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.

The Eddystone light house is a very windy place Ken.
But all that 3 meter high scrub very effectively shelters the BOM weather station from these winds.
The station is also perched high up on a bluff along with the light house so ships at sea can see the light warning of this dangerous hazard to shipping.
So colder air being heavy will tend to fall away from the screen to the sea & beaches.
This means that it is not accurately measuring local the minimum temperatures over time.
Not compliant with BOM’s own guidelines !
So why is data from this station used to adjust the Launceston airport observations ?
