New South Wales in October 2015: Warmest October on record

October 2015 was the warmest on record for NSW, with a significant early-season heatwave followed by persistently warm conditions across the State. Rainfall was below average, despite locally heavy falls associated with thunderstorms in the second half of the month.

  • Warmest mean, maximum and minimum temperatures on record for NSW
  • Heatwave breaks early-season temperature records in southern NSW
  • Below average rainfall across the State

New South Wales had its warmest October on record in 2015, with the statewide average temperature 4.52 °C above the historical average and 1.94 °C above the previous record, set in October 2014. Both maximum (+5.50 °C) and minimum (+3.54 °C) temperatures were the warmest on record for NSW, with a large number of stations breaking records for monthly maximum, minimum, and mean temperatures.

The highest temperatures were experienced during a significant and prolonged heatwave at the start of the month, with some stations in southern NSW recording their warmest October day on record and many others breaking early-season records or experiencing a record spell of consecutive warm days. More information on this event is available in Special Climate Statement 52. Well above average temperatures continued for most of the month, with numerous stations breaking October records for the total number of days exceeding 25 °C or 30 °C.

The statewide average rainfall during October was 51% below the historical average. Rainfall was generally below average to well below average in the south and west and closer to average in the northeast. Most of the rain that fell was associated with thunderstorms, particularly during 21-22 and 26-27 October, with some localised heavy rainfall along the coast.

Notes

The Monthly climate summary 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. Later information, including data that has had greater opportunity for quality control, will be presented in the Monthly Weather Review.

A climate summary is generally published on the first working day of each month.

This statement has been prepared based on information available at 8 am on Monday 2 November 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.
