What’s Happening?
Maritime Safety Queensland and the Bureau of Meteorology have joined forces for a boating safety message this August.
They are urging boaties to use current marine forecasts before making decisions on the water.
Known as Ekka Winds, strong westerlies can affect south-east Queensland waterways when cold fronts reach the state. These winds can create steep, choppy seas and leave smaller vessels facing a harder return.
Why It Matters
Conditions can appear calm near homes, ramps or shorelines, while offshore waters are already rougher. Winds may also strengthen after early morning, changing the trip home later in the day.
That difference matters because a manageable outward trip can become difficult or dangerous on the return. Planning for the whole outing reduces the risk of being caught by worsening weather.
Local Impact
Across the affected south-east waterways, westerly winds can create a short, steep chop. Moreton Bay can be particularly difficult, while open waters often experience stronger winds than nearby land.
Reduced friction over water allows winds to strengthen, while seas can build throughout the day. Local boaties should not assume conditions at the ramp reflect what is happening farther offshore.
By The Numbers
- Three key boating areas may feel the effects most clearly, including Moreton Bay, Gold Coast and Sunshine Coast waters.
- Both legs of a trip matter because conditions can differ between the outward run and the return.
- Every person aboard should wear a lifejacket, while all safety equipment should remain current and working.

Before launching, boaties should review the Bureau’s coastal waters forecast and marine warnings. They should continue checking updates throughout the trip, rather than relying on one observation.
Maritime Safety Queensland General Manager Kell Dillon said the partnership would support safer decisions on the water.
“Maritime Safety Queensland helps boaties make safe decisions before they launch, while the Bureau provides the forecasts they need to plan their trip,” Mr Dillon said. “Conditions may look fine at the ramp, but that does not always reflect what is happening offshore or later in the day. Winds can strengthen after early morning, making the return journey very different from the trip out. Strong westerly winds can produce a short, steep chop, particularly on Moreton Bay, making the journey home difficult and dangerous. Our message is simple: check the forecast, plan the whole trip and, if conditions are unfavourable, stay ashore.”
Zoom Out
Ekka Winds develop when cold fronts crossing southern Australia reach Queensland. These systems are more frequent around August and can bring bursts of stronger westerlies.
Bureau of Meteorology senior meteorologist Rosa Hoff said forecasts and warnings provide vital information about changing wind and marine conditions.
“At this time of year, cold fronts crossing southern Australia can reach Queensland, bringing bursts of strong westerly winds across the south-east,” Ms Hoff said. “Conditions close to shore can be different to those in open water. Winds are often stronger over the water because there is less friction than over land, while seas can build during the day and swell conditions can change.”
What To Look For Next?
Cold fronts may keep producing bursts of strong westerlies across south-east Queensland during August.
Boaties should check the Bureau website or app before launch, then keep monitoring forecasts and warnings. If conditions are unfavourable, staying ashore remains the safest choice.
