The Lowdown
Alright folks, Rusty here, giving you the lowdown for Bunbury Bay for the next 16 days. Gotta be straight up – the start of this run is a bit of a right-off. We’ve got some serious energy pulsing in, sure, but the wind and conditions are just not cooperating. Buckle up.
It’s a slow burn to get anything decent. The first couple of days, Saturday the 12th and Sunday the 13th, have us sitting on some real grumpy conditions. The swell is building through a solid 8ft, pulling in from the W with a long 16-second period, packing a ton of energy (3329). But with a howling 16 mph cross-on shore, it’s just a mess – choppy and blown out. Not worth a paddle. Water temp is sitting at 62°, which is a touch cooler than average for this time of year, so a decent wetsuit is the go.
The only real window of quality in the first week, and the standout of the whole outlook, hits us on Monday the 14th. The glassy, clean ESE offshore wind arrives, grooming the 7ft W swell (14-second period) perfectly. The wave energy is still substantial (1668), but it’s clean, powerful, and lined up. This is for experienced surfers, though. At 7ft with that period, the paddle-out might have some lulls, but the waves will have proper shape. This is your day. Crowds can be a thing here sometimes, so get in early.
Tuesday the 15th still offers some clean options with an offshore breeze and a dropping swell (6ft to 5ft), making for a fun, less intense option. By Wednesday the 16th, things flatten right out (3ft to 3ft) and go glassy in the arvo, but it’s small and weak.
The pattern goes to junk again from Thursday the 17th through to Saturday the 19th. Strong winds, rain, and blown-out conditions dominate. On Saturday the 19th, the swell pumps up to a massive 12ft (5029 energy!) but the cross-off wind is the only saving grace – it looks more like a kite-surfing playground than a paddle-surfing one. Too big, too raw. Sunday the 20th has a brief moment of glassy perfection with a 7ft W swell, but the rest of the week is a mix of onshores and small, weak waves.
Looking further out, the second week is a real gamble. Monday the 21st has clean-ish 6ft W swell, but with light cross-shore winds, it’s an average affair. Wednesday the 23rd could be a sleeper hit, with a clean ESE offshore and a tidy 4ft WSW swell, but it’s not as powerful. The best bet in that second week is likely Friday the 25th with a 6ft WSW swell, but it’s let down by a cross-shore breeze kicking up a chop.
Overall, if you can, make it for Monday the 14th. That’s your call to arms. The rest is waiting, watching, and picking the scraps when the wind plays nice.
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.
