The Lowdown
Right, folks, Rusty here. Let’s have a look at what’s cookin’ for the next couple of weeks.
Honestly, it’s been a rough stretch for Bonza Bay. We’re lookin’ at a long, lean spell here. Most of the time, the wind is just wrong – cross-shore junk or fresh cross-onshore chop that’s tearin’ the waves apart. The numbers are ugly, and the conditions are just plain poor. It’s gonna take a while to get a proper session.
The one real glimmer in this whole outlook comes on Saturday, August 15th, in the morning. That’s our standout. The swell settles to a clean 5ft from the East, with a short period of 8 seconds. But the wind? Dead glassy. That’s a massive positive. The combined energy is moderate (274), but the lack of any wind chop means the surface will be clean. It’s the only time the “expect good surf conditions” note pops up. It’s a small, short-period east swell, so don’t expect anything with serious punch, but for a Saturday morning paddle, it’s the best we’ve got. The water temp is about 67°, which is a touch cooler than usual for this time of year, but nothing wild.
After that, it’s back to the slog. The wind comes up again, and we’re left with lumpy, cross-shore slop for days. The second week of the forecast is a write-off – no real standout windows, just persistent wind and poor quality. The setups are all beach and river, so with the strong cross-winds on offer, this is looking more interesting for kite surfers than paddle surfers for a lot of the period.
We hit a few days in late August where the swell direction is from the South, but the wind is ripping, so it’s still messy. Just a tough run for Bonza Bay.
Rusty, signing off.

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.
