Frosts reports 2020

[Chris Raine]

Noticed at Thornbury Southland that lowest ground temp so far this year is -1.4C with no air frost yet Normally would have had light air frost by now

Thanks for the frost news and updates, gentlemen. Much appreciated.

Interesting to see in these 'warm' times that a record low minimum can be set. How long is the record at Christchurch Airport? The Wikipedia pages says 1943 (so, 77 years) and that the previous record low for March was -0.2°C, so the record was well beaten.

Temp records for Chch Aero only go back to Sep 1953, and yes, -0.2C in 1990 was its previous March record. The City Council's Chch Gardens site in Hagley Park has records going back to 1905, but it's generally a little warmer than the airport and has never recorded an air-frost in March before (don't have last month's figures yet though).

...sorry to be off topic(Cant transfer this to the Corona-virus, Coved 19 topic) but it could have something to do with respiratory problems that people have with pollution in large cities like Wuhan, Milan, Madrid. New York,etc.,especially during the winter time, resulting in breathlessness, like what one of the symptoms that this virus has?

Not in this household, Tony.
