The Lowdown
Alright crew, Rusty here with a look at what's coming up for Bunbury Bay over the next couple of weeks. Gotta be straight with you from the start: this forecast is a tough one. The water is sitting at 61°F, which is a bit colder than we'd usually expect for this time of year, so don't forget the extra rubber.
The short-term is a write-off, I'm sorry to say. For the first few days, from Tuesday the 4th to the end of the week, the wind is a persistent problem. It's coming from the west and southwest, smacking us cross-onshore, and the waves are just a messy, choppy 6 ft to 8 ft. The swell energy is moderate, but it's all over the shop. There's nothing to get excited about here.
We hit the weekend on Saturday the 8th, and the swell starts to pump up, but it's a case of too much of a bad thing. We're looking at a serious 12 ft to 13 ft of WSW swell, with a combined energy roaring into the thousands (5,313 to 7,008). That's expert territory, and with a strong cross-shore wind, this setup is honestly looking a lot more interesting for kite surfing than paddle surfing. The conditions are messy and way too big for this spot.
The pattern keeps up through Sunday the 9th and into next week. The swell hangs around 8 ft to 10 ft, but the wind just won't clean up. It's a textbook case of "marginal" at best through the 10th, 11th, and 12th of August, with gentle cross-onshore winds keeping the surface bumpy. The Monday morning of the 10th is perhaps the least worst option, with a 7 ft WSW swell (energy 1,993) and a light cross-shore breeze, but it's still a gamble.
The real standout, if you're an expert and you're brave, is looking way down the line. The 18th and 19th of August are showing some serious potential. We've got a massive, long-period groundswell from the west, with heights hitting 13 ft on the 18th and 12 ft on the 19th. The combined energy is very strong, hitting 10,256 on Tuesday morning. But here's the catch—the guidance says the swell is predicted to be too big for this break. It'll be a raw, powerful, and dangerous affair. The winds are much lighter, almost glassy at times, which would make the surface clean, but the sheer size will make it a mission. This is a distant, promising but less certain call for the real experts only.
Bottom line: For the next week and a half, it's a waiting game. The potential for a big, clean swell on the 18th and 19th is the only flicker of light, but it's a light for the experienced crew only.
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.
