Bonza Bay Surf Forecast and Surf Report

Alright, let’s get into it. Rusty here. The next couple of weeks at Bonza Bay have got a bit of everything—clean windows, total washes, and even some absolute beasts that’ll only be for the brave. Let’s break it down.

The first few days are a write-off for any decent wave riding. Tuesday the 25th and Wednesday afternoon are choppy, messy, and not worth the paddle out. The swell is there, but the cross-shore wind just chops it all to bits.

Things finally turn around on Wednesday the 26th. That morning is where you want to be. The wind goes glassy, dead calm, and we get a solid 7 ft south swell rolling in with a long 17-second period. The combined energy is pumping at 2864 – that’s proper grunt. This is a groundswell, so at a river mouth like Bonza Bay, it might straighten out a touch, but with glassy conditions it’s going to be clean, powerful, and a real treat for experienced surfers. This is the standout of the whole forecast. Crowds are possible here, so get in early.

Thursday the 27th is a write-off with howling 28 mph winds from the NE. Ugly.

Then Friday the 28th morning gives us a second chance. 6 ft east swell at 10 seconds, with a light offshore breeze from the NNE. Clean conditions. Combined energy is 1081 – moderate but solid. It’ll be a fun, manageable wave, not as heavy as Wednesday but way more user-friendly. A good session for the intermediate crew.

Saturday the 29th is marginal, and from Sunday the 30th through to Tuesday the 1st of September the quality drops right off. Weak swells, onshore winds, and tiny waves. There’s a gap of several days with no real recommendations here.

Wednesday the 2nd and Thursday the 3rd are only marginal at best. Small swells, cross-shore winds, just not worth blocking out the calendar.

But then we get two absolute big-boy days. Friday the 4th and Saturday the 5th of September. Friday morning sees a massive 13 ft SSW swell arriving with an 11-second period. Combined energy is a staggering 6098. The wind is offshore and clean, but this swell is too big for this break – only for experts, and even then, it’s going to be a handful. Saturday the 5th morning is a bit smaller at 10 ft, but still huge and clean.

After that, we settle back down. Monday the 7th of September morning gives a solid 6 ft SSW groundswell at 16 seconds, with light offshore wind. Combined energy is 2053 – strong. Clean again. Another nice session for experienced surfers.

The rest of the second week fades into smaller, less exciting swells.

Water temp is not given in the data, so I’ll skip that.

Overall, the absolute best on offer is Wednesday the 26th of August morning – glassy, powerful, long-period south swell. If you can’t make that, Friday the 28th morning is a solid second, and the big clean swells on Friday the 4th and Saturday the 5th of September are for the hardcore only. Keep an eye on that long-range stuff; it’s promising but things can shift.

Rusty.
