The Lowdown
Alright folks, Rusty here, staring down the long-range charts for Bonza Bay. Let's cut through the noise and get to the good stuff.
The first few days are a write-off, a real shame. Wednesday the 29th is a non-starter, with a weak 4ft SSW swell and a cross-onshore wind kicking up bumps. The combined energy is a measly (1007). We’ve got a frustrating gap from there, with nothing worthwhile until we hit the back half of the following week.
Now, hold on to your leash, because the real standout window is shaping up for the 12th of August. Wednesday morning is looking like the pick of the entire 16-day run. We’ve got a solid 8ft S swell rolling in, with a clean offshore wind (WSW) and a light breeze. The combined energy is a solid (1720), which is proper strong. That’s a lot of water moving, so this is strictly for the experienced crew – beginners will be out of their depth. The swell direction (S) is a good match for the optimum here, and the cross-offshore wind is going to have those lines looking like glass. It’s a long way out, so don’t book the day off work just yet, but it’s a promising one.
Before that, Saturday the 8th of August has some potential if you’re desperate. The morning session shows a 6ft east swell with a light offshore (N) wind and clean conditions. The combined energy is (883), so it’s got some push, but it’s not a world-beater. The period is short though, at 8 seconds, so it’ll be a bit fat and weak on the face. The afternoon gets blown out by a 28 mph westerly, so get your surf in early.
The 10th of August is another one to note. Monday afternoon sees a glassy 3ft SSW swell with no wind at all. The combined energy is weak (529) but for a small-wave board, it’ll be clean and fun if you’re just looking for a glide.
The river mouth at Bonza Bay is a fickle beast, and it’s rarely consistently pumping for long. Most of the 16-day window is a mix of marginal conditions, poor wind, or just no swell. The 12th of August is the one to circle on the calendar. The rest is for the die-hards.
Rusty.

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.
