The Lowdown
Alright folks, Rusty here. Let’s get stuck into the surf outlook for Bonza Bay. The next couple of weeks are a mixed bag, with a whole lot of average or downright messy conditions, but there is one brief window that looks like it could be a ripper.
The first few days are pretty forgettable. The water temp is sitting at 66°F which is about normal for this time of year, nothing wild there. We’ve got a bit of swell around, but the wind is just not playing ball early on. Tuesday morning the 1st of September has a tiny 3ft easterly swell with a 10-second period, but the wind is a cross-onshore, making it a bit of a struggle. The combined energy is weak (240), and it’s a write-off. The afternoon is a little bigger at 3ft, but the direction is all over the shop and the quality is still marginal.
Wednesday the 2nd and Thursday the 3rd are much the same story. The swell picks up a bit, with Wednesday morning offering 5ft from the SSW with a nice 14-second period, which gives it some decent energy (975). But the wind stays cross-shore, putting a chop on the face. We get a few days of this – a bit of size, but the wind keeps it from being clean. By Friday the 4th, it gets messy – we’re looking at a big 13ft swell from the SSE, but it’s accompanied by strong onshore winds of 15 mph. The combined energy is massive (5112), but the conditions are poor. This is more of a kite-surfing setup than a clean paddle session.
Now, here’s the standout. You have to wait for it. Tuesday morning the 8th of September is the one to circle on the calendar. The swell drops to a solid 5ft from the SSE, with a long 12-second period, giving it a nice groundswell feel. The combined energy is moderate (1028). But the real kicker is the wind. We’ve got a light offshore breeze from the north, creating clean, glassy lines. The report says it’s excellent surf conditions for experienced surfers. This is a rare gem in the forecast. The break is a river mouth, and with that long-period swell, it will be peeling nicely. The wind is a cross-offshore, so it’ll be clean. Keep in mind that the crowds are listed as “sometimes”, so you might have a few locals out, but it’ll be worth it.
After that, the second week goes downhill again. The wind picks up, and the swell becomes inconsistent. By the 12th and 13th of September, we get fresh breezes and lumpy cross-chop, making it a write-off. The swell is small and weak, with combined energy dropping to around 150. The 14th sees a bit of a bump from the south, but it’s short-period and choppy. The 15th and 16th are a bit of a mess, with strong winds and rain showers, giving us a lumpy, wobbly ocean. There’s no real quality to grab onto out there.
Bottom line: The only true standout is the morning of Tuesday the 8th of September at Bonza Bay. Get on it if you can. The rest of the 16 days is a lot of wind and chop, so don’t get your hopes up for the rest of the period.
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.
