Adelaide is set for a fairly calm start to the week, with cool autumn cloud lingering today before sunnier conditions and then a wetter change arrive later in the week. For locals, that means a run of mild days through the first half of the week, followed by increasing shower chances from Wednesday and a noticeably more unsettled end to the seven-day outlook.
Today in Adelaide will stay cloudy, with just a slight chance of a passing shower and a top of 19 degrees. Light winds should keep things fairly settled across the city and suburbs, with similar temperatures at Elizabeth, Glenelg and Noarlunga, while Mount Barker stays a little cooler at 17 degrees. Monday looks like the pick of the early week stretch, with mostly sunny skies, light winds and a cooler start of 10 degrees before reaching 21 degrees in the city.
By Tuesday, cloud will begin to build again across Adelaide, and there’s also the chance of morning fog around the hills and southern suburbs. Temperatures will climb a little further, with a minimum of 11 and a top of 23 degrees, before the pattern starts to shift on Wednesday. That’s when showers become more likely, especially later in the day and into the evening, as easterly winds pick up to around 15 to 20 km/h. Adelaide is forecast to reach 23 degrees again, with a medium chance of light rainfall.
The second half of the week keeps that more changeable feel in place. Thursday is expected to bring partly cloudy skies and a medium chance of showers, most likely during the morning, with northeasterly winds and temperatures holding steady between 14 and 23 degrees. Friday looks wetter, with a high chance of showers and possible rainfall of 1 to 15 mm. Northeasterly winds are expected to turn northerly during the day, while the temperature stays mild, ranging from 15 to 23 degrees.
Saturday rounds out the forecast with more showers likely and a slightly cooler top of 22 degrees. Light winds will return, but the city should still be prepared for a damp end to the week. Overall, Adelaide’s seven-day outlook is a classic mid-May mix: a grey and quiet start, a bright spell early in the week, then a run into cloudier, wetter weather by the weekend.
Across South Australia, conditions remain mostly dry at first under the influence of a strong high pressure system pushing slowly east. For the rest of Sunday, only isolated light showers are expected about the southern agricultural area and near far western coasts, with some morning fog possible about the ranges. Monday stays mostly dry across the state, although isolated showers may develop in the far north during the afternoon. By Tuesday, the broader pattern becomes more active, with isolated showers and possible thunderstorms across the far north, extending south into central districts during the day. On Wednesday, showers are expected east of around Coober Pedy, while southern parts of the state trend slightly warmer than average. Rainfall totals are generally expected to stay low across agricultural areas, though the North East Pastoral district could see 5 to 10 mm, with isolated falls up to 20 mm.
For coastal waters around Adelaide, marine conditions remain relatively calm through midweek, with seas and swell below 0.5 metres and generally light east to southeasterly winds. That should make for manageable conditions on local waters, although boaties should still keep an eye on daily updates as winds shift through the week.
