Check the live forecast above before heading out in Wynnum today, as the bay breeze can shift conditions quickly along this stretch of Moreton Bay coastline.

What is the weather typically like in Wynnum?
Wynnum, a coastal suburb of Brisbane, sits on the shores of Moreton Bay, which means its weather is shaped by sea breezes and the bay’s moderating effect. Summers are warm and humid, with afternoon storms common, while winters are mild and dry. The bay keeps overnight temperatures a touch warmer than inland suburbs, and the wind off the water can make summer afternoons feel fresher than deeper in the city.
How does the bay influence Wynnum’s forecast?
The live forecast above reflects the local effect of Moreton Bay, which can create its own microclimate. North-easterly sea breezes often arrive by midday, dropping temperatures a few degrees compared to inland Brisbane, but they also push in humidity. For the most reliable outlook, check the bom weather wynnum radar for 7 days, as the bay can trigger isolated showers that don’t appear on broader models.
