Victoria in March 2015: a cool and dry month

  • March was a relatively cool month for most of Victoria, and rainfall was below average in most areas away from the coast.
    • Mean overnight temperatures below average, and well below average in the west
    • Mean daytime temperatures below average, especially in the west
    • Rainfall below average in most areas, especially in the north
    • Above-average rain on the southwest coast

Overnight minimum temperatures were below average for most of Victoria in March, and well below average in parts of the southwest; some sites had their lowest March mean daily minimum temperature. Daytime temperatures were average or below average for most of the State. There was some particularly cool weather from the 24th to the 26th (with a few sites setting new low temperature records), but there were also warm days (with the 19th the warmest at most sites). The statewide mean minimum temperature was 1.20 C below the March average of 11.75C, and the statewide mean maximum temperature was 0.61 C below the average of 24.75C. This is in marked contrast to the generally warm February.

Rainfall was below average for most of the State, with some pockets in the north well below average. Some areas on the southwest coast had somewhat above-average rain. This follows a generally dry February but a quite wet January.

Notes

A Monthly Climate Summary is prepared to list the main features of the weather in Victoria using the most timely and accurate information available on the date of publication; it will generally not be updated. Later information, including data that has had greater opportunity for quality control, will be presented in the Monthly Weather Review, usually published in the fourth week of the month.

A Climate Summary is generally published on the first working day of each month.

This statement has been prepared based on information available at 10 am on Wednesday 1 April 2015. Some checks have been made on the data, but it is possible that results will change as new information becomes available.

Averages for individual sites 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 long-term average 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, 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.

The ACORN-SAT dataset is used for temperature area averages.
