The Lowdown
Alright, listen up. Rusty here, looking at the next couple of weeks for Bunbury Bay.
First thing, the water’s a bit cooler than usual for this time of year, sitting at 61°. That’s a decent drop from the norm, so suit up.
This forecast is a straight-up fight with the wind. We’ve got a massive run of southwest groundswell, but the wind is just not cooperating for most of it. The first real chance to score doesn’t come until way late in the window.
The entire first week is a total bust. From Friday the 7th all the way through Thursday the 13th, it’s blown out, too big, or just plain messy. We’re looking at wave heights from 8ft up to a crazy 13ft, with a very long period of 15 to 17 seconds, but it’s hammered by strong onshore winds. The wave energy is massive – numbers like 3256 and even 9401 – but it’s all ugly. Sunday morning the 9th has a 10ft WSW swell at 16 seconds, but it’s just too big for this spot, even with lighter wind. Don’t waste your time.
We finally get a break. Friday morning, August 14th is the real deal. We’ve got a 7ft WSW groundswell (16 seconds), and the wind is light and cross-off from the NE. The water is clean, and the wave energy is a solid 1938. This is a proper session for the experienced crew. The sets will have some punch, and that offshore breeze will keep the faces clean. Heads up, this place can get crowded sometimes, so paddle out early.
The next standout is Saturday afternoon, August 15th. The swell drops a touch to 6ft from the W, but the period is still a solid 14 seconds. The killer here is glassy conditions. A total sheet of glass. The wave energy is still good (1463), and it’s going to be a dream to paddle out. Another one for the experienced surfers.
And it keeps going into Sunday, August 16th. Both morning and afternoon are showing glassy conditions with a 8ft swell from the W. The period is 13-14 seconds, and the energy is up around 2031-2382. This is a fantastic run of clean, powerful surf. If you can get out, this is the weekend.
After that, it turns ugly again. Monday the 17th brings a huge 10ft, 17-second swell, but the wind goes onshore and the conditions fall apart. The wind ramps up through Tuesday and Wednesday, with strong onshore winds and a lot of rain. Saturday the 22nd sees another 10ft pulse, but it’s too big for this break.
So, to wrap it up: the first week is a total write-off. The real action is a tight window from Friday the 14th through Sunday the 16th. Thursday the 13th afternoon might be a sneaky one, and the 15th and 16th are looking perfect with glassy conditions. Don’t miss it.
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.
