Today’s high on Great Keppel Island is around the figure shown in the live forecast above, with a low in the upper teens to low twenties. The island experiences a subtropical climate, meaning mild winters and warm, humid summers, with most rainfall falling from December to March.
What is the typical weather pattern for Great Keppel Island?
The island sits off the central Queensland coast, so its weather closely mirrors that of the nearby mainland centres. Summer (December–February) brings average highs of 29–31°C and frequent showers or thunderstorms, often driven by the monsoon trough or tropical lows. Winter (June–August) is drier and cooler, with highs around 21–23°C and overnight lows of 12–15°C. The sea breeze moderates temperatures year-round, making the island slightly more comfortable than inland areas like Rockhampton.
What is the best time to visit for fine weather?
For reliable sunshine and low humidity, the months from May to October are ideal. Great Keppel Island weather in July and August typically offers clear skies, light winds, and average highs of 22°C – perfect for outdoor activities. Great Keppel Island weather in September sees a gradual warming, with highs around 25°C and still minimal rain. The live forecast above will give you the current conditions, but checking BOM Great Keppel Island for the latest marine and coastal warnings is also wise.
Does the island get cyclones?
Yes, the tropical cyclone season runs from November to April. Great Keppel Island is at low to moderate risk, but cyclones crossing the coast near Yeppoon weather can bring destructive winds and heavy rain. Always monitor BOM warnings if visiting in summer.
How do I get weather updates while on the island?
The BOM website and app provide the most reliable data. You can also check Rockhampton weather as a proxy since it’s the nearest major city. The Keppel Island ferry services often have live conditions posted before departure.
Is the water warm enough for swimming in winter?
Sea surface temperatures in winter average 20–22°C, which feels cool but is refreshing. Summer water temps reach 27–29°C. For longer stays, book Great Keppel Island accommodation that offers or advises on suitable swimming gear.
