Safety Advice::
Extreme heatwaves can be dangerous for everyone.
Severe heatwaves can be dangerous for many people, especially older people, babies, children, pregnant and breastfeeding women, people with medical conditions and people who are unwell.
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 high thirties to the mid forties, and overnight minimum temperatures mostly in the low to high twenties.
Extreme heatwave conditions are forecast over the Goldfields and South Interior districts.
Severe heatwave conditions are persisting over much of southern and inland WA, and are gradually easing over western districts as milder onshore flow develops. A further contraction of severe heatwave conditions to the north of the state is expected over the weekend as these milder conditions push further inland.
Severe heatwave conditions have eased in the South West district. Locations likely to be impacted include Esperance, Kalgoorlie, Kiwirrkurra, Meekatharra, Mount Magnet, Mount Barker, Merredin, Newman, Northam and Port Hedland.
The next heatwave warning will be issued by 2:00pm WST on Saturday 25 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.
