An archive of previous monthly summaries for Queensland is also available, as are summaries for other states and many other climate summaries and diagnostics.

Details

Rainfall was well above average in the far northwest, the central interior, parts of the Herbert and Lower Burdekin, and the southeast districts.Generally close to the April average over the remainder of the state. Much of the rain fell in the first half of the month, with significant figures and details below.

Maximum temperatures were generally close to, or slightly above average across the state. Minimum temperatures were slightly below average in the north, but slightly above average over the southern parts. However, the last few days of the month saw large areas across the southern districts and central interior recording up to 10°C below the long term April average.

Rainfall

At the beginning of the month, a surface trough was located off the southern coast of Queensland, with a low embedded in this trough. Aided by an upper level low pressure system the combination produced areas of moderate to heavy falls over the southeast coast. After midday on the 2nd,  flood warnings were issued for the Sunshine Coast streams as very intense rainfall of 150 to 300 mm was recorded over the previous 3 hours in the northern areas of the Sunshine Coast (including the catchments of the Noosa and Maroochy Rivers, and Six Mile Creek). Flood warnings were also issued for the Mary River and tributaries as similar falls of 150 to 300 mm were recorded in the same time period in the Cooroy and Pomona area to the west of Noosa. Between 9am and 3pm on the 2nd, 413 mm fell inland of Noosa, while places around the Sunshine Coast recorded 130 mm. Black Pinch Road Alert recorded 464 mm to 9am on the 3rd.

By the 3rd, the trough lay off the Wide Bay coast and was moving north, and weakening. Rainfall continued around the Sunshine coast hinterland, the Gold Coast hinterland, eastern Darling Downs, Capricornia and Wide Bay districts. The southern quarter of the state recorded the heaviest rainfall in the first week of the month.

Up to 9am on the 9th, some very high daily totals of around 260 to 300 mm were recorded in the North Tropical Coast due to a firm ridge along the east coast directing moderate to fresh southeast winds and showers into most east coast districts. Meanwhile, an inland trough over the far south west of the state and an upper trough near the western border generated a cloud band, which brought some moderate to heavy falls overnight on the 9th and into the 10th. Century Mine received 76 mm up to 9am on the 10th.

During the 11th, a cloud band with embedded storms generated falls in the southern and central interior, and a mid level trough remained near stationary around the Queensland and Northern Territory border which continued to produce moderate to heavy falls and thunderstorms. Some sites had their highest April daily rainfall on record.

On the 13th, a surface trough was lying near the Capricornia and southeast Queensland coast with an upper level trough located over the southern interior.  In the afternoon, flood warnings were issued for coastal streams between Rockhampton and the Gold Coast, and severe weather warnings were issued for the Capricornia, Wide Bay, Burnett and Southeast coast districts. Moderate to locally heavy falls occurred about most of the east coast, particularly the southern Wide Bay and southeast coast region. Teddington Weir TM recorded 281 mm and Goomboorian TM recorded 275.6 mm to 9am on the 14th. 

From available figures, the highest monthly rainfall was recorded at Bellenden Ker Top station with 836 mm, then Eerwah Vale with 616.6 mm, then Cooroy Composite with 607.9 mm, followed by Cooran TM with 558 mm. Some sites had their highest total April rainfall on record and some sites had their highest total April rainfall for at least 20 years.

Notes

This statement has been prepared based on information available at 10 am on Friday 1 May 2009. Some checks have been made on the data, but it is possible that results will change as new information becomes available.

Please note that the rainfall data from Bureau of Meteorology telemetry gauges (those with ALERT, AL or TM in their names) includes real-time operational data from automated systems and has not been checked.

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 temperature anomaly maps are calculated with respect to the reference period 1961−1990. The rainfall decile maps are based on a reference period comprising all gridded analyses from 1900 to the present available at the time the deciles are calculated

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, 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.
