TASMANIA'S climate experts are in the grip of a meteorological nail-biter as they wait to see if Hobart has recorded its hottest summer ever.
The Bureau of Meteorology will know at 9am today if summer 2012-2013 will enter the history books as a record-breaking scorcher.
While Hobart recorded its hottest day ever on January 4 of 41.8C, the bureau has to wait until the end of the last day of summer to make a call on the season as a whole.
"It really has come down to the last 24 hours of the season," bureau climatologist Ian Barnes-Keoghan said yesterday as the temperature sat at a very cool 15C at noon in Tasmania's capital.
"We are sitting just on a record as we speak but we have to wait to see what happens during the rest of the day and overnight before we can call it.
"Whatever happens, we know it has been a hot, dry summer overall."
Hobart recorded nine days over 30C this summer.
Tasmanians got their first taste of autumn on Wednesday when the overnight temperature fell to 10.9C just after 5am.
Already firewood merchants are reporting early orders are coming in.
Mr Barnes-Keoghan said long-range forecasts indicated Tasmania would experience a cooler autumn than usual.
But more high temperatures later this week and next should gently ease Tasmanians into the cold reality that summer is now over.
The bureau has forecast temperatures of 23C for Saturday, 26C on Sunday, 29C on Monday and 30C on Tuesday.
Cooler temperatures are then forecast for the rest of the week.
"The system still has the ability to throw hot weather at us at this time of year," Mr Barnes-Keoghan said.
Recent rain has been welcomed by farmers and gardeners after a summer when Hobart received less than half its average January-February rainfall.
The average rainfall for Hobart from January 1 to the end of February is 88.1mm. This year less than 40mm fell in that time frame.
The period was the driest on record since 2002 when only 26.8 fell all summer.
