Sun-Smart Planning Essential as Extreme UV and Passing Showers Hit Brisbane

Tuesday Forecast Overview

Brisbane residents can expect a standard sub-tropical mix for Tuesday, February 17, 2026. The day is characterized by high humidity, manageable temperatures, and shifting cloud cover. The mercury is set to climb to a pleasant maximum of 29°C, following a mild overnight low of 20°C. While the conditions are ideal for outdoor activity, a high UV rating and a slight chance of precipitation mean locals should be prepared for changing conditions throughout the day.

Morning and Afternoon Predictions

The morning is expected to start with partly cloudy skies and a 20% chance of isolated showers. Early risers might encounter brief, passing dampness before the clouds begin to break up mid-morning. As the day progresses into the afternoon, the city will likely see a transition toward 'breaks of sun' as the cloud cover becomes more sporadic. The moisture in the air will remain high, maintaining that familiar Brisbane summer humidity.

• Morning (5:00 am – 12:00 pm): Partly cloudy with a slight chance of a shower. Temperatures rising from 20°C to 26°C.
• Afternoon (12:00 pm – 5:00 pm): A mix of sun and clouds with the day's peak of 29°C reached around 2:00 pm. Shower risk remains low but present.
• Evening (5:00 pm – 10:00 pm): Skies will begin to clear further as the sun sets at approximately 6:30 pm. Temperatures will gradually dip back toward the low 20s.

Wind and Rain Warnings

While no major weather warnings or severe storm alerts have been issued for the region today, the Bureau of Meteorology has noted a specific wind pattern. Light winds in the early hours will strengthen into an easterly to south-easterly breeze, reaching speeds between 15 and 20 km/h by the middle of the day. These coastal breezes will provide some welcome relief from the heat before becoming light and variable again during the evening. Total rainfall is expected to be negligible, with most areas likely to remain dry despite the 20% precipitation probability.

Extreme UV Alert

The most critical notice for Tuesday is the Extreme UV Index. Experts predict the UV levels will reach a rating of 12, which is considered extreme. Sun protection is highly recommended between the hours of 8:00 am and 3:50 pm. During this window, skin damage can occur very quickly. Residents are encouraged to use the five S's of sun safety: slip on a shirt, slop on sunscreen, slap on a hat, seek shade, and slide on sunglasses. Despite the cloud cover, UV rays can still penetrate and cause significant burn risk.

Fire and Coastal Outlook

For those heading to the water or the hinterland, there is currently no fire danger rating in effect for the Brisbane area. Coastal conditions remain steady with a sea temperature of roughly 26°C, making it a popular day for a dip, provided sun safety is maintained. Overall, it is a day to carry an umbrella just in case, but definitely don't leave home without your hat and sunscreen.
