Tasmania's March weather was mild overall, with Dover's 40.1 degrees in March 2 the hottest March day ever recorded in the state.

That temperature was well above the previous record of 38.0 degrees, which was set at Campania in March 2008, Bureau of Meteorology Tasmania climatologist Ian Barnes-Keoghan said.

"Most of the records were down in the South-East, but Launceston also managed to have a record high temperature for March, although only 33.5 degrees, compared to a previous record of around 33 degrees," Mr Barnes-Keoghan said.

However, by the end of the month we were rugging up.

A cold change on March 25 brought two days of temperatures below 15 degrees, with strong and damaging winds, snow and cold mornings, and another front on March 29 brought more cool weather.

"One of the big things many Tasmanians will remember is how cold Tasmania has been over the past week; there's been lots of cold fronts coming through," he said.

"But people might have forgotten that we had record high temperatures at the beginning of the month. So overall, even though the end of the month has been fairly cool, March was generally a mild month for pretty much the whole state."

Rainfall was close to average for most of the state, but the state's North and East Coast were below average.

"Unfortunately the North and the East Coast continue to be relatively dry and the far North-East managed to get very little rain, so overall below average rain for the North and the East," Mr Barnes-Keoghan said.

Cold fronts coming through the state in the second half of March meant "reasonable" rainfall that was close to average through the West, central parts of Tasmania and in the far South.

Averaged over March, Tasmania's maximum temperatures were 0.85 degrees above average, with minimum temperatures 0.42 degrees above average.

The overall mean temperature was 0.64 degrees above average, which was warmer than March 2018, but cooler than March 2017.

Tasmania's total rainfall for March was about 22 per cent below average, which was drier than March 2018, but wetter than March 2017.

"Building on the very dry January that we've had though means ... it's started out as the driest start to the year since 2006," he said.

There is no strong signal either way for a wet or dry autumn, "but the West and the North tend to get most of their rain during the cool part of the year, so rainfall [is] tending to increase".

While the weather outlook suggests a warmer than average autumn, the days are definitely cooling, Mr Barnes-Keoghan said.

"This is the time when temperatures really start cooling off and the days start getting much shorter."
