The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the cards for the Bunbury Bay stretch over the next couple of weeks.
We’ve got a bit of a mixed bag coming up, but the first real standout is this Saturday morning. The water is a bit colder than normal for this time of year, sitting at 61°F, which is a degree or two off the usual. Don’t let that put you off, though. The swell is coming in from the WSW at 4ft, with a very long period of 19 seconds – that’s proper groundswell energy. The combined wave energy is sitting at 949, which is moderate, but the key here is the wind. It’s an ESE breeze at 12 mph, blowing straight offshore, keeping things glassy and clean. For a beginner-friendly spot that’s fairly consistent, this is about as good as it gets. Expect some proper lines rolling through.
Saturday afternoon picks up a touch, with the swell pushing to 5ft, still from the WSW and still a solid 18-second period. The offshore wind holds, and the energy jumps to 1447. This is excellent for experienced surfers – the bigger, longer lines will be a joy, but it’s getting a bit much for absolute beginners.
Sunday morning the 30th is the other real standout. The swell hits 6ft from the WSW, period still a long 18 seconds, and the combined energy is a thumping 2264. The wind has swung to a light NE at 6 mph, which is a clean cross-offshore breeze. The waves will be well-shaped and powerful. This is the pick of the bunch for the first week – serious groundswell with clean conditions. Just be aware, with that size, it’s really for the experienced crew.
Sunday afternoon sees a drop in quality. The wind shifts to a light W at 3 mph, but it’s cross-onshore, and the period drops to 16 seconds. The swell is still 6ft, but you’ll start to see a few small ripples on the face. It’s still surfable, but not as pristine as the morning.
Monday through to the following Saturday, honestly, it’s a bit of a write-off. The wind goes onshore and strong, or the conditions get messy. The swell sticks around 5ft to 8ft, but the wind is from the NW, W, or WSW, mostly onshore or cross-onshore, with speeds up to 28 mph. The wave energy is high, but it’s going to be choppy and blown out. There’s a period on the 5th of September with a strong 28 mph WSW cross-onshore wind and 8ft swell – that’s more of a kite-surfing setup than a paddle session.
Now, hang in there, because Tuesday the 8th of September morning is a good window. The swell is 5ft from the WSW, with a 16-second period, and the wind goes glassy – a light WNW at 3 mph. The energy is 1382. It’ll be clean and lined up. Tuesday afternoon is even better, with the swell bumping to 6ft, still from the WSW, and the wind turns glassy again. The energy hits 1685. That afternoon session is a true gem.
The following weekend, Sunday the 13th of September morning, is another promising shout. The swell is 6ft from the W, with a long 17-second period, and the wind is a light NE at 6 mph, blowing cross-offshore, keeping it clean. The energy is a strong 1912. It’s a bit of a wait, but that morning looks like it’ll deliver some proper waves for the experienced crew.
So, to cut it short: if you’re a beginner, get out Saturday morning the 29th of August. For the experienced surfers, the standout windows are Sunday morning the 30th of August, Tuesday afternoon the 8th of September, and that Sunday morning the 13th of September. The middle of the week is a loss, but the good windows are worth the wait.
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.
