Overview
- Bureau of Meteorology heatwave warnings, including severe alerts, are active across multiple Western Australian regions such as the Pilbara, Gascoyne, Goldfields, Eucla and the Central Wheatbelt.
- Heat is forecast to build over WA through Monday and Tuesday before pushing into South Australia on Tuesday and reaching Victoria and New South Wales from mid‑week.
- Numerous model runs indicate inland peaks in the mid‑to‑high 40s, with some guidance suggesting isolated spots could reach about 48°C.
- Adelaide may hit about 41°C and Melbourne could reach around 40°C, while inland centres like Mildura are forecast near 45°C late in the week.
- BoM expects parts of every mainland state and territory to exceed 40°C by Thursday, with severe to extreme heatwave conditions likely inland and warmer nights limiting relief; Perth stays comparatively cooler near the low 30s, and separate flood warnings are current for parts of Queensland.
