Adelaide is heading into a mostly fine start to the week, with sunshine and mild daytime temperatures sticking around before a wetter and cooler change moves in from Tuesday and lingers into next weekend.
Sunday is shaping up as a pleasant end to the weekend across Adelaide, with mostly sunny skies and light winds helping the city reach around 19 degrees. Monday looks even better if you’re making outdoor plans, with a sunny day forecast and temperatures lifting to 21 degrees. There is a small chance of morning fog around the hills, but for most of the metro area it should be a clear and calm start before light winds turn north to northeasterly later in the day.
The change arrives on Tuesday, which begins mostly sunny before cloud builds and showers become more likely through the afternoon. Adelaide is forecast to reach 22 degrees before winds pick up, shifting from the north and northwest to a west-southwesterly change later in the day. It is the first real sign of a more unsettled run of weather for the city, and it will be worth keeping an umbrella handy if you’re out and about later.
By Wednesday, temperatures take a noticeable dip, with Adelaide dropping to a top of just 16 degrees under cloudy skies and a medium chance of showers. The breezy west to southwesterly flow will make it feel cooler again after the mild start to the week, marking a sharp contrast to Monday and Tuesday’s above-average temperatures.
The second half of the week stays fairly grey. Thursday is expected to remain cloudy with a high chance of showers and a top of 17 degrees, while northwesterly winds continue to push moisture across the city. Friday looks slightly warmer, climbing to 21 degrees, but it also carries the highest rain chance of the week, with showers likely and up to 7mm possible. By Saturday, conditions ease only slightly, with cloud sticking around, another chance of showers, and a cooler top of 17 degrees.
Overall, Adelaide residents can expect a classic early spring pattern: a bright and comfortable opening, then a run of cooler, changeable days as fronts move through. For anyone planning events, or evenings out, the best weather appears to be Sunday and Monday, while the wettest stretch is likely from Tuesday afternoon through Saturday.
Across the rest of South Australia, the broad picture is similar, although regional conditions will vary more sharply. Sunday and Monday will bring dry and mostly sunny weather to much of the state, with morning fog developing on and east of the Mount Lofty Ranges and frost patches possible in the southeast. Some fog is also possible over parts of Eyre and Yorke Peninsula on Monday morning. Temperatures are expected to sit above average through the first half of the week, especially ahead of the Tuesday front.
That front will bring isolated showers to the Agricultural Areas during Tuesday, along with fresh and gusty winds, particularly near the coast and through the ranges. By Wednesday, showers are expected to linger about the Southern Agricultural Area, while northern districts stay comparatively warmer. Rainfall totals through to the end of Wednesday are forecast to be light to moderate, mostly 1 to 5mm across the Agricultural Areas, increasing to 5 to 10mm in the Lower South East, with locally higher falls possible around windward coasts and ranges.
For coastal communities and anyone heading out on the water near Adelaide, conditions stay calm through Sunday and Monday with light winds, slight seas and a low swell. Tuesday brings a more noticeable change, with northerly winds of 15 to 20 knots shifting west to southwesterly in the evening, and seas building to 1 to 1.5 metres south of Port Noarlunga. Wednesday remains cloudy with southwesterly winds easing westerly and seas around 1 metre.
