The Lowdown
G'day, I'm Rusty. Let's have a look at what's on the cards for Bunbury Bay over the next couple of weeks.
First up, the water is sitting at 61.2°, which is a bit colder than normal for this time of year. The first real chance of a decent surf doesn't come until Thursday morning, the 13th of August. We've got a solid 6.2ft groundswell from the WSW with a very long 17-second period, and the wind is dead calm – glassy. That's a beautiful combination for a point break like this. The combined swell energy is strong at 1886, so there's plenty of grunt in the water. This is the standout session of the whole forecast. The wave direction is a near-perfect match for what this spot likes to see. Keep in mind that with a period this long, the sets will be clean and powerful, but there will be longer gaps between them. It's a good day for experienced surfers, as the size is pushing into the 6.2ft range.
Friday morning, the 14th, is also very clean. The swell drops a touch to 6.2ft from the WSW with a 16-second period, and we have a light offshore breeze (NE). The combined energy is still strong at 1708. It's another excellent option for experienced surfers. The afternoon sees conditions turning more mixed with a cross-shore breeze, so get it in the morning.
Saturday the 15th has a smaller 4.6ft WSW swell, with glassy conditions in the afternoon. The combined energy is moderate (777). This is a good, mellow window for beginners to get a few.
Now, don't get too excited about the Sunday the 16th, as the wind picks up from the NNE, making it a bit messy. Then Monday the 17th is a write-off. We're looking at a strong 19-25 mph onshore wind with a 9.8ft WNW swell and an enormous combined energy of 5194 to 5923. The setup will be more interesting for kite surfing than paddle surfing. It's dangerous for anyone but the top experts, and even then, it's poor quality.
The following week is a mixed bag. Tuesday the 18th has a big 8.2ft W swell, but the wind is cross-onshore. Wednesday the 19th and Thursday the 20th see the swell jump to 11.5ft and even 13.1ft, which is too big for this break. The combined energy is off the charts (9498 on Thursday afternoon), but it's a no-go for us. Friday the 21st is messy with onshore winds.
Looking further out, Saturday the 22nd of August has a promising window. We have a 7.9ft WSW swell with a 12-second period and a clean, cross-off wind from the SSE. The combined energy is strong (1770). It's another good option for experienced surfers. The rest of that week fades with smaller swells and more wind.
So, to keep it simple: your best bet is Thursday morning the 13th. That's the one to circle. Friday morning the 14th is a close second. If you're a beginner, wait for the smaller, glassy afternoon on Saturday the 15th. The following Saturday the 22nd also shows promise.
Short Range ForecastMostly dry. Very mild (max 17°C on Fri afternoon, min 10°C on Thu morning). Wind will be generally light. | Days 4-6 Weather SummaryModerate rain (total 10mm), heaviest on Mon morning. Warm (max 22°C on Sun afternoon, min 13°C on Sat morning).

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.
