Tasmania in June 2020: very wet days in the southeast

Rainfall for June was above to very much above average in the southeast thanks mainly to heavy rain on the 23rd. Both daytime and night-time temperatures were close to average or warmer than average for the month as a whole, but there were several cold nights, particularly in the east during the first half of the month.

Wet in the southeast

  • Rainfall in June was above to very much above average in the southeast, but below average across parts of Tasmania's north and west
  • Rainfall for Tasmania as a whole was very close to average and after several drier than average years, it was the wettest June since 2016
  • On the 23rd, heavy rainfall in the southeast saw some areas record more than their June average rainfall in 24 hours and several sites had their highest June daily rainfall on record
  • The heavy rain on the 23rd was generally the most significant for the Hobart area since the destructive event of 10–11 May 2018
  • The 3-day rainfall totals from 22–24 June were more than double the June monthly average for parts of the State's southeast, with kunanyi (Mount Wellington Pinnacle) exceeding its June multi-day rainfall records for periods of 2 to 7 days
  • Lucaston (Bakers Creek Road) had its highest total June rainfall on record
  • Year-to-date rainfall totals have generally been above average, particularly in the east

Some cold nights

  • Daytime temperatures were generally above average in the west but close to average in the east
  • The mean maximum temperature for Tasmania was 0.12 °C above average, the lowest in June since 2015
  • Despite several cold mornings during the month, night-time temperatures were generally warmer than average across Tasmania
  • In Hobart, there were three mornings below 2 °C, compared to a June average of four such cold mornings
  • The mean minimum temperature for Tasmania was 0.45 °C above average, the highest since the very much wamer than average June 2016
  • Friendly Beaches and Ross (The Boulevards), each with less than 30 years of observations, had their lowest June temperatures on record
  • Year-to-date mean maximum temperatures have generally been close to average throughout the State and mean minimum temperatures have been warmer than average so far this year

Hobart (Ellerslie Road)

  • Total rainfall for Hobart (Ellerslie Road) was 84.2 mm, which is 157% of the long-term average of 53.7 mm

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 10 am on Wednesday 1 July 2020. 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.
