The Lowdown
G'day, I'm Rusty. Let's talk about what's on the menu at Bunbury Bay.
Right, there's a bit of a slow start here. The first real chance of a surf isn't until Sunday afternoon, the 19th. Before that, we've got a big, ugly, windy swell on Saturday the 18th that's blowing up to 12ft but with a nasty cross-onshore wind, making it a total mess. You wouldn't want to paddle out in that.
The standout period is actually a nice little window from Sunday afternoon through to Wednesday morning. The best of the best looks like Sunday afternoon, the 19th. The swell drops to a clean 6ft from the west, with a decent 14-second period that'll give the waves some punch. The wind is going glassy, as still as it gets, so the surface will be like a mirror. You're looking at moderate wave energy (1047) and it's a beginner-friendly size, so it's a great time to get out there.
Monday the 20th is also a cracker, with a smaller 4ft to 3ft WSW swell and glassy conditions both morning and afternoon. The water temp is 65°, which is about average for the time of year, so a spring suit should be fine.
Tuesday the 21st morning brings a clean 4ft swell with a light cross-offshore breeze from the south, and Wednesday the 22nd morning has a clean 5ft swell with a light offshore from the ESE. These are all good, clean, manageable waves.
We then hit a bit of a flat spell from Thursday the 23rd through to Saturday the 25th, with small 3ft to 4ft swells and light cross-shore winds. Not terrible, but nothing to get excited about. Then on Sunday the 26th, the swell ticks up to 7ft to 8ft with a very long 18-second period from the west, but the wind is cross-shore or cross-on, and the energy is strong (3135 to 3213). It's a big, powerful groundswell that might be a bit too much for the beach break, but if you're an expert, it could be worth a look. That whole week following has some big, windy days, including a massive 16ft swell on August 1st that's way too big for this spot.
Overall, the best bet is definitely Sunday arvo the 19th, with Monday the 20th and Tuesday the 21st morning as solid back-ups. The crowds are marked as "sometimes" here, so you might have a few others with the same idea on those clean days.
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.
