New South Wales in July 2018: much drier than average with warm days and cool nights

Rainfall was very much below average for most of New South Wales in July 2018, except in the northeast. Daytime temperatures were very much warmer than average, while night time temperatures were mostly cooler than average, including areas of coldest on record in parts of the northwest.

Much drier than average

  • Fifth-driest July on record and driest since 2002 for New South Wales as a whole
  • Drier than average across all but the northeast which was generally close to average
  • Much of the State's northwest had little or no rain for the month
  • Many sites had either their lowest total July rainfall on record or their lowest total July rainfall for at least 20 years
  • Fewer or weaker rain-bearing systems crossed New South Wales, with more high pressure systems influencing the State's weather
  • July 2018 continued a run of seven consecutive months of below average rainfall for New South Wales as a whole
  • NSW had its driest January to July period since 1965
  • Longer term rainfall deficiencies in New South Wales increased in severity and spatial extent
  • The highest totals were observed in parts of the northeast and South West Slopes and Snowy Mountains where monthly totals exceeded 40 mm
  • In the Northern Tablelands, there was heavy rain early in the month with July totals there close to average; Point Lookout had its highest July daily rainfall on record and its highest total July rainfall on record
  • The highest recorded total for the month was 171.2 mm at Perisher Valley
  • July 2017 was also much drier than average in many parts of New South Wales

Warm days, cool nights

Strong winds at times, and snow

  • Thredbo recorded the highest wind gusts of the month with a gust of 126 km/h on the 29th, followed by gusts of 120 km/h on the 5th, 6th, and 17th, all with cold fronts

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 11 am on Wednesday 1 August 2018. 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.
