Live forecasts update automatically; written guidance last reviewed 23 June 2026 by the Australia Watch Weather Desk. Data from the Bureau of Meteorology (BOM) and other national met services via Open-Meteo.
Check the live forecast above before heading out, as Mt Cotton’s subtropical climate means conditions can shift quickly from a warm morning to an afternoon storm. This page explains what drives the local weather and how to stay prepared.
What makes Mt Cotton’s weather different?
Mt Cotton sits in the Scenic Rim region of south-east Queensland, about 30 kilometres south of Brisbane’s CBD. Its elevated terrain and proximity to Moreton Bay create a localised microclimate: mornings often start with low cloud or fog, then clear to a warm day, before afternoon sea breezes or summer storms roll in. The Bureau of Meteorology’s Brisbane weather forecasts are a good starting point, but the hilltop location can be a few degrees cooler and windier than the city.
What should you expect season by season?
Summer (December to February) brings the highest rainfall and humidity, with frequent afternoon thunderstorms. Winter (June to August) is mild and dry, with crisp mornings and clear skies. Spring and autumn offer the most stable conditions, though sudden changes are still possible. For real-time tracking, the bom radar brisbane loop is the most reliable tool to see if a storm is heading your way.
Where can I find the mt cotton weather bom forecast?
