Tasmania in July 2019: very wet in the west, dry in the east, warm for July

Westerly winds and cold fronts brought plenty of rain to western Tasmania, but the east had a relatively dry July. Temperatures were above average, despite several cold days and nights.

Very wet in the west, but dry in the east

  • Westerly winds and cold fronts were dominant during July, bringing frequent rain to western Tasmania
  • Some fronts were particularly active or had embedded thunderstorms, giving a few sites their highest July daily rainfall on record
  • Rainfall totals were above average over the western half and the northeast highlands, and very much above average in the western highlands
  • Zeehan and Lake Margaret Dam had their wettest July since 1970, and a few other sites in the west with shorter records had their wettest July on record
  • The East Coast had below average rain, with some areas very much below average
  • Friendly Beaches, Swansea and Point Lesueur on Maria Island reported less than 20 mm for the whole month, about one-third their July average
  • Tasmania's total rainfall for the month was 36% above average, but not as wet as July 2018 (which was wet across Tasmania apart from the East Coast)
  • For the year so far, rainfall has been very much below average near the East Coast, but close to average over the western half of Tasmania

Mild for winter, but some cold days and nights

  • As is typical for winter, there were several cold days with snow or persistent fog, and cold nights with frost
  • Overall, temperatures were above average for the time of year, with several days well above average
  • With wind and cloud a frequent occurrence during the month, relatively mild nights were common, especially near the coast
  • Tasmania's mean minimum temperature was 1.39 °C above the July average, warmer than July 2018 but not as warm as July 2016
  • Tasmania's mean maximum temperature was 0.57 °C above average, a little warmer than last July
  • Tasmania's overall mean temperature for July was 0.98 °C above average
  • It has been a warm year so far, with some areas in the southeast having their warmest January to July mean maximum temperature on record

A mostly mild month for Hobart

  • Hobart had two days over 17 °C (the 1st and the 22nd) and seven days over 15 °C; the long-term July average is about three days over 15 °C
  • There were only two days that did not reach 10 °C (the 12th and the 13th), compared to a long-term average of about seven days that cold each July
  • The mean daily minimum temperature for Hobart (Ellerslie Road) was 6.0 °C, which is 1.4 °C above the long-term average of 4.6 °C
  • The coldest morning was 1.9 °C on the 27th; on average there are four or five mornings below 2 °C each July
  • The warmest morning was on the 1st when the minimum temperature was 10.0 °C

Notes

The Monthly climate summary, generally published on the first working day of each month, lists the main features of the weather in Tasmania using the most timely and accurate information available on the date of publication; it will generally not be updated. More extensive discussion of significant weather events, along with later information and data that has had greater opportunity for quality control, will be presented in the Monthly Weather Review.

This statement has been prepared based on information available at 9 am on Thursday 1 August 2019. Some checks have been made on the data, but it is possible that results will change as new information becomes available.

In some situations, some or all of the rainfall is in the form of hail or snow. In these cases the totals given are for the water equivalent: the depth of liquid water that results from melting any frozen precipitation. There can be significant 'undercatch' of snow in strong winds, meaning the true precipitation can be higher than that reported.

Averages for individual sites are long-term means based on observations from all available years of record, which vary widely from site to site. They are not shown for sites with less than 10 years of record, as they cannot then be calculated reliably.
The median is sometimes more representative than the mean of long-term average rain.

The Rank indicates how rainfall this time compares with the climate record for the site, based on the decile ranking (very low rainfall is in decile 1, low in decile 2 or 3, average in decile 4 to 7, high in decile 8 or 9 and very high is in decile 10).
The Fraction of average shows how much rain has fallen this time as a percentage of the long-term mean.

Where temperature area averages are mentioned, they are derived from the ACORN-SAT dataset.
