It’s not just happening in Australia.

Recorded temperatures at the Bureau­ of Meteorology’s Thredbo Top automatic weather station have dropped below -10C in the past week, after action was taken to make the facility “fit for ­purpose”.
A record of the Thredbo Top station for 3am on Wednesday shows a temperature reading of -10.6C. This compares with the BoM’s monthly highlights for June and July, both showing a low of -9.6C.

The BoM said it had taken immed­iate action to replace the Thredbo station after concerns were raised that very low temperatures were not making it onto the official record. Controversy has dogged the bureau’s automatic weather station network since Goulburn man Lance Pigeon saw a -10.4C reading on the BoM’s website on July 2 automatically adjust to -10C, then disappear.

Later independent monitoring of the Thredbo Top station by scientist Jennifer Marohasy showed a recording of -10.6C vanish from the record.
