The Lowdown
G'day, I'm Rusty.
Alright, let's have a look at what's on the cards for Bunbury Bay. We've got a bit of a mixed bag here, but there's some real potential if you pick your moments. The water temp is sitting right about where you'd expect for this time of year, nothing unusual.
The first decent window opens up on Friday, the 21st of August. Friday morning is looking like a standout. We've got a solid 6ft swell rolling in from the WSW, with a long 15-second period – that's proper groundswell energy. The wind is light and glassy from the east, so the surface will be clean as a whistle. The combined energy is a massive 1620, which is really pumping. This is excellent surf, but with that size and power, it's one for the experienced crew only.
The action drops off a bit over the weekend. Saturday morning offers a smaller 5ft swell from the same direction, but the wind is cross-shore, so it'll be a bit crinkly. Sunday is similar, with a 4ft to 5ft swell, and while the wind is cleaner, the energy is weaker.
Monday the 24th of August morning is another one to circle. The swell is back up to 6ft, WSW, with a 14-second period, and the wind is glassy again from the NNE. The energy is a strong 1223, and it's expected to be very good surf. Again, best for those with some experience.
We hit a bit of a lull from Tuesday the 25th through to Thursday the 27th of August. The wind turns onshore and gets messy, and the swell quality drops right off. The combined energy dips into the hundreds, with poor conditions.
Now, here's where it gets interesting and a bit wild. Wednesday the 26th of August sees a massive pulse of energy. A 10ft swell from the west, with a very long 19-second period, hits in the morning. The combined energy is a staggering 7425! The wind is clean and cross-offshore, but the forecast says it's just too big for Bunbury Bay. This is strictly for experts only, and even then, it'll be a handful. The same goes for the afternoon and into Thursday the 27th, with 8ft to 8ft swells and a lot of energy.
After that, the surf gets small and messy again from the 28th of August right through to the 2nd of September. There's a lot of onshore wind and poor conditions, with a few days of onshore wind and choppy seas. The energy drops right down to the low hundreds.
But hold on, because we've got a long-range highlight. On the morning of Thursday the 3rd of September, the stars align again. We're looking at a 8ft swell from the west, with a 17-second period. The wind is glassy from the SSW. The combined energy is a massive 4066. This is another excellent surf session for experienced surfers, but it's a long way out, so keep an eye on the charts.
And then on Saturday the 5th of September, the morning looks promising again. A 8ft swell from the WSW, with a long 18-second period, and glassy conditions from the NW. The energy is 3650. This is a promising one for the long-range.
So, to wrap it up, the pick of the bunch is Friday morning, the 21st of August, and Monday morning, the 24th of August. For the long-range, keep an eye on Thursday the 3rd of September and Saturday the 5th of September. The swell is big and powerful, so this is not a beginner's playground.
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.
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.
