The Lowdown
Alright, folks, Rusty here. Let's have a look at what's on the cards for Bonza Bay over the next couple of weeks.
Alright, straight up, it’s a bit of a mixed bag. We’ve got some swell pushing through, but the wind is going to be the main character for a lot of this run. Don't expect a magic carpet ride every day, but there are a couple of windows that’ll get the heart ticking.
The first week kicks off with some size, but the wind is a problem. Friday the 31st of July and Saturday the 1st of August have waves in the 5 ft to 6 ft range from the ESE, but it’s blown out with cross and cross-onshore winds hitting 12 to 15 mph. The combined energy is moderate (808 dropping to 430), but the poor surf conditions make it a write-off. Sunday the 2nd of August pushes up to 7 ft with a longer period, giving a solid 11 seconds and combined energy jumping to a strong 1226, but it’s still cross-shore at 12 to 15 mph. The wave comment is “marginal”, so it’s not looking clean.
The first real standout comes on Tuesday the 4th of August. The morning session is glassy, with a light NE breeze of just 3 mph. There’s a 6 ft swell from the E with a 9-second period, and the combined energy is a solid 906. The wave comment says “expect very good surf conditions”. This is the one to aim for. The water temp is about average for this time of year, so no dramas there.
After that, we drop off a bit. Wednesday the 5th of August is smaller, around 3 ft, but glassy again in the morning, so you could get a fun little board out. Thursday the 6th of August brings a new SSW swell, up to 4 ft, with a long 14-second period. The wind is clean on the morning with a 15 mph cross-off, but the combined energy is only moderate (618). It’s a bit of a wait for the sets, thanks to that long period, but it’s tidy.
The second week gets a bit more interesting. Saturday the 8th of August has a clean morning with a 3 ft SSW swell, 13-second period, and a light cross-off breeze. Combined energy is low at 384, but it’s clean. Then, Monday the 10th of August has a glassy afternoon, with a 3 ft E swell, 9-second period, and combined energy of 259. The wave comment says “expect good surf conditions”. That’s another small but clean window.
The real long-range promise is on Thursday the 13th of August. The morning has a 4 ft E swell with a 10-second period, and the wind is a solid 15 mph offshore from the NNW. The wave comment is “expect good surf conditions”. The combined energy is moderate (458). Then the afternoon gets interesting: a 2 ft SSW swell with a very long 15-second period, and a 19 mph offshore wind from the NW. It’s a fresh breeze, but it’s clean. That long period groundswell will peel nicely on the river mouth setup here at Bonza Bay, but at beach breaks it’d be breaking too straight. It’s a promising but less certain call this far out.
Overall, the best bet is the glassy morning on Tuesday the 4th of August. That’s the standout. The second best is the offshore morning on Thursday the 13th of August. The rest of the time, you’re wrestling with cross-shore wind or small swell.
This is 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.
