Victoria in May 2024

Rainfall

• Victoria's area-averaged rainfall total for May was 29.74 mm, which was 55.3% below the 1961–1990 average. It was the lowest May rainfall total for Victoria since 2009.
• The May area-averaged rainfall total for Victoria was below average for most of the west, south and east, and above average for parts of the far north.
• Goulburn River at Seymour in the North Central district had its highest total May rainfall on record at 92.2 mm.
• A deep interior trough extended into Victoria on the 10th and a strong cold front that crossed the state on the 31st resulted in many sites having their highest May daily rainfall on record.

Temperature

• The area-averaged May mean temperature was 11.53 °C, which is 0.29 °C above the 1961–1990 average.
• May mean temperature for Victoria was above average for the central third of the state, and very much above average relative to all Mays since 1910 for parts of the north-east.
• The area-averaged May mean maximum temperature for Victoria was 17.52 °C, which was 1.53 °C above the 1961–1990 average. It was the 7th highest state mean maximum temperature on record.
• May mean maximum temperature was above average for all the state, and very much above average relative to all Mays since 1910 for the northern two thirds of the state.
• Many stations in the far north-east had their highest May mean daily maximum temperature on record. This was in part due to predominant high pressure systems bringing clear sky, which allowed the surface to warm rapidly during the day.
• The area-averaged May mean minimum temperature was 5.55 °C, which was 0.95 °C below the 1961–1990 average, and it was the lowest since 2006.
• May mean minimum temperature in the west of Victoria was very much below average relative to all Mays since 1910.
• Many stations had their lowest May mean daily minimum temperature on record. This was partly due to predominant high pressure systems bringing clear sky which allowed the surface to lose heat rapidly at night, additionally, many strong cold fronts pushed cold air into Victoria in the second half of the month.

Notes

The Monthly climate summary, usually published in the first week of the following month, lists 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.

This statement has been prepared based on information available at 8 am on Sunday 2 June 2024. Some checks have been made on the data, but it is possible that results will change as new information becomes available.

In some situations, some or all of the rainfall is in the form of hail or snow. In these cases the totals given are for the water equivalent: the depth of liquid water that results from melting any frozen precipitation. There can be significant 'undercatch' of snow in strong winds, meaning the true precipitation can be higher than that reported.

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.

Where temperature area averages are mentioned, they are derived from the ACORN-SAT dataset.
