August - Hobart, Tasmania

Like July this was a fairly cold month, mostly due to low overnight temperatures. The mean temperature anomaly was -0.7c below 1981-10 ( in brackets below ) or -0.3c below 1961-90. It is the first time since 2011 any two months in a row have been colder than the 1961-90 period.

Average maximum:  13.3 ( -0.4 )

Average minimum:  4.6 ( -1.1 )

Rainfall:  65mm ( average 53mm )

Rain days ( +1mm ):  14/from 20  

Dry at first with local frost, severe away from the coast, then a variable month with regular fronts preceeded by mild air from the continent. This was the first month since January to have above average rainfall in a year that is running with a modest rainfall deficiency. The wettest day this month was 19mm in frontal convergence. This was not a significant month for snow in the Hobart area, and there was no snow in the higher suburbs ( <300m ), which usually happens in most August months. Snow line of near 1200m on the 10th, 800m on the 12th&17th, near 500m on the 18th, 700-800m on the 27th&30th. All light falls or dustings.

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

Highest maximum:  18.1.....10th ( record 24.5 in 1977 )

Lowest maximum:  9.1.....18th&27th ( record 5.5 in 1974 )

Highest minimum:  9.8.....26th ( record 15.0 in 2005 )

Lowest minimum:  1.0.....3rd&20th ( record -1.8 in 1962 )
