Western Australia in September 2022: Wettest September on record for parts of the Pilbara and Gascoyne

Rainfall in September was 30% above average for Western Australia as a whole. It was the highest September rainfall since 2010 and the third-highest September rainfall on record (since records began in 1900). Large parts of the Pilbara and Gascoyne districts received their highest September rainfall on record. Monthly totals were very much above average into the Goldfields and most of the Southern Interior and Kimberley districts. Temperatures were below average for Western Australia as a whole. Daytime temperatures were the coolest since 2016 and cooler than average everywhere apart from the Kimberley, Northern Interior and South West districts. Nights were warmer than average almost state-wide with parts of the Kimberley up to 4 °C above average.

A very wet September

• For Western Australia as a whole, September rainfall was 30% above average.
• Rainfall in the top 10% of historical records was recorded across approximately two-thirds of the State.
• It was the wettest September since 2010 and the third wettest September overall.
• On 3 September, as a trough associated with a low pressure system crossed the Gascoyne, 15% of Western Australia's area experienced its highest September daily rainfall on record.
• A cloud band associated with this trough produced moderate to heavy rainfall (30 to 60mm) and thunderstorms over the southern Pilbara and Gascoyne.
• A flood watch was issued for the Gascoyne Coast and Southern Pilbara with localised flooding occurring.
• Numerous secondary roads were closed and both the North West Coastal and Great Northern Highways had water over the road in places (though roads were not closed to any vehicles).
• Rainfall totals for the first 7 days of September were 40-80 mm in the inland Pilbara, Gascoyne, Central West, Lower West and Central Wheat Belt; about 10 times the September average, making it already the wettest September on record.
• Inland storms brought more than 25 mm rainfall to the Southern Interior on 11 September.
• A cold front brought more than 25 mm rainfall to the South West on 13 September.
• A slow-moving upper low over the Gascoyne brought unseasonal showers and thunderstorms to the Kimberley and Interior on 30 September.
• Many sites had their highest September daily rainfall on record.
• Many sites had their highest total September rainfall on record or their highest total September rainfall for at least 20 years.

Close to average temperatures

• The mean maximum temperature for Western Australia for September 2022 was 0.13 °C below the 1961-1990 average and the coolest since 2016.
• Daytime temperatures for September were generally warmer than average in the state's north.
• The mean minimum temperature for Western Australia for September 2022 was 0.99 °C above the 1961-1990 average.
• Extreme fire danger rating occurred over the Eucla and Southern Interior on 12 September. Maximum temperatures in the mid 30 °Cs were seen in the Interior on 13 and 14 September - up to 8 °C above average.
• Four sites recorded in Western Australia's top ten highest temperatures on record. Wyndham Aero has a record count (14 days in total) and the longest run (13 consecutive days) with maximum temperature equal to or hotter than 40 °C for September.
• Several sites had their highest September temperature on record.
• Cunderdin Airfield, Newman Aero and Southern Cross Airfield had their coldest September day (lowest maximum temperature) on record on 3 September due to extensive cloud streaming from a low pressure system off the Gascoyne coast.
• Meekatharra Airport had its lowest September mean daily maximum temperature for at least 20 years.
• Cygnet Bay, Denham and Marble Bar had their warmest September night (highest daily minimum temperature) on record.
• Northam and Doongan had their highest September mean daily minimum temperature on record.
• Carnegie had its lowest September mean daily minimum temperature on record.
