Adelaide is set for a hot, mostly sunny run to start the week, with temperatures pushing into the mid-30s before a midweek change brings cooler conditions, cloud and a chance of showers. Sunday remains bright and dry with a top of 36°C, while strong UV levels and high fire danger in the Mount Lofty Ranges reinforce the need for sun protection and caution outdoors.
The heat holds into Monday, again reaching 36°C under mostly sunny skies, before a trough and cold front begin to influence conditions across the state. Tuesday shifts the pattern, with a shower or two possible, a medium chance of rainfall and the risk of thunderstorms through the morning and afternoon as winds turn and a cooler change moves through.
By Wednesday, temperatures drop sharply to the mid-20s, with partly cloudy conditions replacing the early-week heat. The back half of the week then stabilises into classic late-summer weather, with sunshine returning Thursday and building warmth into Friday and Saturday, both forecast to sit comfortably in the low-to-mid 30s.
Across South Australia, a ridge of high pressure is keeping conditions settled to begin with, before a trough and cold fronts move through Tuesday and Wednesday, bringing showers, isolated thunderstorms and below-average temperatures in some regions midweek. Rainfall totals are expected to remain relatively light overall, though isolated pockets may see slightly higher falls.
Fire danger is elevated in parts of the Mount Lofty Ranges, and changing winds ahead of the midweek front may create rapidly shifting local conditions.
