New South Wales in May 2020: cool conditions persist, but below average rainfall

Daytime temperatures were below average across New South Wales for the fourth consecutive month, extending a sequence not seen since 2011–2012. However, rainfall was below average over much of the State except for parts of the Central and North West Slopes districts.

Below average rainfall

  • May rainfall was below average across much of the State, particularly in the Western Districts and along the south coast
  • State-wide, the average total rainfall was 22.06 mm, less than 50% of the long-term average and comparable to May 2018
  • Parts of the Central and North West Slopes districts were wetter than average, mainly from the passage of cold fronts on the 1st and 21st
  • A few sites had their highest May daily rainfall on record or their highest total May rainfall for at least 20 years

Cool conditions persist

  • Both daytime and night-time temperatures were below average across virtually the entire State, reaching 1–2 degrees below the long-term average in parts of the west
  • May was the State's fourth consecutive month of below average mean maximum temperatures, a sequence not seen for New South Wales since 2011–2012
  • The state-wide maximum temperature was 0.70 °C below average, the coolest May since 2011
  • Many sites had their lowest May mean daily maximum temperature on record or their lowest since 2000
  • State-wide minimum temperatures were 0.72 °C below the long-term average, the lowest since 2012
  • Cold air from a frontal system passed over the State over 21–23 May, with Tamworth Airport AWS and Moree Aero recording their coldest May day (lowest maximum temperature) on record

Tasman Low 24–26 May with high surf

  • A deep low-pressure system was in the Tasman Sea off the Illawarra and Sydney coast over 24–26 May
  • This brought damaging surf conditions to parts of the Sydney and South Coast, with waves of 5–10 metres reported, and some coastal inundation around Newcastle on the 24th
  • As the system was offshore, it did not bring significant damaging winds or heavy rainfall to mainland New South Wales

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 12 pm on Monday 1 June 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.
