Adelaide weather forecast for Wednesday September 23rd and the days ahead

Happy Wednesday! Here’s the weather for September 23rd and a look at what’s to come for the rest of the week.

This week will be mostly mild and settled here in Adelaide, with sunshine, climbing temperatures and only a small chance of showers before a slightly wetter change edges in early next week.

The city’s run of calm spring weather starts on Wednesday with mostly sunny skies and a top of 25 degrees. Light winds through the middle of the day will make for a pleasant afternoon around town, before easterly to northeasterly breezes return later. Thursday looks to be the warmest day of the immediate stretch, reaching 28 degrees under partly cloudy skies. Northeasterly winds will tend northerly through the morning before easing off around midday, helping keep conditions comfortable rather than blustery.

Friday brings a slight dip in temperature back to 25 degrees, with partly cloudy conditions and just a slight chance of a shower. It does not look like a washout by any measure, but there may be enough cloud around to take the edge off the warmer start to the week. By Saturday, Adelaide stays partly cloudy with a top of 24 degrees, while southeasterly winds pick up to 15 to 25 km/h before turning easterly in the evening.

Sunday continues the settled pattern, with another partly cloudy day and temperatures lifting to 26 degrees. Easterly winds are expected to stay in the mix, keeping that familiar spring feel across the suburbs and along the coast. Monday then shapes up as the warmest day of the seven-day outlook, with Adelaide forecast to reach 29 degrees under partly cloudy skies. Easterly winds will turn northeasterly during the morning, adding to the warmer feel across the metro area.

By Tuesday, the pattern becomes a little more changeable. Showers are back in the picture, with a medium chance of rain and possible falls of up to 4 mm. The top is expected to reach 27 degrees before winds shift westerly during the day, marking the clearest sign yet that the settled run may be starting to break.

For Adelaide residents, it’s a fairly easy week to plan around. There is no sign of significant rain in the short term, and most days will be dry, partly cloudy and mild to warm. UV levels are still worth keeping an eye on too, with sun protection recommended on Wednesday from 9:10am to 3pm and the UV Index forecast to reach 6, which sits in the high range.

Across regional South Australia, conditions are a bit more varied. Early Wednesday starts cold in eastern districts, with patchy frost possible before temperatures rise well above average, especially in the west. A trough moving across the state’s far west is expected to trigger isolated showers and possible thunderstorms in the far southwest and the far northeast corner on Wednesday, before that unsettled pocket drifts closer to southern coastal areas on Thursday and Friday.

The broader statewide outlook remains warmer than average through to Saturday, with only light rainfall expected for most districts. Southern coasts may see the odd isolated shower, while the far southwest has the best chance of seeing thunderstorm activity. Rainfall totals are expected to stay low in most places, generally less than 2 mm across western parts and southern coasts, although local falls of 2 to 10 mm are possible in the far southwest, Kangaroo Island and the southern coasts of the Lower South East. For those on the water, Adelaide’s metropolitan waters look relatively calm through the period, with seas below 1 metre and only a freshening southeasterly on Saturday.

Happy Wednesday!
