face of the growing Canberra urban heat island UHI.
Coldest April night record broken twice in Hughenden and Maryborough in Queensland – various cold night records scattered across Australia through May too
The Courier Mail reported 22nd April – Several Queensland towns hit record low April temperatures.
Hughenden Airport broke the coldest night record including the Post Office – on the 22nd April – and then broke that again on the 27th.
Maryborough saw the same pattern with 6.2°C on 22nd and 5.5 on the 27th both breaking the previous record from 1966. Clermont Airport broke the Post Office record with 4.3 on the 27th – the Post office saw 4.6 in April 1999.
On April 30th Kulgera in southern NT had a record April low of 1.5.
Alice Springs on 1st May hit 1.6 making it the coldest 1st of May since 1881 or whenever the Post Office commenced.
On the 14th Eyre in WA hit -2.5 a record low.
The Courier Mail reports on the 14th – Brisbane wakes up to chilly morning as southerly change pushes dry air and cold winds –
On the 15th Tamworth AP read -4.5 a record low.
On the 16th Broome AP read 7.7 an equal record low.
On the 16th West Roebuck (near Broome) read 5 smashing the previous record of 7.
On the 16th Marble Bar read 7.5 smashing the previous record of 9.4.
On the 25th Newman AP daily max 14.7 smashing the previous record of 16.
Imagine the BoM media releases if the above were all warm April & May records.
If anybody knows of other records – comment or email them – thanks.
Greens ask the BoM Director Dorothy Dix questions at Senate estimates hearing which highlights that no MP’s have the guts to ask the BoM serious questions
The Canberra Times has this story – Bureau of Meteorology rejects Maurice Newman’s climate claims – recounting how Greens Senator Larissa Waters lobs the BoM Director Vertessy a series of Dorothy Dix questions that he can bat away.
It is truly disgusting that no MP ever questions the BoM in depth on for example say the ACORN adjusted temperature data.
Example where the Australian Bureau of Meteorology is told about a fault in rain recording but in two years fail to correct their data
I was told by a reader about a loss of ~18mm rain recorded at Montague Island Lighthouse 69017 (NSW south coast near Narooma) on 6/7th April 2013. I checked this out and sure enough the 30 minute data shows 20.6mm at 2.30am on the 7th which at 3am is reset to 2.2mm – so 18.4mm of rain was lost in what must have been an electrical/electronic fault. I kept the www page of 30 minute data.
I sent the following fax to BoM Sydney on 9 May 2013 and never got a reply.
[MONTAGUE ISLAND LIGHTHOUSE ID: 069017 Rainfall 7 April 2013
Dear Manager,
Your webpage “Latest Weather Observations for Montague Island”
www.bom.gov.au/products/IDN60801/IDN60801.94939.shtml
records around 18.8mm rain ~10.30am to 11am on Saturday 6th April.
There was another 1.6mm recorded ~9.30-10pm that evening making 20.4mm.
A further 0.2mm made the total 20.6mm around midnight.
Then at 3am on the 7th the rain total reset to 2.2mm which was the 9am total recorded.
You can check the Canberra radar archive at –
www.oscilmet.com.au
and there were rain signatures at “~10.30am to 11am on Saturday 6th April” and
“~9.30-10pm that evening”.
So perhaps your Montague Island telemetry has lost 18.4mm of rain in the signal somewhere.
All the best,]
Checking daily rain for station 069017 at Climate Data Online we see that 2.2mm is recorded for the 7th April 2013 –
What would it take to get the BoM to correct an error ?
Why can’t the BoM decide on Canberra official temperatures in four days ?
This puzzles me – here we are Sunday morning the 24th May and the BoM can not settle on the maximum for the previous Tuesday and the minimum for Wednesday.
Odd.
Evidence of urban heat island (UHI) at Cobar, New South Wales, Australia
The BoM Cobar Meteorological Office is adjoining housing on the north edge of Cobar, a mining and pastoral town in remote New South Wales population ~4,000. A BoM MO is professionally staffed.
The Airport is several km away to the SW – these minimum temperature readings for May show a UHI of a few degrees most mornings. 
Obviously if mornings are too breezy – the relationship gets perturbed. You can see here that lately there are only light zephyrs in the early mornings when minimum temperatures are recorded.
The BoM classifies Cobar MO as “non-urban” – despite housing a stones throw away. Not on this planet.
Dubious BoM claim about Brisbane rainfall – “Wettest May day in 175 years” – thats the 2nd of May 2015
Fairfax are running this story Brisbane weather: Wettest May day in 175 years
The claim that 182.6mm on the 2nd May represents the “Wettest May day in 175 years” is not even technically clean because many early years had no data – so the 175 years is shonky. But let’s ignore that. Facts are that rain data are so noisy that any claims based on one station need examining. In this case on 2nd May 2015 for the BoM’s own rain district 40 South Coast Moreton & Brisbane.
These stations exceeded the 182.6mm figure. I have tried to avoid the higher altitude stations which have heavier falls.

Let’s look at a four day period 2nd to 5th May 1996 – there may be others but my time is limited –
I think by any standards the 2nd to 5th May 1996 swamps any record claimed from 2nd May 2015. Count some of the 4 day totals.
Australian Bureau of Meteorology claims Caboolture rainfall is “off the scale” – yet their own maps show higher daily totals in May 2009
Fairfax media reports – Brisbane weather: ‘An extreme weather event’ takes five lives – The ABC reports – Queensland weather: Five people killed after three cars swept away by floodwaters; storm moves into northern NSW –
A BoM contour map shows the rainfall to 9am on 2nd May – this map is for 20 May 2009 – note the higher rain contouring into the purple zone.
The 7th, 8th and 9th of May 1980 had heavy rain in the Brisbane region too. Note I have only scanned for May rain – there would be many more floods if I looked at all months.
I have not yet seen numbers convincing me that the last couple of days was worse than 2009 – and daily data is very poor for the earlier in the 20th Century.
There are many more rain gauges now but data is not easy to access. This AWN site is useful for eyeballing daily rain at the many Brisbane region stations. Here are the rain maps from above BoM links to compare for yourself –

Purple is above 200mm per day
Dark blue is 150-200
Light blue 100-150.
Obviously the station data is more spotty than the contour maps – and BoM computing has to somehow average to get the contour positions.
