Summer looks unpredictable, with the BOM unable to foresee any extremes for Tasmania.

Bureau climatologist Ian Barnes-Keoghan said the North experienced an unusually dry spring.

‘‘Lots of places would have had their warmest spring on record,’’ he said.

Launceston recorded a new mean daily maximum temperature of 19.6 degrees, with the previous record of 19.3 set in 1987.

Launceston recorded a low total spring rainfall of 63.5mm, 38 per cent of the spring average of 166.5mm.

‘‘Looking into summer, the signals are a bit mixed – normally, particularly for the North, it’s the driest time of year, but what we’re seeing is not a strong push one way or the other towards wet or dry, and not a particularly strong push towards warm or cool,’’ Mr Barnes-Keoghan said.

‘‘The full range of things we’ve seen in summers in the past is possible for this year.’’

Despite snow being forecast for peaks on Wednesday, Mr Barnes-Keoghan said summer weather arrived early this year.

‘‘Getting snow on individual days, ‘it happens’ is probably the best way of describing it; weather can be very variable in Tasmania at any time of year,’’ he said.

‘‘In some ways, summer got off to quite an early start because October was so terribly mild; through parts of Tasmania during spring there were temperatures more typical of summer.’’

Globally, the UN’s World Meteorological Organisation predicts that 2015 will be the hottest year on record, the result of global warming and the El Nino.
