Bonza Bay Surf Forecast and Surf Report

Alright, folks, Rusty here. Let’s be real about the next couple of weeks at Bonza Bay. This is a river mouth setup, and it’s a bit of a mixed bag. We’ve got some energy coming through, but the wind is going to be a persistent headache for most of the run. The water temp is sitting around 66°, which is just a touch cooler than average for this time of year, nothing too wild.

The first real window of surf we see kicks off on Tuesday, the 8th of September. We’ve got a 5ft swell rolling in from the east with a short, weak period of 8 seconds. The combined energy is moderate at 532, but the wind is a cross-onshore breeze, making it choppy. It’s not great, and the afternoon just gets messier. Wednesday and Thursday are much the same story—small, short-period east swell getting chopped up by the wind. The scores are low here.

We hit a bit of a lull in quality through the middle of the week. Friday the 11th sees a 14-second groundswell from the south-southwest, but it’s tiny at 2ft. The energy is still weak at 200, and the wind is cross-onshore again. It’s a tease. The weekend continues with the same pattern: wind-ruffled east swell around 4ft to 5ft, but the period is short and the conditions are poor.

Now, here’s where it gets interesting, but not for the faint of heart. On Friday the 18th of September, the swell really fires up. We’re looking at a massive 15ft swell from the south-southeast with a solid 11-second period. The combined energy is a beastly 4994. The wind is light and offshore in the morning, which would be perfect, but honestly, the swell is way too big for this river break. This is expert-only territory, and even then, it’s pushing the limits. The same goes for Saturday the 19th with 10ft swell. Unless you’re a pro, sit this one out.

The final stand-out, and the only one I’d really call a proper surf session for the average surfer, is on Sunday the 20th of September. The swell drops to a more manageable 7ft from the southeast, with a 12-second period that gives it some punch. The combined energy is still strong at 1621. But the real kicker is the wind: a fresh 19 mph offshore breeze from the west-southwest. That’s going to groom the waves into clean, lined-up walls. This is your best bet, but it’s still a big, powerful swell, so it’s one for the experienced crew. Expect crowds here, as it’s the only really clean window in the whole 16 days.

After that, we go back to the same old story: choppy, cross-onshore wind and diminishing swell through the end of the month. Not much to write home about.

Rusty.
