What does “hot weather” mean in Australia?
The Bureau of Meteorology (BOM) uses a heatwave severity scale that ranks hot weather into three levels: low-intensity, severe, and extreme. The threshold for “hot” can differ between coastal and inland regions – for example, hot weather Sydney may feel different to hot weather Adelaide due to humidity. The practical takeaway is that any day forecast above 35°C requires extra care, especially if it follows several consecutive hot days.
