April - Hobart, Tasmania

After a very warm start to autumn temperatures backed off in April but it was still a very mild month. The anomaly was +0.9c compared to the 1981-2010 period ( in brackets below ) or +0.8c above the 1961-90 period. The March anomaly was a massive +1.8c. We have not had a cooler than average month here since November.

Average maximum:  19.2 ( +1.4 )

Average minimum:  9.8 ( +0.4 )

Rainfall:  22mm ( average 51mm )

Rain days (+1mm):  5/from 9

April followed the pattern of March. The first three weeks averaged warm and dry, with strong high pressure over southern Australia, mainly centered to the east of Tasmania. On the 9th, a low pressure system formed over Bass Strait on a front moving in from the west. Onshore winds with moisture from the low brought 8mm, the wettest day of the month. The final week saw a more typical westerly stream with embedded fronts at 36-48hr intervals bringing 2-4mm each time, mostly on the frontal rain band itself. On the 26th, cold air behind the first decent front of the season. Temperatures dropped to single figures during the afternoon, followed by the coldest night of the year, and the first settled snow of the year on the mountain by the next morning - a dusting to near 900m, but this melted away quickly after sunrise.

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

Highest maximum:  25.5.....6th ( record 31.0 in 2014 )

Lowest maximum:  12.6.....26th ( record 7.7 in 1967 )

Highest minimum:  15.2.....9th ( record 18.6 in 1959 )

Lowest minimum:  3.3......27th ( record 0.7 in 1888 )
