Tasmania in 2013: a hot start, then wet and windy

Record high temperatures at the start of January were followed by plenty more warm weather, ensuring Tasmania recorded its 4th-highest mean temperature in 2013. Despite the overall warmth, there were some very low temperatures reported. It was frequently wet and windy from July to November, with repeated heavy rain and flooding.

  • Record hot to start the year
  • Tasmanian mean temperature 4th-warmest on record, 0.63 °C above normal
  • Some low temperatures
  • A dry start, then wet from July to November with repeated heavy rain and flooding
  • A windy spring
  • A warm year for Hobart

The Bureau of Meteorology's Australian annual climate statement is also available.

A very hot start to the year

On 4 January, Hobart reached 41.8 °C, the second-highest temperature ever recorded in Tasmania and a full degree higher than Hobart’s previous record. After a dry end to 2012, high temperatures and strong winds on that day saw numerous fires run out of control. The most destructive of these was a fire that started near Forcett then rapidly expanded. Significant infrastructure including the school and police station in Dunalley, 193 dwellings, and 186 other buildings were destroyed or seriously damaged. There were also losses of stock, vehicles and farm machinery. The fire continued to burn for most of the month, eventually reaching over 25 000 ha.

Hobart was just one of the sites that had its hottest recorded day on 4 January. The heat was not confined to Tasmania, as detailed in Special Climate Statement 43 – extreme heat in January 2013.

Warm weather dominated much of the year in Tasmania. A prolonged heatwave affected Tasmania and the rest of southeast Australia between 2 and 13 March, helping create the warmest March ever recorded in Tasmania. The March heatwave was characterised by prolonged sequences of days and nights above threshold temperatures, and was accompanied by high humidity and generally light winds. Launceston reached 30 °C on 8 consecutive days from the 5th to the 12th, double the previous record for such a warm spell. The heatwave affected Victoria and SA as well, as detailed in Special Climate Statement 45 – a prolonged autumn heatwave for southeast Australia.

Warm weather continued well into autumn: temperatures in the mid-twenties on 27 April combined with strong and gusty winds and saw several fires flare in the southeast. Even in winter mild weather was to the fore, with unseasonably warm days and nights in July.

Some low temperatures

There was cold weather, despite the overall warmth. For example June started off very mild but saw a stretch of cold days and nights from the 14th to the 25th. Liawenee had a run of 5 nights below −9 °C from June 21 to 25, touching −11.2 °C on the 23rd, and on the 21st persistent fog kept temperatures below 4 °C all day in the Upper Derwent Valley. On 9 July Liawenee fell to −12.2 °C, Tasmania’s second-lowest July temperature (just shy of the −12.5 °C at Butlers Gorge on 1 July 1983, and not far off the all-time record of −13.0 °C at Tarraleah, Butlers Gorge and Shannon on 30 June 1983). Even later in the year there was cold weather: on the morning of 13 September there was snow to low levels, Liawenee dropped to −8.8 °C and a few sites registered their lowest September temperature on record.

November days were much cooler than normal, especially in the southeast where average temperatures were almost the same as they had been in September. On November 8 a cold burst saw several sites in the north struggling to reach double digits, and Launceston Airport’s 9.7 °C was the first time a November day had not reached 10 °C there.

Warm overall

Looking at the year as a whole, Tasmania’s mean temperature was 0.63 °C above the 1961–90 average of 10.35 °C, making it the 4th-warmest year (1988 holds the record at 0.86 °C above normal). The mean daily maximum temperature for 2013 was 6th-warmest at 0.68 °C above the normal of 14.71 °C, (the record was in 1988 which was 1.04 °C above normal). The state’s mean minimum temperature was 5th-warmest at 0.58 °C above the normal of 5.99 °C (the 1988 record was 0.67 °C above normal). Several sites set records for highest mean daily maximum temperature, highest mean daily minimum temperature, or highest mean temperature.

A dry start, then wet from July to November

The hot weather early in the year brought very little rain with it, and for the first half of the year more areas had below-average rain than above-average. This all changed in July, which saw several heavy rainfall events in different parts of the state. August was exceptionally wet across most of Tasmania, September saw above-average rain in many areas, persistent westerly winds made October a wet month for the west and November saw heavy rain in the east.

