Passing Showers to Cool St. Patrick’s Day Celebrations

A Gray and Damp Start for Melbourne

Melburnians should keep an umbrella close at hand this Tuesday, 17 March 2026. As the city celebrates St. Patrick’s Day, the weather is expected to remain largely overcast with intermittent light rain showers throughout the day. Residents waking up early can expect a cool and humid start, with temperatures beginning at a minimum of 13°C. Humidity levels are particularly high this morning, peaking at approximately 84%, which may lead to patches of mist or low-lying cloud across the suburbs during the morning commute.

Afternoon Conditions and Temperature Peaks

By the afternoon, the temperature is forecast to reach a modest maximum of 19°C to 20°C. While these temperatures are comfortable for outdoor activities, the risk of rain remains steady. Meteorological data suggests a 35% to 67% chance of precipitation, with total rainfall amounts estimated at around 5mm. The showers are expected to be passing rather than persistent, meaning there will likely be breaks in the cloud cover, though a clear blue sky is unlikely before sunset. For those heading out to local festivities, the UV index is rated at a moderate level of 3, so sun protection is still recommended during the brighter intervals.

Evening Forecast and Wind Activity

As we head into the evening, the showers are predicted to taper off. Conditions will remain cloudy, though the chance of rain drops significantly to just 5% after dark. Temperatures will begin to dip back toward the overnight low of 14°C. Winds throughout the day are expected to be relatively gentle, primarily originating from the south at speeds of 10 to 15 km/h, with occasional gusts reaching up to 23 km/h. These light breezes may add a slight chill to the air, particularly in coastal areas near Port Phillip Bay.

Summary of Today's Conditions

• Temperature Range: Low of 13°C, High of 20°C.
