quote from Ben ” 6th March 2019
Today’s taste of wintry weather comes less than a week after the state endured a day of record-breaking March heat.
Dover’s 40.1 degrees on Sunday was the first time on record any location in Tasmania has exceeded 40 degrees during March.
Eight other weather stations, including Hobart (39.1C), also beat Tasmania’s previous March maximum temperature record of 38.0 degrees on Sunday.
Impressively, Hobart’s 39.1 degrees on Sunday was also hotter than any day in the city during summer. Last season’s highest temperature was 37.9 degrees.
Sunday’s heat now seems like a distant memory, as much colder southwesterly winds flow over the state today.
Hobart was only sitting on 13 degrees at 10am, although wind chill was making it feel more like eight degrees.”
