Keep the Brolly Handy: Showers and Humidity Set to Sweep Through the River City

A Damp and Sweltering End to the Work Week

Brisbane residents should prepare for a damp and humid end to the work week as Friday, March 13, 2026, brings a high likelihood of rain and sweltering temperatures. While the morning may start with brief windows of sunshine, the latest meteorological data suggests umbrellas will be a necessary accessory for anyone heading into the CBD or surrounding suburbs today.

Morning: A Muggy Start and Building Clouds

The day is set to begin with a minimum temperature of 22°C, but the high humidity levels will make it feel significantly warmer from the first light of dawn. Expect partly cloudy skies during the early morning commute, though this relatively clear weather will be short-lived. Forecasters indicate that showers are most likely to begin developing in the late morning. For those planning outdoor exercise or early coffee meetings, it is advisable to finish by 10:00 am to avoid the first of the day's precipitation.

Afternoon: Peak Heat and Showers Arrive

As we move into the afternoon, temperatures are expected to climb to a maximum of 32°C. The combination of high heat and moisture will create sticky, uncomfortable conditions across the metropolitan area. The chance of rainfall today sits at a significant 80%, with between 1 mm and 10 mm of total precipitation predicted. These showers are expected to be most persistent throughout the mid-to-late afternoon, with some models suggesting the potential for scattered thunderstorms to develop alongside the rain bands.

• Wind Conditions: Early light winds will shift in the middle of the day, becoming southeasterly at speeds of 15 to 25 km/h. This may provide a slight cooling effect, though it will do little to break the underlying humidity.
• UV Warning: Despite the cloud cover and the high probability of rain, the UV Index is forecast to reach 10, which is classified as "Very High." Sun protection is strongly recommended between 8:20 am and 3:30 pm.

Evening: Settling into a Sticky Night

As the sun sets around 6:07 pm, the heavier showers are expected to taper off into scattered sprinkles, though dense cloud cover will remain throughout the night. The evening will stay warm and humid, typical of Brisbane’s early autumn climate. While no major wind or severe weather warnings are currently active, drivers are urged to take care on the roads; the initial rainfall after a dry spell can lead to particularly slippery surfaces during the Friday evening rush hour. Overall, it is a day to stay hydrated, keep sun-safe during the clear spells, and ensure you have a plan for the afternoon rain.
