The Wacky World of Weather Stations: No. 255- Cape Otway (Vic)

Tuesday 26/11/2019

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: Cape Otway Lighthouse 90015

Opened: 1861

Daily Temperature data from: 1864

Data used to adjust Acorn sites at: Butlers Gorge (Tas.-1956), Cape Bruny (Tas.- 1991), Melbourne (1964), Mt Gambier (1950), Wilsons Promontory.

Location:   Co-ordinates  -38.8556 143.5128

170km south-west of Melbourne.

BOM site plan 2016:

Google street view 2018 (photo by Carl O’Donoghue):

An Acorn station, and a very long record from 1864. But the screen is 9 metres from the house and 15 metres from the bitumen road. Before 2011 the screen was close to the scrub, with a hut close by as well.

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

FAIL

Percentage of all Australian sites not compliant: 35.22%.

    Hi Ken let’s hope that this does not remain in moderation like some other comments of mine !
    1 : The BOM weather station is 83 meters above sea level. The slope down to the sea from the light house area is steep with cliffs. I know this because I’ve visited Cape Otway.
    2: Thus all heavy cold air will fall away from the BOM screen with the result that minimum temperatures will be higher than nearby towns like Apollo Bay or Colac or Lorne or even Geelong, the nearest big city.
    ( We saw the same problem on Cape Willoughby on Kangaroo Island SA a week ago )

    3: And yes it is also a FAILED station for the reasons you mention anyway.

    I’m very surprised that the BOM use the observations from this Cape Otway station to adjust ACORN sites at: Butlers Gorge (Tas.-1956), Cape Bruny (Tas.- 1991), Melbourne (1964), Mt Gambier (1950), Wilsons Promontory.

    Perhaps they should rename the Acorn set as the pumpkin set?
    It requires magic to operate.
