Tasmania in July 2017: Cold nights, dry in the east

Cold weather was common in Tasmania during July, with several especially cold overnight temperatures. Rainfall totals were close to average for much of the State, but it was another month of below-average rain in the east and rainfall was above average on King Island.

Rainfall below average in the east

• Rainfall was once again below average in the east of Tasmania, and especially near the East Coast: Bicheno reported just 7.8 mm for the month (its driest July since 1997), after having only 0.5 mm in June
• Totals on King Island were very much above average: King Island Airport had seven days with more than 10 mm, about double the July average for such wet days
• Rainfall was close to average over most of the rest of Tasmania; the State total rainfall was 12% below average
• There were a number of rainfall events during the month, most notably when low pressure systems were near the State around the 4th and 18th and when cold fronts crossed on the 14th and 23rd.
• It was wetter than the very dry June

Cold nights and cool days

• For most of Tasmania July was one or two degrees cooler than June
• Very low overnight temperatures and localised frosts were common during the month; several inland locations experienced long runs of nights below freezing and Liawenee dipped to −10.4 °C on the 3rd
• Lake St Clair and Ross – sites with relatively short record – had their lowest temperature on record
• Tasmania's mean minimum temperature for July was 0.59 °C below average, making it the coldest since 2008
• A few sites had their lowest July mean daily minimum temperature on record and several others (including Hobart and Launceston) had their lowest mean minimum temperature for several decades
• Days were also generally cooler than the July average, especially in the south, although the 25th and 29th brought temperatures in the mid to high teens to several locations
• Tasmania's mean maximum temperature for July was 0.11 °C below average
• Bushy Park and Maydena had their lowest July mean daily maximum temperature for several decades
• A few sites had their lowest July mean temperature on record, or the lowest in more than 20 years
• Tasmania's mean temperature for July was 0.34 °C below average, cooler than July last year but warmer than July 2015

Cold nights and some rain for Hobart

• Hobart's mean minimum temperature of 3.5 °C was 1.1 °C below the long-term average, the coolest month since June 2007 and the coolest July since 1982
• There were seven mornings when the temperature in Hobart dropped below 2 °C, above the long-term July average of about five mornings
• Hobart's mean maximum temperature of 12.2 °C was 0.5 °C above the long-term average, a degree cooler than July last year
• There were only three days where the temperature didn't reach 10 °C in Hobart, compared to the long-term July average of about seven such cold days
• A total of 37.2 mm of rain fell in Hobart, below the long-term average of 52.4 mm but still the wettest month since January and well above the June total of just 6.6 mm