It was very wet in the west through the cool part of the year, and this ensured that the state as a whole averaged 1543.1 mm for the year, about 11% above the 1961-90 average. Mount Read received at least 4242 mm for the year (the gauge was affected by snow on several occasions and the true total is not known); Lake Margaret Power Station's 3093 mm was the highest confirmed total. The 879 mm at Launceston (Ti Tree Bend) was the wettest year at that site since records began in 1982, although higher annual totals have been recorded at other sites in Launceston in the past, including 955 mm at Launceston (7EX) in 1971 and 1056 mm at Launceston (City) in 1946.

Repeated heavy rain and flooding

Heavy rain and flooding affected various parts of Tasmania throughout the year, especially when low pressure systems or cold fronts crossed the state between July and November. A cold front that crossed on 4 July saw totals over 50 mm in the north, then a low and trough generated heavy rain across the northwest on the 14th. Another system brought heavy falls to elevated areas on 18 July, and a low caused persistent heavy rain in the southeast on the 21st and 22nd.

The pattern continued into August, with notable heavy falls on the 5th, 13th and 18th that brought flash and riverine flooding, especially to the north. More wet days followed in September, especially from the 9th to the 11th and again from the 17th to the 19th. Gray (Haven of Hope) recorded 119 mm in the 24 hours to 9 am on the 18th, and the South Esk and North Esk rivers flooded once more. October was yet another wet month, especially in the west, then in November there was local heavy rain and flooding three times as low pressure systems passed close to the state: Gray recorded 258 mm in the 24 hours to 9 am on 13 November.

Even during the relatively dry first half of the year there were some heavy rain events. Daily totals over 60 mm were reported at several sites in the 24 hours to 9 am on 22 March, and isolated heavy showers on 8–9 April saw over 156 mm at Eaglehawk Neck.

The repeated rain brought floods to many rivers. In the middle of August there were three river catchments in moderate flooding (North Esk, South Esk, and Mersey) and another three in minor flooding (Meander, Macquarie and Forth). From July to November, the North Esk River at Corra Linn went into minor flood ten times, reaching moderate flooding twice in one week in August. The South Esk River at Fingal reached moderate flood level seven times, and the Macquarie River at Cressy reached minor flood level five times and moderate twice.

An exceptionally windy spring

Westerly winds are a common feature of Tasmania’s weather, especially during spring. This year gusty westerlies were even more prevalent than usual, and damaging winds were reported in different parts of the state through the year especially during October when wet weather made conditions especially difficult. Gusts of 161 km/h were reported at Maatsuyker Island on 5 July, Cape Grim on 19 August, and Hogan Island on 26 September.

A warm year for Hobart

Hobart had its hottest day on record on 4 January, with 41.8 °C breaking the previous record of 40.8 °C set on 4 January 1976. This is the highest temperature recorded in southern Tasmania, and the second-highest anywhere in the state. The previous record of 40.8 °C stood as Tasmania's highest temperature on record for 33 years, before it was broken by Scamander's 42.2 °C on 30 January 2009.

Like much of Tasmania, warm weather dominated during 2013, especially in the first half of the year. There were some low temperatures, including −0.4 °C on the morning of 21 August (Hobart’s coldest morning in 41 years).

Hobart’s mean temperature for the year was 13.8 °C, a record high and 1.2 °C above the long-term average. 2012, 2010 and 1988 all share the previous record high of 13.7 °C. The mean daily maximum temperature was 18.1 °C, which is 1.2 °C above the long-term average, just shy of the 18.2 °C record from 2010 and equalling the value from 2012. Hobart's mean daily minimum was 9.4 °C, which is 1.5 °C above the long-term average, equal second-warmest with 2000 but behind the 9.5 °C record from 1988. Observations started at the current site in Hobart in 1882, and since mid-1895 have been made in a standard Stevenson screen.

Hobart recorded 610 mm for the year, just below the long-term average of 616 mm. There were a few wet days, notably 43 mm in the 24 hours to 9 am on 22 July, and daily totals over 20 mm on 22 March, 15 June, 6 July and 1 October. At the other extreme, Hobart had only 11.4 mm for all of January.

During 2013, Hobart had 33 days with gusts of 80 km/h or more, 10 of which were during October; the long term average is just 22 such windy days with only 3 in October. Hobart’s strongest wind gust for the year was 102 km/h, recorded on both 3 May and 5 October.

Notes

A Annual Climate Summary is prepared to list 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, usually published in the fourth week of the month.

This statement has been prepared based on information available at 9 am on Friday 3 January 2014. Some checks have been made on the data, but it is possible that results will change as new information becomes available.

Averages 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 being used for temperature area averages from December 2012 onwards. The major change from earlier datasets is that the ACORN-SAT dataset commences in 1910, rather than 1950, and hence rankings are calculated using a larger set of years.
