Adelaide is set for a mostly calm and sunny run to start the week, before a cooler change brings showers and brisker conditions by midweek.
For Sunday, Adelaide can expect mostly sunny skies and a top of 17 degrees, with light winds keeping things fairly settled across the metro area. Monday looks much the same, with another mostly sunny day on the cards and temperatures lifting slightly to 18 degrees after a low of 9 overnight. Tuesday stays pleasant too, with partly cloudy skies and a top of 17 degrees, as the city holds onto the quieter weather before conditions turn.
The shift arrives on Wednesday, when showers are expected to move into Adelaide and bring the wettest day of the week. The Bureau of Meteorology is forecasting a very high chance of rain, with 1 to 5 mm possible and a cooler maximum of 15 degrees. Winds will pick up through the day, starting from the northwest to northeasterly before swinging west to southwesterly, which is likely to make the change feel noticeably colder across the city.
That cooler pattern lingers into Thursday, with a possible shower or two, especially in the morning, and a top of 14 degrees. Southwesterly winds of 15 to 20 km/h will keep things feeling fresh. By Friday, conditions begin to settle again, although Adelaide is likely to stay on the cool side. Partly cloudy skies and just a slight chance of a shower are forecast, with temperatures ranging from 5 degrees overnight to 14 during the day.
Saturday rounds out the week in a similar fashion, with partly cloudy conditions, a slight chance of a passing shower, and light winds becoming northwesterly during the day. The maximum is expected to stay at 14 degrees after a low of 6, making for a fairly typical mid-winter weekend in Adelaide.
Across South Australia, the broader picture is relatively quiet for the next couple of days thanks to a strong high pressure system over Victoria extending a ridge across the state. That means dry weather for most districts through Sunday, Monday and much of Tuesday, along with morning fog on and east of the ranges and the chance of frost in some inland areas early on Sunday. Maximum temperatures are sitting slightly above average through the first half of the week, especially away from the southern districts.
By Tuesday, a weak trough developing in the west will start to signal a change, ahead of a cold front pushing over southern districts during Wednesday. While most of the state will remain dry until then, western Kangaroo Island could see a late light shower on Tuesday. On Wednesday, isolated showers are forecast to extend into the agricultural districts during the morning before contracting mainly to coastal areas later in the day. Rainfall totals are expected to stay low, with less than 3 mm across most agricultural areas, although isolated falls of 2 to 5 mm are possible over western parts of Kangaroo Island and the Lower South East coast.
For those heading onto the water along Adelaide’s metropolitan coast, conditions look favourable through the start of the week. Winds remain light from the north to northeasterly on Sunday through Tuesday, with seas below 1 metre. Wednesday brings a more noticeable shift, with north to northwesterly winds turning southwesterly during the afternoon, seas building to around 1 metre, and a 90 per cent chance of showers.
