The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the cards for our stretch of coast. The next 16 days start with a massive pulse of energy, but it's going to be a bit of a handful for most of us.
First up, Wednesday the 26th of August. We’ve got a serious swell rolling in, 10 ft from the west with a very long period of 19 seconds. The energy is huge, clocking in at 6688, but that’s the problem – it’s just too big for this break. The morning is glassy with a light NNW breeze of 3 mph, but unless you’re on a serious step-up and know what you’re doing, it’s a day to watch. The water is sitting at 62°, which is a bit colder than normal for this time of year. The afternoon stays big at 10 ft, but the wind swings to a cross-off SSE at 9 mph, keeping it clean. Still, same story – too much size for most.
The swell eases a touch on Thursday the 27th, dropping to 7 ft in the morning and 7 ft in the afternoon. The period is still lengthy at 16 and 14 seconds respectively. However, the wind is howling from the SSE at 19 mph in the morning and 16 mph in the afternoon, making for choppy, blown-out conditions. The energy is moderate at 2386 and 1591, but the quality just isn’t there. We get a brief window on Friday the 28th with a drop to 4 ft and clean offshore winds from the SE at 19 mph. The period is 13 seconds, and the energy is weak at 440. It’s small and clean, but barely worth a paddle. The afternoon is even smaller at 3 ft, though still clean.
Now, Saturday the 29th is where it starts getting interesting. The morning has 4 ft from the WSW with a very long period of 19 seconds and moderate energy at 949. The wind is off from the east at 16 mph, making it clean. It’s small but the quality is there. Then Saturday afternoon – this is the pick of the first week. Swell bumps up to 5 ft from the WSW with a very long period of 18 seconds (1447 energy). The wind goes light offshore from the ESE at 9 mph, giving us clean, lined-up waves. This is excellent for experienced surfers, though the long period might make it a bit straight at the beach, so look for a bank with a bit of shape.
We get a messy run from Sunday the 30th through to about Thursday the 3rd of September. Swell hangs between 4 ft and 7 ft, but the wind is all over the shop – onshore, cross-onshore, or just ugly. The energy drops to moderate levels (855 to 1850), but the quality is poor. Not worth the drive.
Saturday the 5th of September brings a nice little reset. The morning is magic: 5 ft from the WSW with a 13-second period, but it’s glassy – wind from the SSE at just 3 mph. The energy is moderate at 711. Clean, small, and perfect for a longboard or a fish. The best of the second week is Thursday the 10th of September. The morning has 8 ft from the west with a very long period of 18 seconds and strong energy at 4897. The wind is offshore from the east at 9 mph, giving us clean, powerful waves. This is for experienced surfers only, as it’s big and punchy, but the quality is excellent. The afternoon gets even bigger at 10 ft and 18 seconds (5320 energy), but again, that’s pushing into expert-only territory and the wind goes light and variable.
Overall, the standout windows are the afternoon of Saturday the 29th of August for clean, fun shoulder-high waves, and the morning of Thursday the 10th of September for a bigger, more powerful session for the crew with the skills. The rest is either too big, too windy, or too small. Keep an eye on the sky.
Rusty.

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.
