The Lowdown
Alright folks, Rusty here with a look at the only game in town for the next couple of weeks. We've got one break to work with, so let's see what it's offering.
The outlook for Bunbury Bay is a bit of a mixed bag. We're looking at a solid run of swell, but the conditions are going to be the real story. The water temp is about average for this time of year, so no surprises there.
For the first few days, it's a write-off. Monday and Tuesday are blown out with strong, messy winds and a big, unruly 10ft swell from the WSW. The wave energy is massive – we're talking readings in the thousands – but it's all for nothing with that wind. Kite surfers might be having a field day, but for a paddle surfer, it's a hard pass.
Things start to look up on Thursday morning, August 13th. The swell drops to a more manageable 6ft from the WSW, and more importantly, it goes glassy. That's a huge positive. The wave energy is still moderate at 1596, and with a 16-second period, this is a proper groundswell. It’ll have some serious push but might be a bit straight for the beach break. This is the standout for the first week – clean conditions and a solid swell for experienced surfers.
Friday morning, August 14th is another good shout. A 6ft WSW swell with clean conditions and light offshore winds. It's a similar story to Thursday, with that long-period groundswell offering good shape but perhaps a bit too much power for the beach break setup.
After that, the swell backs off a bit and the winds get messy again through the weekend, with only marginal surf on offer. Sunday afternoon, August 16th sees a glassy 6ft W swell roll in, which is worth a look, but it’s not as strong as the Thursday morning session.
Then, we get a massive pulse of swell around Monday, August 17th. We're looking at a 10ft W swell with an 18-second period and wave energy over 5000. This is serious stuff. The winds are light, but the size makes this an expert-only zone. It's a proper bomb, but only for those with the skills to handle it.
The following week is mostly a bust. The wind stays onshore and messy, keeping the quality poor right through to Saturday, August 22nd, when the wind swings offshore again, giving us a clean 7ft WSW swell. It's worth a mention, but it's a long way out, so don't get your hopes up too high. The very end of the period, Sunday morning, August 23rd, looks glassy with a 5ft W swell, another promising but distant prospect.
So, the best on offer is Thursday morning, August 13th for the clean conditions and solid groundswell, with Friday morning, August 14th as a close second. The big stuff on the 17th is for experts only. The rest of the time, it's a waiting game.
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.
