MONTHLY CLIMATE SUMMARY - TASMANIA
Record cold May night: At around 6 am on the 30th, the
temperature at Liawenee dropped to -10.5 °C, the lowest value ever
recorded during May in Tasmania. The previous May record was -9.7
°C also at Liawenee in 2001. The lowest temperature ever recorded in
Tasmania is -13 °C at Shannon, Tarraleah and Butlers Gorge in June
1983. Liawenee was not the only cold spot on the 30th, with some other sites also having their coldest-ever May temperature.
Cold nights: Cold nights were prominent throughout the month,
with minimum temperatures below normal on most nights. A number of
sites (including Launceston) had their lowest-ever mean daily minimum temperature,
and for some others (including Hobart and Burnie) the average
overnight temperatures were the lowest they had been for many years.
Cold days: Several sites (including Launceston) had their lowest-ever May mean daily maximum temperature,
and at some others (including Burnie) it was the coldest May since
1968. Averaged across the month, maximum (daytime) temperatures were
about 1 degree below normal on the coasts and 1.5 degrees below normal
inland. Almost all days were colder than normal, apart from the 15th to
19th which was generally warm.
Wet start, dry finish: The first 10 days or so were quite wet across the state, with some heavy falls registered. From the 11th, rain was mostly confined to the western half. Overall, rainfall was close to normal in most areas. It was below normal on the southeast coast, parts of the north and on the upper west coast. Above-normal totals were registered in parts of the southern Midlands, parts of the Derwent Valley and the southwest highlands.
