Brisbane is starting Wednesday with a small chance of morning showers before the day turns hot and mostly sunny, with the mercury set to push into the low 30s. While the city itself isn’t under a marine wind warning, Queensland waters farther north are on alert, and the broader pattern is a reminder that late-summer conditions can shift quickly across the state.
Brisbane forecast for today
The latest city outlook points to a warm day overall, with only a limited window for light morning showers before clearer skies build in the afternoon. The key numbers for Brisbane today are:
- Minimum: 21°C
- Maximum: 31°C
- Chance of any rain: 30%
- Possible rainfall: 0 to 1 mm
That combination suggests a day where roads may briefly be damp early, but widespread wet weather is unlikely. Any showers that do develop are expected to be short-lived rather than persistent, and the afternoon is forecast to lean mostly sunny.
Winds and how the day may feel
Light winds are expected early, then turning easterly at around 15 to 20 km/h through the middle of the day before easing again later. With humidity still lingering in early March, Brisbane’s 31°C peak can feel warmer than the number suggests, especially in built-up areas and during the early afternoon.
If you’re heading out, the most noticeable shift may be the classic southeast Queensland rhythm: slightly unsettled in the morning, then brighter and hotter as the day goes on.
UV alert: extreme levels
Even with morning cloud around, UV levels are expected to be very high. The UV Index is predicted to reach 12 (Extreme), with sun protection recommended from 8:10 am to 3:50 pm. This is the kind of day where sunburn can happen quickly, even if the sky looks forgiving early.
Queensland marine wind warning
A separate marine update issued for Queensland highlights stronger coastal conditions to the north, relevant to boating and offshore activity. The warning states:
Marine Wind Warning – Queensland
Issued at 3:00 am EST on Wednesday 4 March 2026, for the period until midnight EST Thursday 5 March 2026.
- Strong Wind Warning: Townsville Coast and Mackay Coast
- Cancellation: Cairns Coast
For Brisbane residents, this is mostly background context rather than an immediate local threat. Still, it matters for anyone travelling, working along the coast, or planning marine activity beyond the southeast.

What to expect through the evening
As the easterly breeze eases later, Brisbane should settle into a calmer evening. The main storyline is less about rainfall totals and more about heat, humidity, and exposure during the middle of the day. If showers appear early, they’re expected to be light and brief, with the afternoon carrying the better odds for outdoor plans.
Brisbane today in one line
Possible morning shower, then a hot 31°C afternoon with extreme UV—and marine winds running stronger along parts of the Queensland coast to the north.
