Tasmania
in June 2008: Warm, and again dry in the east
It was another very dry month in eastern Tasmania, and even though there were some wet days in other parts of the state most areas had less than average June rain. Temperatures were above average overall (with some places having their warmest June on record), but there were some very cold and frosty nights and snowy weather. Westerly winds were dominant through the month, and there was a burst of exceptionally strong winds near the end of the month.

Details
Dry in the east: A series of cold fronts
crossing between
the 10th and the 13th brought rain to almost all areas, with some heavy
falls in the northeast: Ringarooma received 65.4 mm in the 24
hours to
9 am on the 13th. The next major rainfall event was around the 26th,
which brought 20 to 30 mm to the southeast, some of the heaviest
rain
seen there for several months; sites in western and central areas
received even more. Despite these falls, the relatively dry start to
the month meant Flinders Island, the East Coast, the Midlands, and
parts of the north were much drier than usual overall. The rest of the
state had rain within the "average" band, but even these were mostly
below their long-term June mean. Several sites on
the East Coast had less than 10 mm for the whole month, and some had
their lowest June
rainfall for
several decades.
Cradle Valley (Waldheim) recorded
both the
wettest single day of 82.6 mm on the 27th and the highest total of
286 mm (Mount Read, often the
wettest spot in the state, suffered malfunctions during the
month).
Mostly warm days - but some snow: There were a number of relatively warm days through the month, especially up to the 6th (when a high over the Tasman Sea directed mild air across the state), and around the 10th, the 18th and in the final two days (in northwesterly winds ahead of cold fronts). The most notable cold days were the 7th, 13th, 21st and 26th (all the result of cold fronts crossing from the west). Snow was seen settling below 500 metres on the 26th. The 17th was a very cold day in the Derwent Valley, when persistent fog kept the sun at bay. Overall, warm weather dominated cold, with mean maximum temperatures typically 1 to 1.5°C above average. Some sites had their highest June mean daily maximum temperature on record whilst Hobart, Burnie and Bicheno had their warmest since 1988.
Mostly warm nights - but some frosts: Mild nights were more common than cold ones during June, with some especially mild mornings around the 4th, the 10th to 12th, the 19th and at the end of the month. There were some cold mornings too, particularly the 6th to the 8th, the 14th to the 17th and around the 22nd and 24th; local frosts were reported on those days, with the east and southeast most affected. Mean daily minimum temperatures were above average across the state, typically by 1 to 1.5°C but by less than 1°C in the east and southeast. A few spots had their highest June mean daily minimum temperature or their highest for many years.
Windy weather: Westerly winds dominated the state for much of the month, and these were particularly strong from the 20th to the 27th. Some exposed sites recorded storm-force winds, and gales were reported from many areas. On the morning of the 26th, Hogan Island (in Bass Strait) recorded a gust to 180 km/h, the strongest gust recorded using standard instruments in Tasmania during June and the third-strongest gust ever recorded in the state (the strongest are both on Mount Wellington: 200 km/h in March 1998 and 193 km/h in August 2004). Even stronger winds were detected using alternative instruments at Cape Grim, and it is likely that still stronger gusts occurred in places without instrumentation.

Notes
This statement has been prepared based on information available at 10 am on 1 July 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.
