The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on offer for Bunbury Bay over the next couple of weeks.
Right off the bat, we’ve got a bit of a slow start. The first few days are pretty average with a weak, short-period WSW swell around 4 ft and a light cross-shore wind. The water is sitting at 62°, which is a bit colder than normal for this time of year – you’ll feel that chill. The real action doesn’t kick off until Monday morning, the 24th of August. That’s the first standout. We’ve got a clean 5 ft swell from the west with a 14-second period, and the wind is glassy, absolutely dead calm. It’s going to be a beautiful morning, with moderate wave energy (1033). The swell direction is a touch off the optimum, but when it’s that clean, you don’t complain. Crowds are a possibility here, so get in early.
Tuesday the 25th gets messy with a strong NW wind, so we’ll skip that. Wednesday the 26th brings a massive 12 ft west swell with a very long 19-second period. The combined energy is huge (8209), but that’s too big for this break. It’s an expert-only situation if you’re brave, but the wind is clean, so it’ll be a sight to see. For the average punter, it’s a no-go.
The next real standout is Saturday the 29th of August. The afternoon session is looking excellent. You’ve got a 4 ft groundswell from the WSW with a long 16-second period, and the wind swings offshore from the ESE at just 3 mph. That’s clean, glassy conditions, with strong wave energy (1462). This is the pick of the first week for experienced surfers – the long period will make for some nice, lined-up waves, but it might be a bit too straight for the beach break, so look for a bank.
We then hit a long, dry patch from the end of August through to the start of September. The wind is mostly onshore or cross-on, and the conditions are poor. There’s a gap of about five days with nothing worth paddling out for.
However, the second week does have a promising but less certain call. Saturday morning, the 5th of September, is a cracker on paper. We’ve got a solid 8 ft west swell, 14-second period, and the wind is glassy, coming from the WSW at 3 mph. The wave energy is very strong (3022). That’s a big, clean swell, but 8 ft is pushing into expert territory. It’s going to be a powerful, heavy day. The swell direction is good, and the glassy surface will be unreal, but you’ll need to be on your game.
After that, the 6th and 7th of September see another pulse of massive swell, over 12 ft and up to 15 ft, with very strong energy (over 8000). It’s too big for Bunbury Bay, and the wind is onshore, so it’s a right-off for surfing. That’s more of a nasty, lumpy mess for the beach.
The best of the whole period? Lock in Saturday morning, the 5th of September, for the big, glassy west swell if you’ve got the skills. And for a more manageable, but still excellent session, go for Saturday afternoon, the 29th of August.
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.
