Thursday, 1 December 2011 - Monthly Climate Summary for Tasmania - Product code IDCKGC17R0
Tasmania in November 2011: Wet in the north and westNovember rainfall totals were above average in the north and west of the state due to west to northwest winds, and a low pressure system at the end of the month that brought local record falls. Maximum temperatures were warmer than average, by up to two degrees in the south and east. Nights were also a degree or so warmer than average.
- A record 111 mm at Eddystone Point on the 27th
- Wettest November on record for Launceston and Strahan
- Hobart’s warmest November in 29 years
- Warm days and nights
- Above average rainfall in the north and west
A spring summary has also been prepared.
Wet in the north and west
West to northwest winds ensured
that rainfall totals were close to average in the north and west of the
state throughout the month. A low pressure system moving to the
northeast on the 26th extended rain state wide, with heavy falls in the
northeast. Eddystone Point’s 111m in the 24 hours to 9 am on
27th was its wettest
November day on record. Launceston (Ti Tree Bend) had 117 mm
for the month, its wettest
November on record; Strahan’s 189 mm was
also its wettest
November. Some sites had their highest
total November rainfall for at least 20 years.
The east was relatively dry for most of the month, but the low on the 26th and a string of cold fronts in the final week brought totals close to average. Mount Read was the wettest location overall with 421 mm.
Warm days in the east
November days were warmer than average in eastern Tasmania, whilst the
rest of the state had cool and mild days mixed throughout the month.
Overall, maximum temperatures were up to one degree warmer than normal
in the northwest and up to two degrees warmer than normal elsewhere.
The warmest periods were around the 6th, 9th and 24th when
northwesterly winds ahead of cold fronts pushed temperatures into the
upper 20s at most locations, peaking at 31 °C in Swansea on the
6th. The coldest days were at the start of the month in a cool
southwest flow, and around the 20th to 23rd, when daytime temperatures
generally remained in the low to mid teens. Mount Read recorded the
lowest maximum temperature on the 2nd with 3.4 °C.
Mild November nights
minimum temperatures were up to one degree warmer than normal in most
areas for November. There were several mild nights, the warmest of
which were from the 6th to the 14th, the 19th, and the 26th to the
30th. On the 19th and 30th, minimum temperatures were 5 to 8 degrees
warmer than average across Tasmania due to cloudy conditions and mild
northerly winds ahead of cold fronts. Flinders Island had the warmest
night, the temperature not falling below 17.5 °C on the 19th.
The coldest nights were from the 2nd to the 5th and the 15th to the 17th. On the morning of the 15th, temperatures were two to five degrees below average as a result of clear overnight skies. The temperature dropped to -3.4 °C at Liawenee, the coldest morning of the month.
Hobart’s warmest November in 29 yearsDay time temperatures were close to 2 °C warmer than average in Hobart, due to most days being mild; almost every day from the 4th onwards was warmer than average. This resulted in Hobart experiencing its warmest November days since 1982. The warmest day was the 6th, when the temperature reached 30.7 °C.
There were also several mild nights in Hobart, resulting in a monthly minimum temperature close to one degree warmer than normal.
November rainfall was below average for most of the month; there were several days of rain, but daily totals were usually only a few millimetres or so. A low pressure system moving to the east of Tasmania delivered 23 mm in the 48 hours to 9am on the 28th, almost half the overall monthly total of 55 mm (which is just above the long-term average of 54 mm).

A Monthly 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 Thursday 1 December 2011. 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
(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.
