LAUNCESTON is forecast to record its highest summer temperature in four years next week.
If the mercury hits 34 degrees on Wednesday, it will be the hottest summer temperature since the record of 39 degrees on January 30, 2009.
However, it will be nowhere near the statewide record of 42.2 degrees, set at Scamander, also on January 30, 2009.
The Ti Tree Bend weather station also expects to record seven consecutive days of at least 27 degrees from today.
The last time this happened in January was at the now closed Launceston Elphin weather station, from January 25 to 31, in 1974.
However, the January record, of eight consecutive days of at least 27 degrees, was set at the Launceston City weather station, now closed, from January 20 to 27, in 1918.
Bureau of Meteorology climatologist Lorien Martin said that the all-time record, irrespective of month, across all three relevant Launceston weather stations, was set at the city site in 1898.
In that year, there were 14 consecutive days of at least 27 degrees from January 25 to February 7.
Ms Martin said the most recent run of a significant number of consecutive days of at least 27 degrees was last year.
From March 4 to 12, there were nine consecutive days of at least 27 degrees, including eight days in a row of at least 30 degrees.
Ms Martin said that the March 2013 hot weather run was a significant event in terms of high temperatures.
