Tasmania in March 2017: a very warm month

March in Tasmania brought many warm days, and in stark contrast to the cool February; it was the third-warmest March for the State as a whole. Rainfall was below average for most areas, and well below average in the west.

A very warm month

Rain below average in the west, with few westerly winds

  • Rainfall totals were well below average in the west of the State, with a few sites having their driest March since 1994
  • Totals were close to average in the northern Midlands and on the Bass Strait islands, after a few days with localised moderate falls
  • Although slow-moving high pressure systems controlled Tasmania's weather for much of the month, the passage of cold fronts or troughs did bring rain on some days
  • Westerly winds were less common than they had been during January or February
  • Strong and gusty winds occurred with the passage of cold fronts, with the strongest on the afternoon of the 27th when damaging gusts over 100 km/h were reported in several areas

A warm month for Hobart

  • Along with the rest of the State, Hobart had a very warm March; Hobart's mean maximum temperature of 22.4°C was 2.3 °C above the long-term average
  • Hobart reached 32.1 °C on the 14th and 31.7 °C on the 15th, the first time the city has had two consecutive March days that warm
  • Nights were especially mild in Hobart, with a mean minimum temperature of 12.9 °C that was not only 2.0 °C above average but also 1.1 °C warmer than February
  • Hobart registered 37.0 mm of rain in March, a little below the long-term average of 44.7 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 8 am on Monday 3 April 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.

From 2017, information about Macquarie Island can be found in the climate summary for the Remote Islands and Antarctica

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.
