Passing Showers and Tropical Humidity: Brisbane’s Tuesday Weather Breakdown

A Mixed Bag for the River City

Good morning, Brisbane. As we move further into the final week of March 2026, the weather across the South East is proving to be a classic late-summer blend of warmth and moisture. Residents waking up today, Tuesday, 24 March, can expect a day defined by high humidity and the persistent threat of passing showers. While we aren't looking at any major severe weather warnings, the conditions will require a bit of planning for those commuting to the CBD or planning outdoor activities.

Morning: A Humid and Cloud-Filled Start

The day begins with a relatively mild and muggy morning. Temperatures are starting at a low of 20°C, with humidity levels sitting high at approximately 64% to 85% in some coastal pockets. Early risers may notice periodic cloud cover moving in from the bay. While the early hours remain mostly dry, the Bureau of Meteorology indicates that clouds will continue to build throughout the morning. Light winds from the east-southeast at approximately 13 mph (21 km/h) will provide a slight breeze, but the high moisture content in the air will likely make it feel warmer than the thermometer suggests.

Afternoon: Peak Heat and Showers Likely

As we head into the afternoon, Brisbane will hit its expected maximum temperature of 30°C. With the tropical air mass sitting over the region, the 'feels like' temperature is predicted to hover around 31°C. This is when the chance of rainfall is at its highest. There is currently a 60% probability of showers across the metropolitan area, with rainfall totals estimated between 0 and 8 mm. These are expected to be passing showers rather than a consistent downpour, meaning you might see a quick burst of rain followed by intervals of sunshine. The UV index is currently rated as moderate (3), but given the patchy nature of the clouds, sun protection is still recommended for any extended periods spent outdoors.

Evening and Overnight: Clearing Skies

By the time the sun sets this evening, the chance of rain will diminish to around 15%. The sky is expected to clear significantly, leading to a mostly fine night. Temperatures will gradually drop back down to an overnight low of 20°C, providing some relief from the afternoon's humidity. Winds will remain light, shifting slightly as the evening progresses, ensuring a relatively still and quiet night for the suburbs.
