The Lowdown
G’day, Rusty here. Look, I’m not gonna lie to you – the next couple of weeks are a mixed bag for Bunbury Bay. We’ve got a serious pulse of energy coming through, but the wind’s going to be a stubborn bugger for a lot of it, making things messy. The water’s sitting at 62°, which is pretty much what you’d expect for this time of year, no real surprises there.
The first real chance to get wet doesn’t arrive until Monday the 14th. We’re looking at a solid 6ft of swell thumping in from the WSW, with a nice long 14-second period. That’s real groundswell energy – 1512 (moderate) – and with a clean ESE offshore breeze blowing at 12 mph, the waves will have some shape. This is one for the experienced crew though; at nearly 6ft, it’s got some push. That quality holds through Monday afternoon, too, with the same clean offshore conditions.
Tuesday the 15th is still offering up some fun. The swell drops a touch to 5-6ft from the WSW, still with a long 15-second period. Morning is a little cross-off with an E wind, but the afternoon turns glassy offshore from the ESE at 9 mph. That’s the pick of the early week – clean, lined-up waves.
Wednesday the 16th sees the swell fade to 3ft, but the afternoon goes glassy with a light SSW breeze. It’s small and clean, a nice little window for a log or a mal.
Then the wheels fall off. From Thursday the 17th right through to the 22nd, the wind is a nightmare. We’ve got fresh to moderate cross-onshore winds from the north and west, blowing 12-19 mph, turning what could be a solid 7ft+ swell into a lumpy, choppy mess. There’s plenty of energy in the water – some readings well over 2000 (strong) – but for a paddle surfer, it’s just not worth it. A kiteboarder would have a field day though.
We finally get a reprieve on Sunday the 21st with a clean, light onshore, but the swell’s only 5ft and the conditions are marginal. The real standout comes next week. Mark your calendar for Wednesday the 23rd of September. Morning session is the one: a clean 5ft WSW swell, 16-second period, and a light 3 mph offshore breeze from the ESE. That’s 1135 (moderate) of clean, lined-up energy. This is the best on offer in the whole outlook.
After that, the swell hangs around in the 4-5ft range through to the end of the month, but the wind is inconsistent, switching between cross-off, cross, and fresh offshore. The 28th of September has a small, clean 3ft wave with a moderate offshore, but it’s more of a grovel than a highlight.
The standout is Wednesday morning the 23rd. The swell is 5ft from the WSW, period is a dreamy 16 seconds, and the wind is a light offshore. That’s as good as it gets in this window. Get out there if you can.
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.
