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: Cape Naturaliste 9519

Opened: 1903

Daily Temperature data from: 1957

Data used to adjust Acorn sites at: Cape Leeuwin.

Location:   Co-ordinates  -33.5372 115.0189

193km south-west of Perth.

Google satellite image 2019:

Here is a street view photo taken by Patrick Cheah in March 2018:

“Street” view 2018:

The screen is only a couple of metres away from scrub to 2 metres, and closer to scrub to 0.8 metres. It is not sufficiently exposed.

Update 05/11/2019:

Here is a photo taken yesterday (04/11/2019) by reader Brian, showing how close the screen is to vegetation:

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: 25.97%.

    Ummmmm ? Now where is that Al bloke ? Maybe he can provide us with a link to a more recent satellite photo on Google Earth Pro, showing that the BOM has cleared away the native scrub around the weather station ?

    Meanwhile free, plain old ‘Google Earth’ showed me that there are native shrubs growing right up to the Stevenson screen. No date on the photo unfortunately.

    But whatever the date, it’s clear that BOM has in the past allowed this weather station to be NON- COMPLIANT..

    So how can anyone rely on the temperature observations recorded at this site ?

    I failed to note Patrick Cheah’s ‘street view’ photo of March 2018.
    Somewhere in the scrub is the Stevenson screen !

    ‘Cape Naturaliste’ is a very exposed place with lots of wind and salt spray to limit the growth of native vegetation. Two meters is about as high as the native scrub gets except in sheltered gullies, with less height on elevated spots.

    It follows that the native scrub has not been cleared around the BOM weather station for a number of years. And thus it has been non compliant for a number of years as well.
