The Lowdown
Alright, folks. Rusty here. Let’s take a look at what’s shaping up for Bonza Bay.
Initially, it’s pretty grim. The first few days are a write-off with messy cross-shore winds and lumpy conditions, so don’t bother paddling out for a while. The wait stretches right through the first week. There’s a glimmer of hope on the horizon, but you’ll need to be patient.
The real standout comes on Sunday, the 13th of September. The morning is still a bit rough with a 8ft east swell and cross-shore wind, but the afternoon is where it’s at. The wind swings light and cross-offshore, cleaning things right up. You’ve got a solid 6ft easterly swell rolling in with a moderate period of 10 seconds, and the combined energy is pumping at 1208. It’s going to be clean, and the water temp is sitting around 66°, which is pretty normal for this time of year. This is the best session on offer, no question.
Another option to keep an eye on is Tuesday the 15th of September. The morning brings a 6ft south-southwest swell with a longer 13-second period, pushing a combined energy of 1376. The wind is light and cross-shore, so it’s not perfect, but there’s plenty of push. It’s a decent backup for experienced surfers, but the 13th is the real winner.
The 20th of September looks like it’s going to be too big for most, with an 8ft south-southeast swell and strong cross-shore winds. That’s expert territory, and even then, it’s going to be lumpy and messy.
Bonza Bay is a river mouth, so keep in mind that long-period swells can sometimes break a bit straight. But for the 13th, with a clean offshore wind, it’s going to be worth the wait.
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.
