• Western Australia's area-averaged rainfall total in April was 22.6 mm, 8% above the 1961–1990 average.
• Several sites in the south and in the northern Kimberley recorded had their wettest April on record, or wettest April for at least 20 years.
• A number of slow-moving troughs brought thunderstorms with showers over central and south of the state at mid-April. Daily rainfall totals of 50–120 mm were recorded in and around the Southeast Coastal district on the 14th, including a number of highest April daily rainfall records.
• Erinair in the Southeast Coastal district recorded a daily rainfall of 100 mm on the 14th, which was not only its highest April daily rainfall on record, but also its second-highest annual daily rainfall in 58 years of rainfall observations, behind its annual record of 135 mm on 5 January 2007.
• Ex-severe tropical cyclone Errol crossed the Kimberley coast to the south of Kuri Bay on the 18th. Erroal and its remanent brought moderate to locally heavy daily rainfall to the north Kimberley.
• Kalumburu in the north Kimberley coast recorded 160.8 mm on the 19th, its highest April daily rainfall on record. Its monthly total of 252.8 mm was its wettest April on record.
• Hyden in the Great Southern District recorded its highest April rainfall on the 14th, and its second-wettest April on record, and the wettest April since 1942.

• Mean maximum temperatures in April were above to very much above average for a large part of the state, from the Pilbara and Gascoyne, down to the Lower West, extending east to central and southeastern WA.
• Below average mean maximum temperatures were confined in small areas to the Kimberley, and Southeast Coastal districts.
• Western Australia's area-averaged mean maximum temperature was 31.2 °C, 1.42 °C above the 1961–1990 average.

• Mean minimum temperatures in April were above to very much above average for most of the state, and close to average mean minimum temperatures were observed in the northeastern WA.
• Western Australia's area-averaged mean minimum temperature was 18.1 °C, 1.39 °C above the 1961–1990 average, the ninth-warmest on record for all Aprils since 1910.
• Western Australia had its highest mean minimum temperature for April since 2020.
• Western Australia's area-averaged mean temperature was 24.6 °C, 1.41 °C above the 1961–1990 average.
• Hot days and very warm nights were observed in the western parts of the state at the start of April. Maximum temperatures reached the low 40s in the Central West and southern Gascoyne on the 2nd, whist minimum temperatures were in the mid-to-high 20s in the state's northwest coast on the 3rd.
