Bonza Bay Surf Forecast and Surf Report

G'day, Rusty here. Look, I've been staring at the charts for Bonza Bay and the honest truth is the first week or so is a bit of a write-off for decent waves. We've got some energy coming through, but the wind and conditions are just not playing ball. We're looking at a long stretch of pretty average stuff until we get to a couple of standout windows that are worth getting excited about, even if one has a serious size warning.

Alright, let's start with the early days. From Monday the 17th through to Saturday the 22nd, it's a tough run. The swell is all over the place—some easterly, some south-westerly—but the scores are low. The wind is mostly cross or cross-onshore, keeping things choppy. Sure, there's energy in the water, especially on Thursday the 20th afternoon with a combined swell energy of 1828, but the 7ft swell is coming in at a messy 14 seconds with a cross-onshore wind. It's just not gonna be any good. You'll be fighting the chop more than riding waves.

Now, here's where it gets interesting. Sunday the 23rd of August is a monster. The morning session is looking at a solid 15ft swell from the SSW with a 14-second period. The combined energy is an enormous 11899. The wind is cross-offshore and clean, which is a beautiful thing to see. The water temp is around average for this time of year, which is fine. But let me be clear: this is for experts only. Anything over 8ft is serious, and 15ft at a river mouth setup like Bonza Bay is going to be a raw, powerful beast. If you're not properly experienced, stay on the sand and watch the show. The swell stays big through Monday the 24th with 10ft sets and that 17-second groundswell. That period is proper long, so expect long lulls between big, setty waves. It's going to wall up and could be unpredictable on a river break. This is the one true standout for the whole run.

After that big pulse, it gets messy again from Tuesday the 25th through to the end of the month. The wind picks up, the swell drops and gets jumbly. We do get a little window on Friday morning, the 28th of August. The swell is small, only 3ft from the SSW at 13 seconds, but the wind is glassy, and the rating is solid. It won't be big, but with those clean conditions, it could be a fun little fish or longboard session with no crowd stress.

So, overall, the forecast is a bit of a mixed bag. Don't bother with the first week. Your absolute standout is Sunday the 23rd for the big-wave crew, and a smaller, cleaner chance on the morning of Friday the 28th. Stay safe out there.
Rusty.
