Adelaide is heading into a changeable week of spring weather, with warm conditions easing into a cooler, cloudier weekend before temperatures lift again early next week. For locals planning beach walks, markets or a day in the hills, the headline is fairly simple: today and Friday look mild and mostly dry, Saturday is the best chance for showers, and another wetter change is shaping up by Wednesday.
For the rest of Thursday, Adelaide is expected to stay partly cloudy with just a slight chance of a shower about the hills and southern suburbs, most likely this morning. Elsewhere, rain chances are close to zero. The city is heading for a top of 26 degrees, with slightly warmer conditions through the northern suburbs including Elizabeth at 27, while Glenelg and Noarlunga are forecast to reach 24. Light winds will make for a fairly comfortable day after an earlier northeasterly flow, though UV levels will still be high through the middle of the day.
Friday brings a small dip in temperature, with Adelaide forecast to reach 23 degrees after an overnight low of 14. It should remain partly cloudy, with only a slight chance of a shower, and light winds becoming southeasterly later in the evening. It’s the kind of spring day that shouldn’t cause too much disruption, but it will feel noticeably cooler than the warmth many parts of the state are seeing inland.
That cooler shift becomes more obvious on Saturday. Cloud is expected to build across Adelaide, with a medium chance of showers and a top of just 20 degrees. Between 0 and 3 millimetres is possible, and southeasterly winds of 20 to 30 km/h will add to the chill. If you’re heading out, this looks like the day to keep a jacket and umbrella handy.
By Sunday, conditions improve a little but remain unsettled. Adelaide is forecast to reach 21 degrees under partly cloudy skies, with a slight chance of a morning shower. There is also the chance of a thunderstorm about the northern suburbs in the afternoon, so it’s worth keeping an eye on the sky if you’re spending time outdoors. East to southeasterly winds will stay brisk at 20 to 30 km/h.
Looking into next week, Monday shapes up as a more settled and pleasant day, with partly cloudy skies and a top of 25 degrees after a cool overnight minimum of 11. Easterly winds will turn northeasterly later, helping temperatures climb further on Tuesday. That day is forecast to reach 27 degrees, with partly cloudy conditions and just a slight chance of a shower later in the day. By Wednesday, the next change arrives, bringing a high chance of showers and a cooler maximum of 24 degrees.
Across regional South Australia, the broader pattern is being driven by a slow-moving trough over the west of the state, while a ridge of high pressure shifts away to the east. That setup is keeping inland areas unusually warm for this time of year, with maximum temperatures well above average through much of the north and interior through the weekend. Coastal districts, including western and southern parts of the state, are more likely to see isolated showers, with a few thunderstorms possible in the far southwest, Eyre Peninsula, Yorke Peninsula and Kangaroo Island on Friday, and again in the far west on Saturday. Rainfall totals are generally expected to stay low, though local falls of 10 to 20 millimetres are possible about the far southwest, Kangaroo Island and the Lower South East. For Adelaide boaters, metropolitan waters remain relatively calm, though southeasterly winds will freshen on Saturday and Sunday.
