Monday, 3 March 2008 - Seasonal Climate Summary for Tasmania - Product code IDCKGC27R0
Tasmania in summer 2007−08: wet in some areas, dry in others, warm
overall
Some heavy rainfall events ensured that some parts of Tasmania had above-average rain for summer, notably the northeast. But a very dry January meant that the West Coast ended the season with below-average rain, as did the lower East Coast which missed out on some of the bigger falls of December. A very warm December and January ensured the summer as a whole had above-average temperatures, despite some cold weather during February.
Separate summaries are available for each of the months of summer: December 2007, January 2008 and February 2008, as is an archive of previous seasonal summaries for Tasmania, and many other climate summaries and diagnostics.

Details
Wet in some areas: There were a number of heavy rainfall events through summer, with thunderstorms prominent in December and troughs bringing heavy rain to the northeast in both January and February. The result was above-average rain in the northeast (although not on Flinders Island); Scamander had its wettest summer on record. Rain was also above average in other parts of the north, particularly because of some heavy rain events during December and February.
Dry in the some areas: January was a dry month across Tasmania; the driest on record in some areas. The lower East Coast missed out on most of the heavier rain events during December, and rainfall totals for the summer were below average there. In the western highlands, rain was at best average during December and well below average during January; the deficit was not made up during February so the area had below-average rain for summer.
Many warm days: December and January had many very warm days, with temperatures pushing into the 30s (Tarraleah had its hottest summer day on record). In both months mean daily maximum (daytime) temperatures were well above average. Although there were very warm days in February, most of the month (and especially the end) was rather cool. Taken over the whole summer, mean maximum temperatures were above normal, typically by 0.5 to 1.0°C, but in most places it was cooler than last summer.
Nights mild overall: Although there were a few cool nights right through summer, these were balanced by the many very mild nights, especially during December and January. Overall, mean daily minimum (overnight) temperatures were above average for summer, mostly by about 0.5°C, but cooler than last summer almost everywhere.

Notes
This statement has been prepared based on information available at 10 am on Monday 3 March 2008. 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.
