Seek a place to keep cool, such as your home, a library, community centre or shopping centre.
Close your windows and draw blinds, curtains or awnings early in the day to keep the heat out of your home.
If available, use fans or air-conditioners to keep cool.
Maximum temperatures ranging from the mid thirties to the mid forties and overnight minimum temperatures mostly in the low to high twenties.
Extreme heatwave conditions are forecast over the Central Wheat Belt, Great Southern, Goldfields and South Interior districts.
Severe to Extreme heatwave conditions are expected to persist over much of southern and inland WA this week, and gradually ease over the western districts by the weekend as milder onshore flow develops. A further contraction of Severe heatwave conditions to the north of the state are expected by the start of next week as milder southeasterly winds return to the south. Locations likely to be impacted include Perth Metropolitan Area, Bunbury, Geraldton, Gingin, Kalbarri, Meekatharra, Mount Magnet, Mandurah, Manjimup, Margaret River, Newman and Northam.
The next heatwave warning will be issued by 2:00pm WST on Thursday 23 January 2025

ENSO status: La Niña-like conditions. IOD status: Neutral. SAM status: Negative. Trending slightly negative. The El Niño Southern Oscillation (ENSO) is in a La Niña-like pattern. Recent conditions show some atmosphere-ocean coupling, resulting in the US declaring a La Niña event has started. A La Niña typically increases rainfall over northern and eastern Australia, while reducing rainfall over southern coastal Australia and western Tas. The Indian Ocean Dipole (IOD) is in a neutral phase and does not play a part in Australia's climate during this time of year. The Southern Annular Mode (SAM) is in a negative phase. Recent forecasts show negative SAM is more likely to dominate for the remainder of summer, due to the polar vortex taking an unusually long time to recover from the stratospheric warming event in winter 2024. During summer, a negative SAM decreases rainfall over most of southeastern Australia, and increases rainfall for far southwest WA and western Tas. Rainfall outlooks are showing above average rainfall over large parts of the country during summer, with closer to average conditions for the southwest corner of WA, southern SA and Vic, and central parts of Tas.
