Tasmania in spring 2007: dry in the east
Summary
Rainfall was below average in most areas of Tasmania during spring 2007, and very much below average in the east; only a very wet October kept the west close to average. Temperatures were above normal across the state.
Summaries are also available for the individual months of September, October and November 2007, as is an archive of the summaries for previous seasons. It is intended that the summaries for December and all of 2007 will be published on Wednesday 3 January 2008.

Details
Dry in the eastern half: A fairly wet September and a very wet October in the western half were balanced by a dry November, but the eastern half missed out on much of the rain throughout the three months. A few sites had their lowest total spring rainfall on record and several more had their lowest total spring rainfall since at least 1982. The wettest spot for spring was Mount Read, with 928 mm (even though one day of rain in September was not reported); 515 of this fell during October including over 200 mm in just two days, whilst it could manage only 40 mm for all of November. At the other extreme, some sites in the east had less than 50 mm for the whole of spring.
Warm days predominate: A number of sites had either their highest spring mean daily maximum temperature on record; others (including Hobart and Burnie) had their warmest since 1987. Across the season, daytime temperatures were about a degree above average in most areas, and over a degree in the Midlands and near the Derwent Valley. There were some abnormally cool days during September, but there were lots of warm days as the season progressed: temperatures reached into the low 30s on several days in November.
Some cold nights, but mild on average: Cold nights were quite common during September and October, but much less frequent in November. Averaged over the whole season, minimum (overnight) temperatures were a little above average in most areas (with Bicheno managing a record), but just a little below average at some locations.
Some fronts, but some highs: There were persistent westerly winds through the last week of September and right through October, with many gusts in excess of 100 km/h. However, the first three weeks of September and most of November saw Tasmania's weather dominated by high pressure systems.

Notes
This statement has been prepared based on information available at 10 am on Monday 3 December 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
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.
