November - Hobart, Tasmania

A mild and rather dry end to spring. The highest daily rainfall total of 27mm (12th) made up the bulk of the month's rainfall, as a low pressure system over the southern mainland eventually extended over waters to Tasmania's east, giving locally heavy falls to the coast. The remaining 13mm fell throughout the month in dribs and drabs on weak troughs and fronts, and in follow up onshore breezes as high pressure ridged in from the west. Cold enough behind fronts on the 3rd and 26th for a dusting of snow to 700-800m.

Average maximum;  20.5 (+1.6)

Average minimum: 10.8 (+0.9)

Rainfall:  40mm ( average 53mm )

Rain days ( +1mm ):  6/from 13

 

Extremes in daily temperature for November ( records since 1882 ):

Highest maximum:  32.5.....9th ( Record 36.8 in 1937 )

Lowest maximum:  13.0.....2nd ( Record 8.4 in 1885 )

Highest minimum:  15.2.....6th ( Record 19.9 in 1937 )

Lowest minimum:  4.8.....28th  ( Record 0.3 in 1913 )

 

Spring season 2015

This was Hobart's warmest spring in 134 years of records. The mean temperature surpassed the 2014 record by 0.2C and the mean maximum temperature surpassed the 2014 record by 0.3C. Spring rainfall of 80mm ( 48% of average ) was the sixth lowest and the driest since 1972. For Tasmania as a whole it was the driest spring on record and the second warmest.
