Western Australia in February 2018: A wet month with below average daytime temperatures

February 2018 was particularly wet in the west Kimberley and southeast of Western Australia, with little rainfall recorded near the west coast. For the State as a whole, rainfall was above average, whilst the WA mean maximum temperature was below average and the WA mean minimum temperature was near average.

Above average rainfall for WA

• Monthly rainfall was above average for WA, but lower than February 2017 as it ranked eighth-wettest February on record
• The South West Land Division also recorded above average rainfall
• Tropical cyclone Kelvin produced very heavy fall in the west Kimberley in mid-February; a daily rainfall of 376.8 mm at Broome Airport on the 17th is not only its February record, but also highest February daily rainfall in WA for 23 years since 10 February 1995 when 415.8 mm was recorded at Balmoral in the Pilbara
• Thunderstorms produced isolated moderate to heavy rainfall in inland WA on the 11th, and the South West Land Division on the 25th and 26th, resulting in a few February daily rainfall records
• A record high February rainfall at Broome Airport followed a record wet January; the two-month rainfall total (1559.4 mm) exceeded the previous annual rainfall record (1496.6 mm set in 2000)
• Mount Elizabeth on the Kimberley Plateau also had its wettest February on record while a few sites in the west Kimberley, Gascoyne, eastern South West Land Division, and Eucla had either their wettest February on record or wettest February rainfall in over 20 years

Mean maximum temperatures below average for much of WA

• Mean maximum temperature was 1.15 °C below average for WA
• Mean minimum temperature was 0.19 °C below average for WA
• Mean maximum temperatures were 2 °C to 3 °C below average along the west coast and west Pilbara coast, and 2 °C to 4 °C below average in large parts of northern and eastern WA; several sites near the west coast and in the west Kimberley had their mildest February on record or mildest February for at least 20 years in terms of maximum temperatures
• The passage of tropical low 11U resulted in daytime and overnight temperatures well below average in northern and central WA on 1 February; Telfer and Newman in the Pilbara had record low minimum temperatures, and Laverton and Leinster in the Goldfields had record low maximum temperatures
• Tropical cyclone Kelvin brought cloud and heavy rain to the west Kimberley in mid-February, and Broome Airport, Derby Aerodrome, and Curtin Aerodrome registered their coolest day in February on record on the 16th as a result
