The Wacky World of Weather Stations: No. 172- Geraldton Airport (WA)

Thursday 24/10/2019

Please refer back to my first post for site specifications and to No. 92- Logan City for 2018 specifications.  If you wish to check on this (or any) site for yourself, go to my post on how to check for yourself.

Station: Geraldton Airport 8315

Opened: 2011

Daily Temperature data from: 2011

Data used to adjust Acorn sites at: —.

Location:   Co-ordinates  -28.8047 114.6989

375km north of Perth.

BOM site plan 2016:

Google satellite image 2019:

Google street view 2015:

Again we see an instrument area at an airport on an artificial mound above the level of the surrounds. On still nights this will result in cold air draining away from the site causing warmer than expected minima. As well, the screen is 25 metres from a large expanse of cultivation which will range from bare soil through green growing crop to dry mature crop about 0.5 metre high.

This station is non-compliant, with temperatures reported at Latest Weather Observations and used to adjust data at Acorn sites.


Percentage of all Australian sites not compliant: 23.76%.

    Ken I am perplexed by this one : It the BOM weather station on a mound above the surrounding area ?
    Or is the a raised bund there marking out the BOM site area ?

    The satellite image does not help. And the land photo doesn’t either..


    Of course if there is an earth bund all around the site, then this station is NOT compliant with BOM’s guidelines either.

    The site plan says (bit small to read): “instrument enclosure on raised levelled dirt pad 0.5 – 1.0m above surrounding ground.” Not as high as Townsville or Rocky, but still raised causing cooler air to flow away.

    Thanks for the clarification Ken. Mt Barker BOM also comes to mind.

    I’ve a mind to take some more photos of Mt Barker. Just to see if any changes have happened. There were none 3 weeks ago when I walked past…But then I spoke to Paul Lainio from BOM Adelaide office. Maybe he arranged to try & make it compliant.
