Temperatures

The national mean temperature for november was above average for Australia as a whole, at 1.05 °C warmer than average.


Both mean maximum and mean minimum temperatures were above average for november at 0.92 °C and 1.18 °C above average, respectively.



For Victoria, the mean minimum temperature for the month was the third highest on record for O. No other state nor the Northern Territory placed amongst the ten warmest on record for either mean maximum or mean minimum november temperatures.


Maximum temperatures for november were above or very much above average across much of Western Australia, the far northern tropics, and most of the eastern halves of both Queensland and New South Wales, extending into parts of bordering Victoria.


The mean minimum temperature for the month was above or very much above average for most of Australia, although much of Central Australia, parts of north-west Western Australia, the south-western half of Tasmania, and some pockets of east coast Queensland were close to average. A few sites in New South Wales had their highest november mean daily minimum temperature on record for november.


A small pocket on the coast of the western Kimberley in Western Australia observed a cooler than average mean minimum temperature for the month. Some stations in the north had record low november daily maximum temperatures, while others scattered across the state had their coolest november night on record.


A large number of stations in South Australia and a few in the Northern Territory observed record low november daily maximum temperatures during the first week of the month, but some also recorded their highest november daily minimum temperature on record on the 3rd.

Rainfall

november rainfall was 35% above average for Australia as a whole.


Rainfall for the month was above average across much of the country, and very much above average (decile 10) for november in large parts of South Australia, and areas of the Northern Territory, south-west New South Wales, eastern Victoria and New South Wales, and the east coast of Tasmania.


Rainfall was below to very much below average for the south-west of Western Australia. A large number of stations had their lowest november total rainfall on record, or lowest for at least 20 years. Rainfall for the month was also below average for an area of the Warrego and Maranoa in Queensland.


A cold front extending from the Tasman Sea south-east of Tasmania to the eastern interior of Western Australia brought a wet start to the month for much of south-eastern Australia. The southern end of the front stalled near Tasmania on the 4th and the 5th as the northern part tracked across the southern mainland during that and the following day. An inland low pressure system developed over Victoria on the following day, also bringing moderate to heavy rainfall in parts of the state, while tropical moisture flowed south along an inland trough extending from the low in Victoria to another in the Top End of the Northern Territory with associated rainfall along the path of the trough.



Between the 4th and the 9th a large number of stations in Tasmania, Victoria, the Northern Territory, and South Australia observed daily rainfall records for november, with some stations in each state observing their wettest november overall.


The month also had a wet end in the southeast of Australia as cold fronts and troughs combined with moist, warm air and brought stormy weather, including some severe thunderstorms and heavy rain. A large number of stations on the central and mid-north coast of New South Wales had their wettest november day on record during the last week of the month, while a large number of stations in the state also had either their highest november total rainfall on record, or highest for at least 20 years
