Tasmania in October 2016: cool, wet and windy

Tasmania had a cool, wet and windy October. Rainfall was very much above average in the west, temperatures were mostly below average, and several extreme wind gusts were recorded.

A wet month for most of Tasmania

  • Heavy rain at the end of September continued into the start of October as a low passed close to the State, with a few sites having their highest October daily rainfall on record on the 1st
  • More heavy rain later in the month, with some sites in the Midlands having their highest October daily rainfall on record to 9 am on the 22nd
  • Rainfall was well above average in western Tasmania, and a few sites had their highest total October rainfall on record; totals were below average in parts of the east
  • State average rain of 209 mm was 69% above average, the wettest October since 1988, and in marked contrast to the record dry October 2015
  • State average rain for the 10 months from January to October was the third-wettest on record, despite some generally dry months early in the year

Mostly cool days

  • Cooler than average daytime maximum temperatures for most of the month, and especially around the 12th and 22nd when snow fell on the highlands, but some mild days around the 15th, 25th and 30th
  • Mean maximum temperatures for the month between half and two degrees below average at most sites
  • State mean maximum temperature 0.72 °C below average, the coolest October since 2003 and in marked contrast to the very warm October 2015
  • Many cool nights but some mild nights: mean minimum temperatures for the month within half a degree of average at most sites and the State mean minimum temperature 0.14 °C above average

Strong and gusty winds

  • Tasmania experienced persistent and strong westerly winds on many days during the month, which intensified when low pressure systems passed close to the State
  • Maatsuyker Island registered a gust to 159 km/h on the afternoon of the 5th, Australia's strongest October gust recorded in the climate database. Kunanyi (Mount Wellington Pinnacle) recorded a gust to 156 km/h on the 9th, becoming the equal-second strongest October gust for Australia

Cool and wet in Hobart

  • Hobart's rain of 83.4 mm for the month was above the long-term average of 61 mm, and much wetter than the 14 mm received in October 2015
  • Daytime temperatures were 0.2 °C above the long-term average in Hobart, but 2.5 °C cooler than October 2015; the warmest temperature was 26.1 °C on the 15th
  • Overnight temperatures in Hobart were also 0.2 °C above the long-term average for October, with the coldest temperature 3.7 °C on the morning of the 13th
  • Several windy days in Hobart through the month, including a northerly gust to 106 km/h on the 9th and a southerly gust to 65 km/h on the 22nd

Notes

The Monthly climate summary 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. Later information, including data that has had greater opportunity for quality control, will be presented in the Monthly Weather Review.

A climate summary is generally published on the first working day of each month.

This statement has been prepared based on information available at 10 am on Tuesday 1 November 2016. Some checks have been made on the data, but it is possible that results will change as new information becomes available.

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.

The ACORN-SAT dataset is used for temperature area averages.
