The BoM blah-blahs on – Every station in the metropolitan area recorded its highest January mean temperature on record and most stations (including Sydney Observatory Hill) also broke records for mean maximum and minimum temperatures.
Not a word on the above BoM page of the ever growing urban heat island driving temperatures hotter for 150 years.
I see Richmond RAAF 67105 had Jan 2017 mean max = 34.1, mean min = 20.
I only have to check historic monthly mean max and min for Richmond – UWS Hawkesbury 67021 to find that 1946 equalled the Jan 2017 max of 34.1 and smashed the min by a whole degree. So obviously all the BoM claims for last month are rendered so pathetically tenous and lineball (without plugging in a “correction for UHI”) – what a disgusting propagandist organization the BoM has become.

BoM exaggerates again Canberra hottest January
Claiming Canberra had its hottest January – Hottest January on record sees Canberra’s power usage soar – Canberra Airport 70351 had Jan 2017 mean max 32.8 but Queanbeyan Bowling Club 70072 in 1932 had a Jan mean max of 34.2 –
When you examine site differences, ponder the UHI growth in the ACT – Qbn UHI in 1932 – it looks too close to call. Definitely not a worthy record for the BoM to trumpet.
Perth dams rain data 2016
I am surprised the BoM and the WA Govt Water Corporation have not got their Perth dams rain data in order at the end of 2016. I have several posts on the subject through 2016 and have called for an audit. The latest was WA Water Corporation can not replace a couple of rain gauges in 2 months 27 Oct 2016
Water Corp are still showing the message re faulty instruments. Water Corp monthly rain data individual dams.WA Govt stations in Red

Sydney record hot night – urban heat island never mentioned
Dear old Bureau of Meteorology up to usual tricks claiming a hottest evah record hot night for Sydney but ignoring the UHI. The record is not worth the paper it is printed on due to the huge urban heat island UHI.
Sydney weather: Overnight temperature is record high for December, BOM says 
AWN lets you look around the region and see that the night of the 14th was warmest in the Sydney core stations, Obs Hill 27.1, Airport 27.5, Parramatta 27.5. Note RICHMOND RAAF (067105) at 23.6 further west in the UHI – the record there for Dec is 25 in 2000. The earlier RICHMOND RAAF (067033) 1928-1994 has 25.5 in 1990 as the record Dec night. All pointing to this warm night event being nothing special – unless you want to beat up global warming.

Perth heading for coldest September since at least 1906
Chris Gillham in Perth has been monitoring mean daily temperatures at Perth BoM sites and says Perth Airport 9021 is a shoo-in to have the coldest September mean since opening in 1944. Perth Metro 9225 in Mount Lawley has only been open from Jan 1994 replaced Perth Regional Office 9034 which commenced 1897 and underwent various moves before ending up in East Perth. Progress with temperature updates can be checked at AWN or the BoM.
Chris has a page discussing the history of various Perth weather stations since 1897. I will update as the final numbers are available and hope to include other Perth region sites such as Pearce – Jandakot – Medina etc It is amazing we can have a month like this in the teeth of the vast Perth urban heat island.
BoM max temperature Outlook for September heading for fails
A large percentage of Australia was predicted to have hotter than normal days this month –
as Sep counts down keep a watch on how different areas are trending.
Using the easy to access AWN monthly data it looks as though the following areas will need a late Sep heatwave to avoid the Outlook failing.
For example Tasmania, Adelaide, Ceduna, Alice Springs, Perth, Kalgoorlie region, Giles region, Kimberley, Cape York.
You can also compare with weekly max temp anomalies through this month – which show substantial green or neutral areas. You should be able to see maps for the weeks ending 6th, 13th and 20th Sep.

Perth dam catchments rainfall – how much is that?
It is obvious that BoM and Water Corporation rain stations are low down in catchments near the various dams –
convenient near roads and easy for staff to monitor. Click on Select Using Map – Large areas of the catchments are not monitored by BoM rainfall stations. In 1997 this contour map showed annual average rain for SW WA – the rain numbers would have been heavily influenced by pre 1975 higher level rainfall. It would be helpful if the WA Govt or BoM could redo the map using post-1975 rainfall – which is vastly more relevant to water supply issues than pining after pre-1975 numbers.
The WA Dept of Food & Agriculture have a www site for their own network of weather stations – which in many cases also report to the BoM pages – for example the daily rain maps.
Last week I noticed that the DAFWA station Glen Eagle near the Albany Highway between the Canning and Wungong catchments has recorded the stunning total of 1280mm for the year to date.
Perhaps it is at a higher altitude – will try and find out. GE only commenced in August 2015 – I assume DAFWA checks the calibration of their instruments.
Here is my table of catchment stations with 2016 rain totals updated through August.
The zeros & blanks need urgent attention from the BoM and some monthly totals from Water Corp need examination.
The WA Dept of Water has a large network of stations in the catchments but most seem to be discontinued. Here is a map of their stations – Set Site Category to Meteorological.
I checked a string along the Brookton Highway and none was current – it is time consuming to check. Who knows what useful data they may have. We need all data public to audit and produce a better record of catchment rain.
Example of error in Bureau of Meteorology rain data
On the weekend I noticed this error in the BoM rain map –
I thought come Monday they will correct this to 9.27mm. Here we are Tuesday and no such luck, the error has gone into their daily rain numbers – presumably to be discovered in checks at a later date, weeks months away. It has also gone into 3rd party sites like AWN –
there could be others. It puzzles me that an error as gross as this lives on for 3 days – surely a little robot algorithm could flag outliers way less than this. I thought it was topical in view of my call for an audit of Perth dam catchments rain data.
