Wednesday, 1 April 2009 - Monthly Climate Summary for Queensland - Product code IDCKGC24R0
Area averaged across the state, Queensland received 27.87 mm compared to the long term March average of 93.73 mm, and based on figures since 1900. This ranks March 2009 as the 6th lowest since 1900, and is the lowest March rainfall since 1991 (area average for March 1991 was 17.82 mm).Rainfall was remarkably different to that of February, and much of the state was below to very much below average, despite the presence of two Tropical Cyclones located off the east coast during March.
On the 4th, a tropical low formed in the Coral Sea east of Lockhart River, which drifted to the southwest and intensified into a tropical cyclone. The tropical cyclone was named "Hamish" at about 10pm on the 5th of March and tracked almost parallel to the coast from the 5th to the 9th of March, but never crossed land. It reached category 5 on the 7th of March and produced damaging winds, large waves and elevated sea levels. There were some high daily rainfall totals during its track, mainly at coastal locations. The highest daily total was recorded at Mackay with 196.2 mm to 9am on the 8th, where around 150 mm fell between 9am and 3pm on the 7th.
Early on the 24th of March, Tropical Cyclone "Jasper" was located around 1010km northeast of Mackay, and was travelling in an east southeast direction, and posed no immediate threat to Queensland. Tropical Cyclone "Jasper" weakened to a low pressure system by the 26th and was located near New Caledonia.
March, the wettest overall was 637 mm at Bellenden Ker Top Station, then 447 mm at Nerada Alert, then
442 mm at Central Mill Alert, followed by 438.8 mm at
highest daily totals were 196.2 mm at Mackay on the 8th,
then 181.8 mm at Innisfail on the 12th, followed by
166.0 mm at Nerada Alert
on the 7th.
These stations are located in the north tropical and central coast districts and the highest daily totals occurred as Tropical Cyclone "Hamish" tracked south east, with the exception of Innisfail, which was caused by slow moving showers that yielded locally heavy falls.

higher than average over the south west, while the remainder of the
state fell within a degree of the long term average.
Mean minimum temperatures were above average over the southwest, but much cooler than average over the central districts and in the northwest.

Some sites had their warmest March night (highest daily minimum temperature) on record.However, area averaged across the state the minimum temperature was 20.19°C compared to a long term average of 20.65°C (−0.46°C below). Some sites had their lowest March temperature on record. While some sites had their lowest March mean daily minimum temperature for at least 20 years.

This statement has been prepared based on information available at 9 am on Wednesday 1 April 2009. Some checks have been made on the data, but it is possible that results will change as new information becomes available.
Averages 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. *In this case, averages from a
nearby suitable site have been used instead
(these are marked with an *).
The median is sometimes more representative than the mean of long-term average rain.
The Rank indicates how rainfall this time compares with the climate record for the site,
based on the
(very low rainfall is in decile 1, low in decile 2 or 3,
average in decile 4 to 7, high in decile 8 or 9
and very high is in decile 10).
The Fraction of average shows how much rain has fallen this time as a percentage of the long-term mean.
