Western Australia in 2022: Extreme heatwave in the Pilbara in January, a very wet spring
Western Australia above average annual rainfall in 2022 was largely due to the second-wettest spring on record. The state-wide annual maximum and minimum temperatures were above average, but it was the coolest daytime temperatures since 2011. Early in January, an extreme to severe heatwave was observed in the Pilbara with temperatures climbing over 50 degrees at multiple sites.
Above average rainfall in the north and eastern South West Land Division
- Annual rainfall was 22% above the 1961–1990 average, the wettest year since 2017 for Western Australia.
- Rainfall was above average for much of the northern WA and eastern parts of the South West Land Division; it was the seventh-wettest year on record for the Kimberley District.
- A monsoon trough and low pressure systems brought a number of highest annual daily rainfall records in the Kimberley in February; daily rainfall of 652.2 mm on the 1st at Country Downs was the state's second-highest annual daily rainfall, behind only 747 mm at Whim Creek on 3 April 1898.
- Tropical Cyclone Anika brought daily rainfall of 100–200 mm in the east Pilbara and far west Kimberley at the start to March.
- Ex-Tropical Cyclone Charlotte produced daily rainfall of 100–200 mm in the Gascoyne District at the end of March, several sites had their annual daily rainfall records on the 30th.
- Daily rainfall of 50–120 mm was recorded near the Gascoyne coast at the start to April; Carnavon recorded 118.6 mm on the 2nd, its highest daily rainfall in April, and its third-highest annual daily rainfall on record, behind 207.8 mm on 17 December 2010, and 137.2 mm on 5 February 2021.
- A slow-moving trough produced a number of annual daily rainfall records in the South East Coastal District on 13 and 14 April
- A cloudband and cold front produced daily rainfall of 25–70mm along the west Gascoyne and Central West districts on 16 August, including several annual daily rainfall records.
- Large parts of the Kimberley and the adjacent Northern Interior districts observed their highest spring rainfall on record, and in the top 10% of historical records for most of the northern half and south-east of the state, as well as along the south coast. It was the second-wettest spring on record for WA
Extreme heatwave with record breaking temperatures in the Pilbara
- The annual mean maximum temperature was 0.61 °C above the 1961–1990 average for Western Australia, although the year 2022 was the coolest since 2011.
- The annual mean minimum temperature was 0.38 °C above the 1961–1990 average for Western Australia.
- An extreme to severe heatwave was observed in the Pilbara and central Western Australia between 12 and 14 January, when maximum temperatures reached high 40s to over 50 °C including a handful of records
- Onslow Airport recorded 50.7 °C on 13 January, which equalled the all-time highest temperature in Australia; both Roebourne Aero and Mardie recorded 50.5 °C on the same day, ranking as the equal third-highest temperature in the country.
- Geraldton Airport in the Central West District recorded its all-time longest run (6 consecutive days) with maximum temperatures over 43 °C in 113 years of record in late January
- On the last day of May, wet and cloudy conditions over the northwest WA resulted in daytime temperatures in the low 10s, the annual coldest day on record for a number of sites in the Pilbara.

Notes
The Annual climate summary, generally published on the second working day of the year, lists the main features of the weather in Western Australia 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 12 pm on Tuesday 24 January 2023. 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.
