Tasmania in July 2022: fifth-driest July on record; warmer than average days, cooler than average nights

Rainfall was below average across almost the whole state, with large areas in the driest 10% of records for July. Reduced cloud cover contributed to warmer than average days for most parts, and cooler than average mornings for the northern interior.

Around half of Tasmania's normal July rainfall

  • Rainfall for July was 51% below average for the Tasmania as a whole.
  • It was Tasmania's fifth-driest July since 1900.
  • The most significant rainfall event for the month was on the 17th ahead of a cold outbreak that brought snowfalls down to around 200 m in the south, ranging to around 600 m in the north, on Sunday evening into Monday morning.
  • St Helens Aerodrome, with 22 years of record, had its highest July daily rainfall on record on the 24th under a north-easterly airstream.
  • Rainfall for the first seven months of 2022 has been in the driest 10% of January to July records for most of the western half of Tasmania.

Coolest July since 2017

  • Mean maximum temperatures were above average across the state, tending to near average for parts of the North East and East Coast districts.
  • Tasmania's mean maximum temperature was 0.43 °C above average, but still the lowest for July since 2017.
  • Mean minimum temperatures were below average for parts of the Central North, Midlands and Central Plateau districts, tending to near average elsewhere.
  • The mean minimum temperature was 0.60 °C below average, and was also the lowest for July since 2017.
  • A couple of sites with relatively short historical records had their coldest July day on record.
  • Several sites had their lowest July temperature on record on the 18th during a cold outbreak.
  • In contrast, Scotts Peak Dam had its highest July temperature on record and its equal highest July mean daily maximum temperature on record.

Hobart (Ellerslie Road)

  • Total rainfall for Hobart (Ellerslie Road) was 25.4 mm, which is 49% of the long-term average of 51.6 mm.
  • The mean daily maximum temperature for Hobart (Ellerslie Road) was 12.8 °C, which is 1.0 °C above the long-term average of 11.8 °C.
  • The warmest day was 16.8 °C on the 26th, and the coolest day was on the 18th when the temperature reached 7.3 °C.
  • The mean daily minimum temperature for Hobart (Ellerslie Road) was 4.7 °C, which is 0.1 °C above the long-term average of 4.6 °C.
  • The coldest morning was 1.1 °C on the 21st, and the warmest morning was on the 24th when the minimum temperature was 8.4 °C.

Notes

The Monthly climate summary, usually published in the first week of the following 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 6 pm on Tuesday 2 August 2022. 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.

Information about Australian Indigenous seasonal calendars is available at the Indigenous Weather Knowledge website.
