Sky Watch: Showers and Extreme UV Levels to Kick Off the Week in Wollongong

A Humid Start to the Autumn Season

As Wollongong transitions from the peak of summer into the first days of autumn, Monday, 2 March 2026, brings a complex mix of conditions to the Illawarra. Residents can expect a predominantly overcast day characterized by high humidity and the persistent threat of passing showers. While the mercury will remain within a comfortable range, the combination of moisture and solar intensity makes for a day that requires both an umbrella and high-grade sun protection.

Morning: Damp Conditions and Mild Temperatures

Commuters heading out early this morning will be met with a mild start, with temperatures sitting at a steady 21°C. The sky is expected to remain overcast, with a 60% chance of rain throughout the morning hours. Rainfall is predicted to be relatively light, with total accumulations for the day estimated between 0 and 5 mm. Winds will be gentle, primarily coming from the southwest at speeds between 5 and 15 km/h, though the high humidity—hovering near 80%—will make the air feel significantly heavier than the temperature suggests.

• Temperature: 21°C
• Conditions: Overcast with a high probability of patchy rain.
• Wind: Light southwesterly breezes.

Afternoon: Peak Warmth and Extreme UV Alert

By the early afternoon, the temperature is forecast to reach a maximum of 26°C. Despite the cloud cover and the high likelihood of intermittent showers, the Bureau of Meteorology has issued an Extreme UV Alert. The UV Index is expected to hit a peak of 11 today. Health authorities recommend seeking shade and wearing sun-protective clothing, especially between the hours of 9:20 am and 4:50 pm when the solar radiation is most intense.

For those considering a visit to the coast, the average sea temperature remains a welcoming 23.1°C. However, with the 60% chance of showers continuing into the afternoon, beachgoers should be prepared for sudden changes in weather. The atmosphere will remain quite muggy as moisture continues to stream in from the coast.

Evening: A Sticky Night Ahead

As the sun sets around 7:32 pm, temperatures will begin a slow descent back toward 20°C. The humidity is expected to climb even higher during the evening hours, potentially reaching 85-88%. While no severe wind or flood warnings are in place, the persistent dampness and lack of strong winds may lead to a sticky night for the region. Passing showers remain possible into the late evening, though they are expected to be brief.
