New South Wales in December 2019: a cool start, then record hot and very dry

Almost all of New South Wales experienced record high temperatures during December, with repeated bursts of very hot days. Rainfall was below average across the State, and record low for many areas, including Sydney. Smoke from numerous large fires led to reduced air quality for much of the State

Another dry month

  • The New South Wales total rainfall was 85% below average, the second-lowest for December with only 1938 drier
  • Rainfall was below average for almost the whole State, with a large swathe seeing less than one-fifth of typical December rain
  • Record low rainfall was reported in a region from the Hunter to the Illawarra, and inland through the Central and Southern Tablelands, as well as patches in the Central and Upper Western regions
  • Numerous sites had their lowest total December rainfall on record or their lowest for many years
  • Patches of the Upper North Coast district were the only areas to have close to average rain for December, having had moderate falls at the start of the month, around the 12th and again around the 25th

A cold start, then record heat

  • A spell of cold weather at the start of the month gave a few inland sites their coldest December day on record, and a few others their lowest December temperature on record
  • Several inland sites had their highest December temperature on record on the 10th or 11th, but most of those new records were broken again between the 20th and 22nd when numerous sites had their highest December temperature on record (and in some cases the highest for any month) and temperatures over 47 °C were reported in the west
  • Another burst of heat reached the west on the 27th before extending eastwards, bringing record high temperatures around Sydney on the 31st
  • The bursts of hot days also saw record warm nights (highest daily minimum temperature) at some sites, mostly in the southeast inland
  • The hot days meant many sites had their highest December mean daily maximum temperature on record or their highest December mean temperature on record, but cool nights at the start of the month meant only a few sites had their highest December mean daily minimum temperature on record
  • Nearly all of New South Wales recorded its highest accumulated monthly Forest Fire Danger Index for December, with highest on record daily values for December occurring west of the Riverina and across the Monaro regions of southern NSW on the 30th or 31st
  • The mean temperature for New South Wales was the highest on record for December at 3.32 °C above average, about 0.4 °C warmer than the previous highest from 2018
  • The State's mean maximum temperature was the highest on record for December at 4.31 °C above average, almost 1.4 °C warmer than the previous highest from 1990
  • The State's mean minimum temperature was the third-warmest for December at 2.34 °C above average

Notes

The Monthly climate summary, generally published on the first working day of each month, lists the main features of the weather in New South Wales using the most timely and accurate information available on the date of publication; it will generally not be updated. More extensive discussion of significant weather events, along with later information and data that has had greater opportunity for quality control, will be presented in the Monthly Weather Review.

This statement has been prepared based on information available at 3 pm on Monday 6 January 2020. 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.
