The Lowdown
G’day, Rusty here. Let’s break down what’s coming for Bunbury Bay over the next couple weeks. Fair warning: it’s a rough start and we’ve got a long, quiet spell before things get interesting. The water’s runnin’ a bit cooler than usual for this time of year, 61°, about 3° colder than average, so you’ll want a thicker wetsuit.
Right now, we’re in a real lull. The first solid chance to paddle out doesn’t show up until the morning of Tuesday 2nd September. There’s a gap of a few days from today with no good surf—just messy, blown-out lines. Tuesday morning offers a 5ft west-southwest swell, period of 14 seconds (decent energy, moderate at 1270), but the wind’s cross-on. It’s marginal and choppy, more of a grovel than a gem.
Wednesday 3rd and Thursday 4th are pretty much write-offs—onshore wind, rain showers, swell pushing over 7ft at times but blown to bits. Thursday 4th has a 7ft west swell but onshore wind kills it.
Now, Friday 5th September is where it starts to get our attention, but not for everyone. The morning shows a 8ft west-southwest swell, long 15-second period, with light cross-on wind—marginal but rideable if you’re keen. The afternoon though, it climbs to a 10ft west-southwest swell, period 16 seconds, combined energy of 3888 (strong). The wind flips to a gentle cross-on, but that size at Bunbury Bay is too big for this break—only for the experts, and even then, it’s a handful. This is a beach break, and a long-period groundswell like that (16 seconds) can make things dumpy and straight. Best bet for big wave crew on Friday arvo, but beginners stay out.
Saturday 6th and Sunday 7th are trashed with strong winds and messy swell.
The real standout, the one I’m getting a bit excited about, is Friday 11th September morning. We’ve got a 4ft west-southwest swell, 14-second period, combined energy at 1036 (moderate). The wind is light cross-off from the east-northeast—clean lines, good shape. The guidance says “expect very good surf conditions.” The swell’s a little under head-high but clean and mellow, and for Bunbury Bay that’s a sweet spot. Crowds are possible here sometimes, but on a Friday morning with these conditions, you might have a few others in the know. This is your pick for the whole outlook.
After that, we get a bit of a chop again, but Sunday 13th September morning is another highlight for experienced surfers: a 8ft west swell, 16-second period, combined energy heavy at 3453, and light cross-off southerly wind. Clean, powerful faces. That’s expert territory.
The run finishes with Monday 14th September morning: 7ft west swell, 15-second period, glassy with a light east-northeast cross-off. Combined energy 1759 (strong). Another clean-skin morning for those who can handle the size.
To sum it up: Friday 11th September morning is the standout—clean, head-high, and fun. Friday 5th arvo and Sunday 13th morning are for the big-wave crew only. Otherwise, it’s a lot of waiting around. Keep your eye on the forecasts, ’cause the second week shows promise.
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.
