The Lowdown
Alright, folks, Rusty here. Let’s have a look at what’s on the cards for Bonza Bay.
First things first, the water temp is sitting at 64°, which is a bit colder than normal for this time of year, so don’t forget the extra rubber if you’re heading out.
The forecast starts with a bit of a slow burner. The first real chance to get wet comes Friday morning, the 7th of August. That’s when we’ve got a 4ft SSW swell rolling in with a 12-second period. The kicker is the wind – glassy, absolutely dead calm. That’s a major positive. It’s going to be clean, but the energy is moderate (443) and the swell isn’t huge. It’s a session for the patient surfer who wants a few smooth lines.
The real standout window is Saturday morning, the 8th of August. The swell jumps a touch to 4ft from the SSW, with a nice 14-second period giving it some real grunt. The energy is up to 691 (moderate), and again, we’ve got glassy conditions. This is your best bet of the whole outlook. The waves will be clean, lined up, and with that longer period, it’ll be a proper groundswell. It’s a point break setup here, so it should handle that longer period nicely. Just keep in mind the crowds are *sometimes* an issue, so you might have company.
Things get a bit rowdy after that. Sunday the 9th sees the swell pushing 5ft to 7ft, but the wind swings onshore and howls. The combined energy hits 1067 (strong) on Sunday morning and 1486 (strong) in the afternoon, but with a strong cross-onshore breeze, it’s going to be messy and lumpy. That’s more of a kite day than a paddle day, to be honest.
Monday the 10th brings a big pulse from the SSE, 12ft, but the period drops to 9 seconds. That’s a lot of water moving (2003 energy), but with a cross-onshore wind, it’s going to be a beast. Only for the experts if anyone’s keen, but it won’t be pretty.
After that, the middle of the week is a mix of junky, cross-shore wind and messy swell. The energy stays high through Tuesday and Wednesday, but the wind is from the NE, cross-shore, and up to 19 mph. The swell direction shifts to the E, which is not the optimum (S is best here), so the quality will be poor. It’s choppy, lumpy, and hard to love.
The second week is a bit of a write-off for quality. There’s a pulse on Thursday the 13th that’s too big for the break (10ft from the E, 3077 energy), and the wind is a fresh cross-shore. Not a good fit. From the 14th onward, it’s a lot of onshore junk, small swell, or cross-shore chop. The 18th of August has a small 3ft SSW swell with a 13-second period and a clean, cross-offshore wind, but the energy is moderate (605) and the size is tiny. It’s surfable but very ordinary.
There’s a gap of several days with no real recommendations after the 15th, until the 21st of August when a tiny 3ft E swell shows up with a clean wind. But it’s barely enough to get excited about.
So, to wrap it up: your best bet is Saturday morning, 8th of August. Glassy, 4ft SSW groundswell, 14-second period. Get out there early before the crowds show up.
Rusty.

Information about the Bonza Bay Surf forecast
The above surf forecast table for Bonza Bay provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Bonza Bay can be found by selecting the local surf guide option on the grey menu. Our Bonza 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 (Bonza 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 Bonza 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.
