Tasmania in June 2019: Cold nights, a wet end in the northwest

Cold nights were common in Tasmania during June, but despite a run of cold weather from the 19th days were warmer than average overall. Rainfall was below average in most areas for most of the month, until a low approaching from the west brought rain to the northwest near the end of the month.

Wet in the north, dry in the south and east

  • Much of the State had below-average rain for most of the month, but moderate to locally heavy falls in the northwest in the final few days ensured a wetter than usual June there
  • Rainfall was below average in the south, and especially near the Derwent Valley: Bushy Park reported just 9.8 mm, its driest June since 1930
  • Total rainfall for Tasmania was about 9% below average
  • Over the first half of the year, rainfall has been below average for much of Tasmania and very much below average in the east and southeast

Cold nights, but days warmer than average

  • Cold nights were common during June, with a particularly long spell from the 20th to the 27th (Launceston had five consecutive nights below -1 °C), although there were some relatively mild nights around the 11th
  • The morning of the 24th was especially cold, bringing Ross and King Island Airport their lowest June temperature on record
  • Most days were warmer than average, but there was a run of cold days from the 19th to the 24th
  • There was a burst of warm weather on the 28th and 29th, with several sites reporting maxima into the high teens; Scotts Peak Dam in the southwest had its warmest June day in its 21 years of record
  • Averaged over the month, maximum temperatures were above average, and the State's mean maximum temperature was 0.49 °C above average
  • Minimum temperatures very much below average in the northeast, but above average near the west and south coasts; the State's mean minimum temperature was 0.21 below average
  • Tasmania's overall mean temperature was 0.14 °C above average, a little cooler than June 2018
  • The first half of the year has been warmer than average across Tasmania, with the mean maximum temperature for January to June among the warmest on record in the southeast

Dry with cold nights for Hobart

  • Total rainfall for Hobart (Ellerslie Road) was 19.4 mm, which is 36% of the long-term average, drier than June 2018 but wetter than June 2017
  • The mean daily maximum temperature for Hobart (Ellerslie Road) was 13.6 °C, which is 1.6 °C above the long-term average of 12.0 °C
  • The warmest day was 18.1 °C on the 28th, and the coolest day was on the 25th when the temperature reached 9.9 °C
  • The mean daily minimum temperature for Hobart (Ellerslie Road) was 5.5 °C, which is 0.3 °C above the long-term average of 5.2 °C
  • The coldest morning was -0.2 °C on the 25th, only the third time in the last 20 years that Hobart's temperature has dropped below zero

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 Monday 1 July 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.
