Adelaide is facing its biggest rainfall of the year so far after a drier start to 2026.
The Bureau of Meteorology has forecast up to 20mm of rain today for the city, followed by 15mm tomorrow, and smaller falls in the following days.
Some forecast models suggest up to 40mm could fall in total.

It's a welcome change for the South Australia capital, which has been notably dry for months.
Weatherzone catalogued that the first four months of 2026 were wetter than usual across most parts of South Australia – except for Adelaide and its surrounding areas.
That pattern also applies to the past four years, which saw above-average rain in the north of the state, and lower than average falls to the south and south-east.

"Adelaide started 2026 with a completely dry January, and that dry city gauge was no localised anomaly," Weatherzone reported.
"Even up on Mount Lofty in the Adelaide Hills – where the annual average rainfall of 973mm is 81 per cent more than the city's 537.6mm – just 1.8mm of rain fell in January."
The current wet spell, with rain driving down from the state's north, is forecast to last until Wednesday next week.
"It's also a slow-moving system, with the trough and front sliding southeast rather than pushing east due to the blocking high over the Tasman," Weatherzone meteorologist Jess Miskelly said.
"This means the system will be in the vicinity longer, hence able to cause more rain."
