Tasmania in spring 2017: a warm season after a snowy start

A cold and snowy September gave way to a warm October and a record-breaking warm November, giving Tasmania its warmest spring on record in 2017. Rainfall was below average in the east and north, and well below average near the northern East Coast.

A record warm season, after a cold start

Rain well below average in the east

  • Total rainfall for spring was below average in the east and north, and well below average down the East Coast
  • It was particularly dry near the northern East Coast, where many sites had less than one-third of average spring rain and some had their lowest total spring rainfall since at least 1982
  • Totals were close to average in the west, partly due to a wet September
  • Taken across the State, rainfall was about 15% below the spring average

A record warm spring for Hobart

  • The mean daily maximum temperature for Hobart (Ellerslie Road) was a record high 19.2 °C, which is 2.3 °C above the long-term average of 16.9 °C. The warmest day was 31.9 °C on 18 October, and the coolest day was on 5 September when the temperature reached 9.3 °C
  • The mean daily minimum temperature for Hobart was a record high 9.3 °C, which is 1.5 °C above the long-term average. The coldest morning was 1.0 °C on 1 September, and the warmest morning was on 26 November when the minimum temperature was 17.3 °C
  • Combining maximum and minimum temperatures gave Hobart its warmest spring on record, with an overall mean temperature of 14.2 °C exceeding the record set in 2015 by 0.3 °C
  • Total rainfall for Hobart (Ellerslie Road) was 126.0 mm, which is three-quarters of the long-term average, and just over half the total received in spring last year

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 9 am on Friday 1 December 2017. 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.
