  • The Bass Strait Islands were generally wetter than average, so too was an area of the central west coast, while parts of the far south tended to below average.
  • Several sites had their highest winter daily rainfall on record.
  • June was relatively dry in the west and wet in the east, conversely, July was wet in the west and dry in the east, while August was wet in the central west and dry for parts of the east coast but close to average for most of the state.
  • There was moderate flooding along the South Esk and Macquarie rivers during June, and minor riverine flooding for large parts of central and eastern Tasmania in August.

Notes

The Seasonal 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 12 pm on Wednesday 1 September 2021. 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.
