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
The three worst BoM stations. BoM stations in Blue.
Mundaring Weir daily rain 2016 no data post March
Victoria Dam daily rain 2016 data shambles
Serpentine Main Dam daily rain 2016 no data post May
Well for a start it was wet. More later as temperature data updates. Temperature anomaly maps show the second half of the year was cooler than the first half.
The six month max anomaly map is updating to 31st Dec the 12 month map is warmer showing how temperature anomalies over Australia tended to cool in the second half of 2016.
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.
When you hear all the yakka on TV about heatwaves, hottest this or that, hottest bushfire since?? – remember they seldom tell you most of us had plenty of winter rain, we had a cool & wet September – then a cool October now followed by a moderate November. And why is it news that summer is starting on time.
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.
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.
Just ran an update as at 31 July – several Water Corporation stations look suspect – several BoM stations are out of date by months. My spreadsheet showing audit required.Source of BoM data and map – for a years daily data enter the 6 digit BoM station ID alongside Station number then click the Get Data button.

In May I reported – West Australian Govt Water Corporation fails to record March 2016 rain at several dams
This animation for the 12th to 15th July 2016 shows a cool anomaly which moves from northern WA into the NT then into Qld.
You can see daily temps by clicking on districts at this AWN map. BoM “Climate statistics for Australian locations” give you the existing record. Change stations by changing station # in URL. To see the seven records I noted Continue reading
