Western Australia in November 2018: wet in central and southeast

Rainfall was above average across a broad area from the east Gascoyne, through central to southeast Western Australia, while rainfall was either below average or close to average near the west coast and for most of the South West Land Division. Mean maximum temperatures were above average in the Kimberley and surroundings, while most of the State's southwest quadrant, and the west Pilbara coast had cooler than normal mean maxima. Mean minimum temperatures were above average for much of the eastern half of WA, with below average mean minima confined to the far southwest.

Wet across the central and southeast WA

• Rainfall was above average and the wettest since 2014 for the State as a whole; it was the wettest November since 2015 for the South West Land Division (SWLD)
• A developing trough produced thunderstorms with moderate to heavy rainfall across inland WA from the Gascoyne, eastern SWLD to Goldfields on the 10th and 11th; a number of November daily rainfall records were broken as a result
• Allan Rocks in the Central Wheat Belt reported a November record of 107 mm on the 11th, which is also its third-highest all-time daily total, behind 117.1 mm on 17 February 1970 and 110.0 mm on 8 February 1996
• A number of sites in inland Gascoyne and Goldfields had their wettest November on record , or wettest November for at least 20 years due to thunderstorms
• Perth Metro, and a number of sites near the west coast and in the north had either their driest November on record or driest November for at least 20 years

Above average temperatures in the Kimberley

• For WA as a whole, mean maximum and minimum temperatures were above average though it was the coolest November since 2011
• For the SWLD as a whole, the mean maximum temperature was close to average whilst the mean minimum temperature was slightly below average, but both was the coolest November since 2008
• In terms of mean maximum temperature, Kalumburu in the Kimberley had its warmest November on record, whilst Swanbourne and Rottnest Island in the Perth area had its mildest November on record
• In terms of mean minimum temperature, Cygnet Bay and Doongan in the Kimberley had their warmest November on record, while Jarrahwood and Shannon in the southwest had their coolest November on record
• Light winds and clear skies in the wake of cold southerly winds had several sites in the southwest recorded their lowest November temperature on the 7th

Grain crops lost by fires

• Fires sparked by lightning destroyed grain crops in Dalwallinu Shire on the 16th, with an estimated $3.6 million damage bill
