The Lowdown
G'day, I'm Rusty. Let's have a look at the next 16 days at Bonza Bay.
It's a pretty patchy run ahead, to be honest. The first week is mostly a write-off, with a lot of marginal, cross-shore wind and lumpy conditions. The swell is there, but it's just not clean. Things start to get interesting around Saturday, 9th August, when a big swell arrives, but it's a monster. We're looking at 10 ft to 15 ft range from the south and southeast, with strong offshore winds. That's expert territory only, and it will be too big for most. The combined energy is pumping, hitting 4512 on Monday morning, and it's just too much for the river mouth.
The real standout is Wednesday, 12th August. The morning session is the pick of the entire forecast. The swell drops right back to 4 ft from the SSW, with a super long 19-second period. That's proper groundswell that will wrap in nicely. The wind is glassy, and the water temp is a normal 69° for this time of year. It's excellent for experienced surfers, with moderate energy (1734). The afternoon is a bit smaller at 5 ft, still a long 17 seconds, but the wind goes cross-onshore, so the morning is the one to nail.
Earlier in the week, Saturday, 8th August morning also has some glassy conditions with 3 ft SSW swell at 14 seconds, but it's weaker. And then the tail end of the run, Saturday, 15th August morning, shows a clean 3 ft SSE swell with a 13-second period and light offshore winds, which is a nice little window for a cruise.
Crowds can be an issue at Bonza Bay sometimes, especially on a good day. The first week's conditions are mostly poor, so it might be a bit quiet. Don't get too excited about the big stuff around the 9th-11th unless you're a seasoned charger. The river mouth setup means that long period groundswell from the SSW on the 12th might actually break a bit too straight for a beach break, but it's a river, so it should still offer some nice shape.
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.
