The Lowdown
G'day, Rusty here. Let's get into what's cooking at Bunbury Bay for the next couple of weeks.
We're looking at a slow start, but things get real from Sunday afternoon. The water is about average temp for the season, nothing wild.
The sweet spot kicks off Sunday afternoon, 6 September. Bunbury Bay is getting a 2ft groundswell out of the WSW, with a 13-second period. Wind is clean offshore from the SE at 9 mph, and that's a proper treat. The wave energy is pumping at a moderate 1966. This is the best session of the whole run – glassy, clean, and a solid size for a beginner-friendly spot. It's a bit on the big side for total beginners at 2ft, but it's still workable. Just keep in mind that crowds are possible here.
Monday, 7 September, keeps the good times rolling. The morning serves up a 3ft W swell, 16-second period, and that same sweet offshore SE breeze at 9 mph, giving us clean, easy conditions. The afternoon drops to 2ft but stays clean with a light ESE breeze. The energy is strong, hitting 2194 in the morning.
Tuesday, 8 September, brings a bigger pulse: 3ft in the morning from the WSW, with a 17-second period. The wind is still offshore from the ESE, but it's stronger at 16 mph. This is getting into expert territory size-wise, and the wave energy is ripping at 3029. The afternoon is still good for experienced surfers at 3ft, with a moderate offshore breeze.
From Wednesday, 9 September, the wind shifts cross-offshore, and while the swell is still a solid 2ft, the conditions are less perfect. The energy drops to 1766. Still surfable, but not the peak.
Thursday, 10 September, sees the swell back off to 2ft, and the wind goes glassy in the afternoon, giving us a tiny, clean wave. The energy is down to 619. It's a quiet day.
Then we hit a rough patch. From Friday, 11 September, through to Wednesday, 16 September, the wind turns onshore or cross-onshore, and it gets messy. The swell is there, but it's not worth the paddle. There's a brief window Monday, 14 September, with a clean 3ft swell and very light wind, but the onshore chop makes it marginal.
The big news is Sunday, 20 September. The swell is pumping at 4ft from the WSW, with a very long 20-second period. The wind is light cross from the SSW, so the lineup could be clean. But the wave energy is massive at 9408. The problem is, this swell is just too big for Bunbury Bay – it's a beginner-friendly spot, and 4ft is way over the top for most. This one is for the absolute experts only, and even then, it's a big call.
The outlook ends with a windy Monday, 21 September, with a 3ft swell and strong onshore winds, so it's a write-off.
So, to sum it up: your best bet is Sunday afternoon, 6 September, through to Tuesday afternoon, 8 September. The standout is Sunday afternoon – clean, offshore, and a solid 2ft swell. The rest of the period is either too messy or too big for the spot.
Stay stoked, and I'll see you out there.

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.
