The Lowdown
G’day, I’m Rusty, and I’m lookin’ straight at the charts for Bonza Bay. This is a tough stretch ahead, folks, with a whole lotta nothing in the first week. The water’s at a pleasant 67° right now, but we’re runnin’ about 1° cooler than what’s typical for this time of year, just a tick off normal.
We start off Thursday the 13th with a solid swell hitting the coast—combined energy is a moderate 810—but it’s a 2ft job from the SSW, and that stiff 30 km/h cross-shore wind out of the NE has got it lookin’ lumpy and chopped. Forget it. Friday and Saturday aren’t any better: that swell picks up to 5ft from the E on Friday morning with a short 7-second period, but it’s still cross-shore wind and messy. The energy drops to 340, and it’s just poor. Saturday morning’s a 4ft E swell with a bit more shape at 8 seconds, but the cross-shore wind and marginal quality mean it’s not worth paddlin’ out. Sunday through Tuesday sees similar drivel—small waves, cross-shore breezes, and scores that stay firmly in the doldrums.
Then we hit Wednesday the 19th, and things get ugly with onshore winds and rain, though there’s a 6ft SSW swell with a solid 10-second period and energy at 813. That southerly wind is blowin’ straight onshore, though, so it’s gonna be a mess for a surfer—probably better for a kite. That trend holds through to Friday the 21st: more rain, onshore slop, and nothing clean.
Now, here’s the standout—Saturday the 22nd. The morning fires up with a tiny 2ft SSW groundswell with a very long 13-second period, and that combined energy is 345. But the magic is the wind: dead glassy, 0 km/h out of the ENE. That’s gonna be clean as a whistle at the river mouth. It’s a small wave, but for a patient soul on a longboard, it’ll be a fun little window before the afternoon turns to slop with 7ft onshore junk. Crowds can be a factor here, so get in early.
Next up, Sunday the 23rd has a 5ft SSW swell with a very long 15-second period and energy at 1173—that’s a lot of power. But it’s light onshore wind, so it’s marginal; the river mouth might hold some cleaner lines if you’re picky. Then we finally get a real winner: Wednesday the 26th. This is the best on offer. You’ve got a 8ft E swell with a moderate 10-second period, combined energy at 1048, and a light cross-offshore breeze out of the N at 10 km/h. That’s clean, punchy surf for the experienced crew. Anything over 8ft is expert-only, but at 8ft it’s still solid—don’t take a foamie out there if you’re not confident. The afternoon gets lumpy again, so make it a morning mission.
Thursday the 27th drops to a 6ft E swell with energy at 741 and a cross-shore breeze, still rideable but not special. After that, it fades into poor again through Friday the 28th. So for the whole 16-day run, that Saturday the 22nd morning and Wednesday the 26th morning are your only real chances—promising but the later one’s a long-range call, so keep an eye on it.
Rusty out.

Information about the Bonza Bay Surf forecast
The above surf forecast table for Bonza Bay provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Bonza Bay can be found by selecting the local surf guide option on the grey menu. Our Bonza Bay surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Bonza Bay) regularly then make a mental note of the wave energy from the surf forecast table each time you go. 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. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
