Monday, 2 April 2007 - Monthly Climate Summary for Tasmania - Product code IDCKGC17R0
Rainfall was about average across much of Tasmania during March, although there were some patches drier than average and some wetter, mostly the result of cold fronts toward the end of the month. Temperatures were generally above average, although not by nearly as much as in February.
Average rainfall across most of the state: In contrast to the persistent pattern of easterlies seen in February, March saw more autumn-like conditions with westerlies and cold fronts bringing rain and showers, especially to western districts. Consequently, rainfall was about average across most of the state. It was drier than average in parts of the southeast, including the lower Derwent Valley and the southern Midlands. Cold fronts, particularly systems that crossed on the 23rd and the 29th, brought above-average falls to the western highlands. A low near the state at the start of March brought rain to the eastern half, ensuring that the central east coast had above-average rain for the month.
A few hot days: Although there were more cool days than warm ones during the month, there were a few especially hot days, particularly on the 3rd, 15th, 22nd and 23rd. Wynyard had its highest March temperature on record on the 23rd, the same day that Flinders Island Airport reached 33.4°C. Over the month, daytime temperatures were above average across the state, typically by about half to one degree. The far northwest, the central north and the northern east coast were a little warmer still: Wynyard and Eddystone Point had their highest March mean daily maximum temperature on record.
Several cool nights: Cold nights were more common than warm ones during the month, but some especially warm mornings (the first three mornings, on the 16th, and again on the 23rd) ensured minimum temperatures for the month were slightly above average overall, although generally by less than half a degree. Especially cold nights occurred on the 6th, the 18th (when Liawenee dropped to −2.8°C), the 25th and the 26th.

This statement has been prepared based on information available at 10 am on Monday 2 April 2007. 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
from all available years of record, which vary widely from site to
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.
