The Lowdown
Alright, let’s have a look. Bunbury Bay is going to be a tough nut to crack for a while. There’s some serious size coming, but this wave just can’t handle it when it gets that big. You’ll want to be careful.
The first big pulse rolls in early Wednesday, August 26. Glassy conditions, a clean 10-foot swell out of the west, but it’s got 19-second periods and a massive combined swell energy of (6759). That’s way too much for this spot for most folks – expert-only territory for sure. The water temp is 62°, which is a bit colder than normal for this time of year.
Thursday the 27th is still not great – clean surf but strong winds and 7-foot swell are making it messy and frustrating. Friday and Saturday morning the 29th will be small and poor.
Now, the real standout: Saturday afternoon, August 29. Still decent energy (1464) with a clean 5-foot west-southwest swell, but the wind will be a light offshore from the southeast at 6 mph. That’s the cleanest window in the whole run. This is the pick for experienced surfers at Bunbury Bay. Crowds show up sometimes, but for that session? Might be worth a look.
Sunday the 30th through Monday the 31st is marginal – light cross-onshore breezes and moderate westerly energy. Nothing too exciting. Tuesday morning, September 1, has a small but clean session with offshore east-northeast winds and a 6-foot westerly groundswell. Calm and clean – decent for more confident surfers.
After that, it’s a long stretch of poor to marginal conditions. Strong onshore winds ruin things from Wednesday the 2nd into the second week. There’s a chunky pulse on Saturday, September 5, with 8-foot swell, but the wind is howling onshore – blown-out and messy. Same on Sunday the 6th – near gale force northwest winds and onshore swell. Not surfable.
By Monday, September 7, it’s still raw with strong cross-shore winds and deteriorating conditions. The only light at the far end is Tuesday morning, September 8, with light east-southeast offshore wind and a small but clean 4-foot swell – not a big day, but worth a paddle if you’re keen. Then it trails off into small, crummy stuff.
Overall: if you can handle big, clean swell on Wednesday the 26th, that’s the standout for experts. For everyone else, circle Saturday the 29th afternoon – that’s the cleanest, most user-friendly day on offer.

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.
