The Lowdown
Right off the bat, the ocean’s got a bit of a pulse around Bunbury Bay, but it’s gonna take a little patience to find the good windows. The water temp is sitting right about average for this time of year, which is nothing to write home about, but it’s not freezing your toes off either.
Saturday morning kicks things off with a solid 5ft WSW groundswell, and that 16-second period has some serious push behind it. The combined energy is reading a strong 1348, and with that light S cross-off breeze, it’s gonna be clean. This is one for the experienced crew – the swell is solid and the power is real. It’s not a day for beginners, that’s for sure. But if you’re comfortable in solid overhead waves, this is your session. The crowd might be around, but for waves like this, it’s worth it.
After that, things get messy. The wind swings around and picks up, and Sunday and Monday are looking chopped up and onshore. The swell drops and the quality goes with it. You’ll see some waves, but they’re gonna be a battle. Tuesday gets worse with fresh onshore winds and crap conditions.
Then, Wednesday throws a curveball. The swell jumps to 12ft, and the energy goes ballistic at 8185. That’s a big, powerful, angry ocean. The wind is cross-onshore and choppy in the morning, which is a mess. But Wednesday afternoon, the wind eases to a moderate cross-shore, and the call is that the swell is just too big for this break. If you’re a solid expert, maybe you look at it, but honestly, it looks like it might be more of a kite-surfing show than a paddle session. The power is immense, but it’s not your friend here.
Thursday is where the magic happens. The swell settles to a manageable 7ft, still from the W, with a 15-second period. The wind goes light and cross-off in the morning, and it’s clean. Excellent conditions for experienced surfers again, but with less juice than Wednesday. The energy is still strong at 2177, so there’s plenty of push. The afternoon stays clean with a gentle cross-off. This is your standout. The morning is the best of the two, with that light offshore breeze grooming it to perfection.
Friday calms down a lot, with the swell dropping to around 4-4ft. It’s clean, but small. There’s a few fun ones for the longboard or a groveler, but nothing to get too excited about.
The weekend and into next week becomes a real mixed bag. Saturday is small with tricky winds, Sunday gets blown out again. The following week, there are a few interesting windows. Monday afternoon the 31st looks glassy with a clean 6ft W swell, and Tuesday afternoon on the 1st of September also looks glassy with 6ft. Those look like fun, clean sessions, but not as big or powerful as the 27th.
The second week gets less predictable. The first week’s calls are solid, but by then, you’re just hoping. Early September looks like it might pull in a bit more W swell, but the winds are fickle. There are a couple of clean mornings, but it’s a gamble. Keep an eye on the charts, but the standout day to plan your week around is that Thursday, August 27th. That’s the one.

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. If you surf the same spot (Bunbury Bay) regularly then make a mental note of the wave energy from the surf forecast table each time you go. 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.
Bunbury Bay is 3 km (2 miles) from the city of Bunbury. If you plan a holiday in Perth South Coast, look for hotels and other accommodation in Bunbury. Bunbury has rooms for a wide range of budgets as well as car hire and transport links.
