Adelaide is heading into a varying week, with a warm start today and tomorrow before cooler, showery conditions settle in later in the week. For people planning long weekend outings, trips or time by the coast, it’s a week that looks set to swing from mild autumn warmth to a much cooler, windier finish.
Today, Sunday, will stay partly cloudy across Adelaide, with showers becoming more likely from late this morning. The city is tipped to reach 27 degrees, with up to 5mm possible, and nearby suburbs such as Elizabeth could climb to 28 degrees. It’s a fairly gentle start in terms of wind, with northeasterlies easing early, but the chance of rain sits high enough that it’s worth keeping an umbrella handy if you’re out and about.
Monday keeps the warmth going, with a mostly sunny morning before the chance of a shower or two returns later in the day. Adelaide is forecast to reach 28 degrees after an overnight low of 18, though a wind shift around the middle of the day will mark the start of a change. Northerly winds will swing west to southwesterly, and that cooler push will help knock temperatures back on Tuesday.
By Tuesday, Adelaide drops to a top of 23 degrees, with a possible morning shower under partly cloudy skies. Southwesterly winds will keep things feeling fresher, and while rainfall totals look light, it will be a noticeable step down from the warmer start to the week. Wednesday stays in a similar pattern, with a top of 24 degrees, a low of 13, and a medium chance of showers through the morning and afternoon.
The second half of the week looks wetter and colder. Thursday brings the highest chance of rain in the seven-day forecast, with showers expected and even the chance of a thunderstorm. Adelaide is forecast to reach 25 degrees, but the weather will feel less settled as northerly winds turn west to northwesterly and strengthen through the morning. Friday then takes a sharper turn into cooler autumn weather, with a top of just 18 degrees, cloudy skies and a high chance of showers. Westerly winds shifting southwesterly at 25 to 35 km/h will add to the chill.
Saturday looks set to stay cool, cloudy and breezy, with just a possible shower and a top of 17 degrees after a low of 10. Southwesterly winds will ease slightly as they turn southerly during the day, but it’s shaping up as a much cooler end to the week than the one Adelaide starts with today.
Across regional South Australia, the broader pattern follows a similar story, although conditions will vary sharply between the north and south. The far north is expected to stay mostly sunny through the first half of the week, with temperatures above average, while southern parts of the state see more cloud, isolated showers and the risk of thunderstorms, especially about the southwest and southern coasts. Rainfall totals are generally expected to stay low across much of the agricultural area, though the Bureau says 2 to 10mm is possible about the southwest and southern coasts and ranges, with isolated heavier falls of 10 to 30mm possible in thunderstorms. Coastal areas can also expect some shifting winds as fronts and troughs move through, while marine conditions around Adelaide Metropolitan Waters remain relatively modest through midweek, with seas mostly below 1 metre.
