Tasmania in October 2006

A month of extremes

Jump to: Extremes Records Summaries Notes the top

Summary

October was a month punctuated with extreme events - a record hot day on the 12th with severe bushfires in the south and record cold days on the 16th, 21st, 28th and 29th with severe frosts reported in the north and snow to low levels reported across the state. Gale force winds were experienced in many areas on the 11th, 12th, 18th and 19th but only minor damage was reported. Despite the late rain, it was still very dry over most of the state. In general, it was warmer than average during the day and cooler than average overnight.

Rainfall

Although it may have appeared wet - especially toward the end of the month - rainfall was again quite sparse across the state. The most significant falls were reported on the 5th, 6th and 27th of the month with lesser falls on the 14th, 17th and 24th. Overall, only the southern and western parts received close to average rainfall with a small area  in the Derwent Valley with above average rain. The rest of the state was very dry, especially the north coast where some stations had less than 10 mm for the whole month. Many stations in the north had their lowest total October rainfall on record, including  Burnie, Devonport, Scottsdale and Launceston; many other sites reported their lowest October rainfall for at least 20 years. Burnie, for example, had only 12.8 mm for the month, the driest October in its 62 years of record and just a fraction of its long-term average of 88.2 mm. Devonport had less than 5 mm for the month, a tiny fraction of its October normal 66.9 mm.
With most of the past 10 months being relatively dry, a number of sites in the north and the southeast have had their driest-ever January-to-October, or their driest for many years. At some, total rainfall is less than half that expected over the 10 months; Burnie for example has had only 367 mm so far this year compared to a January-to-October average of 831 mm and an annual average of 968 mm.

Maximum temperatures

The most significant event for October was the extremely hot day experienced on Thursday the 12th, with several major bushfires raging out of control in many parts of the state. After an already warm day on the 11th, temperatures soared into the thirties on the 12th, with Hobart Airport, Flinders Island and Bicheno (among others) recording their hottest October day ever. Hobart, Hobart Airport, Campania and Bull Bay had temperatures over 33°C and Campania topped the state with 34.3°C, the second-highest October temperature ever registered in Tasmania. Over twenty major fires burned across the state on that day, the most severe was on the eastern shore of Hobart where many hundreds of hectares were burned out and lives and property were put at risk.
Just two weeks later on the 27th and 28th, a deep polar airstream affected the state bringing widespread sleet, hail and snow to many areas. Although generally settling to 200 metres, snow was reported on the beach at several locations including Lauderdale and Clifton in the southeast. During this time, daytime temperatures were up to eight degrees below average in the south, but about two degrees below average in the north.
Maximum temperatures for the month were mostly above average, especially over the east coast and the southeast, but just a little below normal in the northeast. Eddystone Point had its highest mean daily maximum temperature for October, whilst Swansea and Hobart Airport had their highest October mean daily maximum for at least 20 years.

Minimum temperatures

Overnight minima followed the pattern of extremes seen in daytime temperatures. It was exceptionally warm on the night of the 11th and 12th with many sites in the south and east reporting their warmest October night on record on the 12th. These included Bruny island, Swansea, Hobart Airport and Bicheno - the warmest was at Strahan Aerodrome with 19.2°C.
In contrast, there were several very cold nights, notably the 16th, 21st, 22nd, 26th, 28th and 29th, mainly due to cold air associated with the passage of cold fronts or the position of high pressure systems over the state. Some places (including Launceston) reported record low October temperatures, and Scottsdale reported its record lowest October average minimum. Severe frosts were reported statewide on these cold mornings, especially on the 16th and 28th, and major frost damage was reported in apple, pear and stonefruit crops as well as some vineyards.
On average, minimum temperatures were cooler than average statewide (apart from a small pocket in the southeast) - particularly in the northeast where temperatures were about 1.5°C below average.

Notes

This statement has been prepared based on information available at 10 am on Wednesday 1 November 2006. Some checks have been made on the data, but it is possible that results will change as new information becomes available.

Normals are 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 Rank indicates about where rainfall this time ranks in the climate record for the site.
