worst floods both occurred in Autumn. City minimums range from in May, and up to in March. High temperatures during Autumn range from in May up to in March. Winter On average, wintertime lows dip down to in July, while daytime highs range from in July up to in August. Winter is typically the season with the least amount of wind, although the increased occurrence of cold frontal systems during the cooler months have helped cause wind gusts of up to 113 km/h - in the winters of 1949 and 1984 at Launceston Airport, 14.8 km away from Ti Tree Bend. This passage of cold frontal systems are responsible for winter being Launceston's and the rest of northern and western Tasmania's wettest season. Spring Spring is mostly a transition from winter to summer. Cold weather reaches Tasmania less often and temperatures slowly begin to rise. Snowfalls, although rare, have been recorded in Launceston's surrounding areas as late as October, during 1940, 1978, 2003 and 2020. The month of October experiences the greatest rise in temperatures. 2009 Southeastern Australia heat wave The 2009 southeastern Australia heat wave was a heat wave that commenced in late January and led to record-breaking prolonged high temperatures in the region. During the heat wave, 50 separate locations across Australia set various records for consecutive, highest daytime and overnight temperatures. The exceptional heat wave was caused by a slow moving high-pressure system that settled over the Tasman Sea, with a combination of an intense tropical low located off the North West Australian coast and a monsoon trough over Northern Australia, which produced ideal conditions for hot tropical air to be directed down over Southeastern Australia. The heat began in South Australia on 25 January but became more widespread over southeast Australia by 27 January. A weak cool change moved over the southern coastal areas bringing some relief on 30 January; in Melbourne the change arrived on the evening and dropped temperatures to an average of . Higher temperatures returned on the following weekend with Melbourne recording its hottest day since records began in 1855: , also the hottest temperature ever recorded in an Australian capital city. During the heat wave, several records were broken; Tasmania recorded its highest ever temperature; in Scamander, and the long-standing Tasmanian record of (recorded in Hobart on 4 January 1976) was broken five times within two days at Flinders Island, Fingal
