The Lowdown
Alright folks, Rusty here. Let’s get into it. We’ve got a solid 16-day window ahead for Bunbury Bay, but it’s a bit of a rocky start with some clean-up days to get through. The pattern is a slow burn, with a few standout sessions that’ll have you calling in sick.
The first few days, from the 9th through the 12th, are a write-off. The swell is there, with a long-period groundswell of 15 to 18 seconds pushing in from the West, pushing 4ft to 6ft, but the wind is just a mess. Cross-off and cross-on breezes, moderate energy levels (around 1528 to 1416 in the water) keep things choppy and marginal. You’re better off waiting for the tide to do its thing and not bothering.
Now, hold onto your board. The 14th and 15th of September are where it’s at. Monday morning the 14th, we’ve got clean conditions. The wind goes light and cross-off from the NE, at just 3 mph, and the swell is pumping at 6ft from the WSW. That’s a solid 14-second period groundswell, delivering a nice punch of energy (1344). The water is about average for this time of year, nothing crazy. For the experienced crew, this is a proper session. Tuesday the 15th is another cracker – morning glass-off with a 9 mph S cross-off wind, keeping the 7ft swell clean and powerful (1811). That’s your best bet for the first week. The break is fairly consistent, though it’s a beginner-friendly spot, so watch for a few folks out there.
After that, things drop off. The 16th has a clean morning with 4ft from the WSW, but it’s not the standout. Then from the 17th right through the 20th, it’s a solid block of poor surf. The wind swings onshore and gets strong, with rain showers and lumpy conditions. The swell is all over the place, but the quality is garbage. It’s a gap of several days of nothing.
But hold on, because the 22nd of September is a real gem. Tuesday morning, the wind is glassy – dead calm, 3 mph from the NNW. The swell is a solid 8ft from the WSW with a 16-second period (3318). That’s a lot of energy. This is only for the experts – it’s big, powerful, and will be a handful. For the rest of us, it’s a great show. The 23rd morning cleans up with a 5ft WSW swell and a light cross-off breeze, making it a good option for the more moderate crowd.
So, the standout is clear: Monday the 14th and Tuesday the 15th for the experienced, and the big glassy morning on the 22nd for the brave. The rest is a waiting game.
Rusty, signing off.

Information about the Bunbury Bay Surf forecast
The above surf forecast table for Bunbury Bay provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Bunbury Bay can be found by selecting the local surf guide option on the grey menu. Our Bunbury Bay surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period.

Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Bunbury Bay may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
