Adelaide is bracing for unpredictable weather patterns as a front moves through the region, according to the Bureau of Meteorology. On Thursday, March 20, 2025, the maximum temperature is expected to reach 28 degrees Celsius with showers likely and the possibility of thunderstorms in the morning and afternoon. Residents will experience a shift in winds from northerly to southwesterly.
Friday, March 21, brings a welcomed clearing trend with temperatures starting at a minimum of 17 degrees and peaking at 27 degrees. The good news is that the chance of rain is minimal, suggesting a more pleasant day overall. As the weekend approaches, the forecast improves significantly—Saturday is set to deliver full sunshine with temperatures ranging between 13 and 27 degrees while Sunday is likely to be slightly warmer, ranging from 14 to 29 degrees.
Looking further ahead, Monday, March 24, is expected to maintain the sunny streak with a minimum of 16 degrees and a maximum of 29 degrees. Tuesday, March 25, will continue this trend with similar temperatures, starting from a minimum of 15 degrees and reaching up to 30 degrees. However, as the week winds down, Wednesday, March 26, will introduce some cloud cover with temperatures dipping slightly to a minimum of 16 degrees and a maximum of 26 degrees.
The changing weather patterns are influenced by a high-pressure system moving in from the Tasman Sea, which is generating a northerly airstream. The current trough passing through the region, along with a cold front, is set to clip the southeastern parts of South Australia. By the end of the week, a weak ridge of high pressure is anticipated to provide more settled conditions.
On Thursday, isolated showers and potential thunderstorms were forecast across the western and pastoral districts, which will gradually extend across other areas as the day progresses. Following the passage of the front, winds were predicted to shift from northeast to northwesterly, finally settling to a cooler south to southeasterly breeze.
While light morning showers are expected on Friday near windward coasts and ranges, isolated showers are predicted to persist in the pastoral regions, alongside possible thunderstorms in the northern parts of the state. Interestingly, temperature variations indicate that the south could experience below-average temperatures, while the north remains warmer.
As for the weekend outlook, residents can expect isolated showers and thunderstorms in the northern pastoral districts while the southern regions are likely to remain dry. Winds will shift to a southeast to easterly direction and could become more intense near coastal locations.
By the end of Sunday, March 23, cumulative rainfall totals are expected to remain low, with most areas receiving less than 5 mm of rain. However, agricultural regions might see totals between 2 to 10 mm. Furthermore, areas impacted by thunderstorms in the northwest could receive as much as 40 mm of rain.
Looking forward to the early part of next week, isolated showers and possible thunderstorms are expected in the north, while the majority of the state will likely remain dry. Temperatures across the state will be observed at average to above-average levels, but a noticeable drop to below-average temperatures in the southeast is expected by Wednesday.
In summary, Adelaide’s weather forecast for the upcoming week shows a mix of conditions with initial showers giving way to sunny skies over the weekend. The temperatures will fluctuate with a promising trend towards warmer days as the week progresses.
