Macleay Island Weather Forecast & Warnings (4184)

Southern Moreton Bay Climate Patterns

Macleay Island is situated within the subtropical latitude band of South East Queensland. Its position in the protected waters of Moreton Bay means the local climate is heavily moderated by the surrounding sea. This maritime effect typically results in slightly cooler summer maximums and milder winter minimums compared to inland regions like Ipswich or Logan. Residents and visitors should monitor the prevailing south-easterly trade winds, which are a dominant feature of the coastal environment for much of the year.

Seasonal Weather Drivers

During the summer months, the region is prone to high humidity and convective thunderstorm activity. These storms often develop over the Great Dividing Range and move towards the coast, bringing heavy rainfall and occasional lightning. While Macleay Island is south of the primary tropical cyclone strike zone, the remnants of ex-tropical cyclones can occasionally move down the coast, resulting in significant rainfall events and increased swell in the bay. In the cooler months, the weather is governed by high-pressure systems moving across the Australian continent, providing clear skies and light winds.

Severe Weather and Marine Conditions

Given its island geography, wind speed and direction are critical factors for those relying on the ferry and barge services. Strong wind warnings are common when vigorous troughs move through the area. During late autumn and winter, East Coast Lows can occasionally develop off the Queensland coast, bringing sustained gale-force winds and heavy rain. Fire safety is also a consideration during the dry spring months when westerly winds can bring low humidity and increased risk to timbered areas of the island.
