Bonza Bay Surf Forecast and Surf Report

Right, let’s have a look at what’s on offer. I’m Rusty, and I’ve been staring at the charts for this stretch.

Alright, straight up – this isn’t a week for grabbing your board and heading out with high hopes. The next few days are a bit of a write-off for decent waves. The first real chance of anything ridable is on Sunday morning, August 23rd, but even then it’s only marginal.

Sunday, August 23rd we’ve got a 7 ft swell from the SW, but the wind is a cross-off at 12 mph, keeping things clean. The combined energy is strong (1259). Still, the files say the surf is marginal. The water temp is sitting at 66°, which is about 2° cooler than normal for this time of year – nothing crazy, just a touch on the fresh side.

From Sunday afternoon through to Saturday, August 29th, it’s a real struggle. We’ve got waves, but they’re either too small, the wind is onshore or cross-shore, or the period is all wrong. There’s a window on Tuesday, August 25th morning with a 3 ft SW swell, a very long period of 17 seconds, and clean cross-shore wind. The energy is moderate (1056). That long period will make for some nice lines at Bonza Bay (a river mouth), but it’s prone to being a bit straight. It’s a marginal call, though.

A bit of a gap follows, but then we see something interesting on the horizon.

Monday, August 31st morning brings a big 10 ft SW swell with a 12-second period. The wind is cross-shore at 12 mph, and the energy is very strong (3301). The problem? The file says it’s too big for this break. That’s a clear warning – only for the very experienced, and even then, it’s a gamble.

Tuesday, September 1st morning is a tease. The swell drops to 3 ft with glassy conditions – perfect conditions – but the energy is weak (288). It’s a good surf forecast, but there’s just no size.

Thursday, September 4th starts to amp up. The morning has a 6 ft SSW swell, a very long period of 18 seconds, and clean cross-off wind. The energy is strong (2540). This is a promising setup, but it’s a long way out. By the afternoon, the swell jumps to 10 ft, and the file says it’s too big for the break. The same goes for Friday, September 5th (12 ft) and Saturday, September 6th (a massive 16 ft SW swell with 14-second period and energy of 15665). These are big, powerful groundswells, but they are almost certainly going to be too big for Bonza Bay, and the wind is not ideal.

The Standout – If I had to pick a single session to keep an eye on, it’s the Thursday, September 4th morning. The 6 ft SSW swell with that 18-second period and clean wind is your best bet for a proper surf. The energy is solid (2540), and the direction is right. But it’s over a week away, so treat it as a promising possibility, not a guarantee. The days after that are just too big for this spot.

Bottom line: the first week is a dud. The second week has a lot of size, but it’s mostly too big for the break. That Thursday morning is the one to pencil in if you’re desperate.

Rusty.
