Macleay Island Weather Forecast & Warnings (4184)

Southern Moreton Bay Climate

Macleay Island sits within a humid subtropical climate zone, heavily influenced by its position in the sheltered waters of Southern Moreton Bay. Being an island location, it often experiences slightly moderated temperatures compared to the inland suburbs of Brisbane, with cooling sea breezes providing relief during the height of the Queensland summer. The surrounding water mass acts as a thermal regulator, keeping overnight minimums often higher than those recorded at the mainland weather stations.

Seasonal Weather Patterns

The region is characterised by distinct seasonal shifts. Summer months typically bring higher humidity and the risk of afternoon thunderstorms, which can be intense and fast-moving. Historically, the broader South East Queensland coastline is susceptible to the remnants of tropical cyclones moving south, which can result in significant rainfall events and increased swell. During the winter months, the weather is generally mild and dry, dominated by high-pressure systems that bring clear skies and light winds, making it the peak time for local boating and fishing.

Prevailing Winds and Marine Risks

Wind conditions are a critical factor for Macleay Island due to the reliance on ferry and barge transport. Prevailing south-easterly trade winds are common for much of the year. However, the area can be impacted by East Coast Lows, which bring gale-force winds and heavy rain to the Queensland coast. These systems can lead to coastal erosion and hazardous conditions within the bay. Residents should also remain aware of bushfire risks during dry springs when westerly winds bring hot, dry air from the interior of the continent toward the coast.
