Cooler Southerly Change to Sweep Through the Illawarra This Thursday

Morning: A Fresh Start for Wollongong

Residents of Wollongong can expect a noticeable shift in the atmosphere early this Thursday, 29 January 2026. After a period of warmer conditions, a surge in coastal winds is forecast to move up the New South Wales coast, crossing the Illawarra region during the morning hours. This wind change will likely bring an increase in cloud cover and a welcome drop in temperature compared to the mid-week peak. Early morning commuters may encounter patchy light rain or isolated showers as the front pushes through, though rainfall totals are expected to remain low, likely under a millimetre.

Afternoon: Mild Temperatures and Cloudy Intervals

By the afternoon, the southerly influence will be well-established, keeping conditions significantly milder than previous days. Daytime temperatures are expected to reach a maximum of approximately 25°C, though some coastal areas may hover closer to 21°C depending on the timing and strength of the wind surge. Humidity levels will remain relatively high at around 84%, which may make the air feel slightly heavier despite the cooler breeze. While the sun will occasionally peek through the clouds, the afternoon will be characterized by a mix of overcast spells and a 25% chance of light, passing showers.

Evening: Clearing Conditions for a Mild Night

As we move into the evening, the chance of precipitation will taper off, leaving the region with clear to periodically cloudy skies. Nighttime temperatures are set to settle at a comfortable minimum of 18°C to 19°C. The brisk morning winds are expected to ease by nightfall, making for a pleasant and settled evening for those heading out in the CBD or along the coast.
