Tasmania in October 2017: warm weather arrives

Warm weather was dominant in Tasmania during October, in marked contrast to the cool September. Hobart was among the sites that had their warmest October on record. Rainfall was below average in most parts of the State, with areas in the south and east well below average.

Warm across Tasmania

• Temperatures were well above average across Tasmania both by day and by night, with sites including Hobart, Launceston and Wynyard having their highest October mean temperature on record; there were also records set for highest October mean daily maximum temperature and highest October mean daily minimum temperature
• The mean temperature for Tasmania for October was 1.48 °C above average, the second-warmest October in the 108 years of comparable record
• The mean maximum temperature for the State was 1.80 °C above average (fourth-warmest) and the State's mean minimum temperature 1.17 °C above average (also fourth-warmest)
• Around the 18th, a high pressure system over the Tasman Sea combined with a front approaching from the west to bring very warm over the State, giving a number of sites having their highest October temperature on record and a few their warmest October night on record
• Only one burst of cold air (around the 4th) and two very warm episodes (around the 18th and 28th) meant October's temperatures stood in marked contrast to the very cool September

Rain below average in most areas

• Rainfall was below average for most of Tasmania, with the total 27% below average: the State as a whole received less than half of the rain it did in October last year but more than four times the total from the record dry October 2015
• Totals were well below average (in driest 10% of Octobers) at several sites in the east and southeast; Bicheno had its driest October since 1993
• Rain was close to average over much of the northwest and central north, with several days of moderate rain scattered through the month
