Tasmania in January 2008: a warm, dry start to the year

The first month of 2008 was the driest January on record for many parts of Tasmania, particularly in the west and south. Only northern parts of the East Coast received near average rainfall for the month. January was also very warm, especially during the first two weeks. Some cooler weather was felt during the second part of the month, but there were very few really cold days.

Details

Very dry, except in the northeast: There was very little rain throughout January, with many southeastern and northwestern locations registering less than 10 mm for the month. Numerous sites recorded their lowest total January rainfall on record, or their lowest for several decades, with Marrawah, Cape Grim and Bull Bay experiencing their driest month for any part of the year. Only the northeast of the state had rainfall totals even close to normal, due predominately to a rain event around the 20th during which several northern East Coast locations recorded falls of over 40 mm in the 24 hours to 9am. A few other rain events, notably around the 13th and 27th to 31st, were not enough to prevent the record dry in many parts of the state. 

A warm start to the year: The first half of January saw many warm to hot days with temperatures well into the 30s, culminating on the 10th when Ouse reached 37.7°C. Devonport Airport reached 30.1°C on the 11th, the warmest there in 17 years of record. Some cooler weather between the 13th and the 22nd brought the monthly means down, with temperatures rising slightly above average during the last week of January until a cold change on the 31st. A few sites had their highest January mean daily maximum temperature on record, and some more had their highest for many years. Mean maximum temperatures were above average across the state, typically by around 2 to 3 degrees inland and 1 to 2 degrees at coastal locations.

Some very warm nights: It was very mild going into the morning of the 1st, and there were several other very warm mornings through the month, notably the 5th, 6th, 11th, 19th, 20th and 27th. There was a period of cooler nights around the 21st, but overall mean minimum temperatures were above average across most the state, typically by about a degree. A few eastern locations had their highest January mean daily minimum temperature on record, or their highest for many years. Mean minimums were close to average in western areas.

Notes

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

Normals 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 "normal" 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, normal in decile 4 to 7, high in decile 8 or 9 and very high is in decile 10).
The Fraction of normal shows how much rain has fallen this time as a percentage of the long-term mean.
