Western Australia in September 2016: Unusually cold in the south, hot in the far north

September 2016 rainfall was generally near average to below average across much of the State, but above average in parts of the Kimberley. Most of WA recorded cooler than normal daytime and overnight temperatures, apart from the far north of the State, and both mean maximum and minimum temperatures for the whole State were below average as a result. The South West Land Division (SWLD) in particular recorded unusually low temperatures and the mean minimum temperature for the month was the lowest in September on record.

Below average to near average rainfall for most of WA; above average rainfall in parts of the Kimberley

• WA September rainfall was near average
• Kununurra Aero (north Kimberley) had its wettest September on record, and a number of other Kimberley sites had their wettest September in more than 30 years as a result of thunderstorms and cloudbands

Cooler days and nights for most WA; hot in the far north

• The mean maximum temperature for WA was about 0.5 °C below average and the coolest September for six years, since 2010
• The SWLD mean maximum temperature was about 1.4 °C below average, the equal tenth-coolest September on record
• The mean minimum temperature for WA was about 0.7 °C below average and the lowest for five years, since 2011
• The SWLD mean minimum temperature was about 2.1 °C below average and the lowest in September on record
• Unusually hot conditions in the Kimberley set several daily and monthly temperatures records
• Wyndham Aerodrome (Kimberley) recorded Australia's highest mean maximum temperature on record in September (39.2 °C), including ten days with daily maxima of 40 °C or higher, which is also a national record for the number of such days in September
• Other extremes in the Kimberley including hottest September day at Argyle Aerodrome on the 27th, record high September mean maximum temperature at Warmun, and highest September mean maximum since 1992 at Doongan
• A daily minimum temperature of 30.0 °C at Warmun on the 30th was a national record for the highest minimum temperature in September; a few other sites in the Kimberley also had their warmest September night on record
• Broome Airport and other Kimberley sites recorded their highest September mean minimum temperature on record; only old Broome Post Office site's mean minimum temperature of 21.4 °C in September 1910 was higher than the Broome Airport's new record
• In contrast to the north, a number of sites in southwest WA had their lowest September mean maximum temperature on record, and many sites in the southern half of WA had their coldest September since 1992
• Several sites across southern WA recorded their coldest September night on record during the month, whilst numerous sites in western and southern WA registered their lowest September mean minimun temperature on record
• A high number of very cold nights were observed in the SWLD during the month; Cunderdin Airfield (Central Wheat Belt) recorded eight times with minimum temperatures 0 °C or lower, which was its highest number of such nights in September in 67 years of record

Frost in the South West Land Division (SWLD)

• Freezing temperatures caused significant frost damage to crops in parts of the SWLD in mid-to-late September
