The Wacky World of Weather Stations: No. 185- Bridgetown (WA)

Tuesday 29/10/2019

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: Bridgetown 9617

Opened: 1997

Daily Temperature data from: 1998

Data used to adjust Acorn sites at: —-

Location:   Co-ordinates  -33.9486 116.1311

225km south of Perth.

BOM site plan 2018:

Google satellite image 2019:

This station, part of the Acorn network, appears to be in an ideal site- rural, far from any UHI, surrounded by open paddocks, and well exposed. The only disturbance outside the enclosure is from where hay has been fed to livestock. All in all, a perfect site. But…..

Photograph September 2015:

Like many other stations which are visited only once a year, it is subject to neglect. The enclosure in 2015 was overgrown with weeds and grass to about 0.5 to 0.6 metres (and in some parts much taller)- definitely not kept trimmed to a few centimetres. Is this a regular occurrence?

This Acorn station is non-compliant, with temperatures reported at Latest Weather Observations but not used to adjust data at other Acorn sites.


Percentage of all Australian sites not compliant: 25.55%.

    “with temperatures reported at Latest Weather Observations but not used to adjust data at other Acorn sites” – from that can we deduce that the readings aren’t showing any warming?.

    Ken, some folks will think we are nit picking here. It’s just grass they will say. Grass growing is natural.

    The BOM’s own guidelines say that the grass must be kept to just a ‘few centimeters’.

    But there is no explanation of why that needs to be so. So maybe an explanation is needed ?

    How does grass growing this high affect the temperature recorded by the thermometer ?
