Sun, Southerlies, and Scattered Showers: What to Expect in Wollongong Today

A Dynamic Forecast for the Illawarra

Wollongong residents should prepare for a transitional weather day this Thursday, 12 March 2026. While the morning may offer glimpses of sunshine, a southerly change is expected to bring increased cloud cover and scattered showers by the middle of the day. As your lead editor at wollongong.news, I have reviewed the latest meteorological data to ensure you are ready for the shifts in today's conditions.

Morning: A Bright but Humid Start

The day is beginning with relatively mild and clear conditions across the city and surrounding suburbs. Early morning temperatures have hovered around 19°C, providing a pleasant window for outdoor exercise or the morning commute. However, humidity levels are currently sitting near 70%, which may make the air feel slightly heavy as the morning progresses. By 10:00 AM, the temperature is expected to climb toward 23°C. Residents will notice clouds beginning to gather over the escarpment, signaling the arrival of a more unstable air mass moving up the coast.

Afternoon: Peak Heat and Approaching Rain

The mercury is predicted to reach a daytime high of 25°C by early afternoon. However, the window for sunshine will narrow significantly after midday. There is a 70% chance of rain today, with the highest probability of showers occurring between 1:00 PM and 4:00 PM. Total rainfall is estimated to fall between 1mm and 5mm, characterized mostly by scattered midday showers rather than a continuous downpour. Strengthening southerly winds will be a defining feature of the afternoon, averaging 24 km/h with gusts potentially reaching up to 35 km/h. These breezes will bring a noticeable cool-down, making the late afternoon feel significantly fresher than the humid morning hours.

Evening: Mild Conditions and Lingering Drizzle

As we head into the evening, conditions will stabilize, though the sky is likely to remain mostly cloudy. Temperatures will gradually decline to a low of approximately 21°C. While the most active shower activity should conclude by sunset, there remains a lingering 20% to 40% chance of light drizzle or patchy rain late into the night. For those heading out for dinner in the CBD, a light jacket and a compact umbrella are highly recommended to navigate any stray moisture.

Current Warnings and Statistics

At this stage, there are no active severe weather or wind warnings issued for the Wollongong area. Despite the gusty southerly winds, conditions remain well within the safety margins for standard daily activities. However, motorists are reminded to exercise caution on the roads, as the initial rainfall following a dry morning can lead to slippery surfaces, particularly on the twists and turns of Mt Ousley.
