Bonza Bay Surf Forecast and Surf Report

Alright, Rusty here. Let's take a look at what’s coming our way for Bonza Bay.

Right off the bat, the first two days of the forecast, Friday July 3rd and Saturday July 4th, are out of reach for most of us. We’ve got a big, powerful SW groundswell pushing in, but it’s just too much muscle for this river break. Friday morning sees a solid 10ft SW swell with moderate energy (4172), and a strong cross-off wind. It’s clean, but it’s too big. The afternoon swings cross-on with a 10ft SSE swell. Both sessions are for experts only, and honestly, the setup looks more interesting for kite surfing than paddle surfing. The water's also a bit colder than normal at 65°F, which is a couple of degrees off the average.

The first real standout is Saturday July 4th morning. The swell has dropped to a still-chunky 8ft from the SE, with a 12-second period. The wind is glassy. That's the key. Glassy conditions on a 8ft groundswell, with strong energy (1773) behind it. This is the call for experienced surfers only—it’s going to be big, powerful, and clean. Very clean. Just know the crowd factor is "sometimes," so you might not have it all to yourself.

Sunday July 5th morning (3) is a great option for a broader range of surfers. The swell has backed off to a much more user-friendly 5ft from the SE, with a 12-second period and a light cross-off breeze. The combined energy is moderate at 638. It’s a good, clean morning for intermediate surfers. Nice, lined-up waves from that long-period groundswell.

There’s a lull in the middle of the week. Monday July 6th and Tuesday July 7th drop right off. Tiny, weak swell (under 3ft and low energy, like 191 and 311) and mostly crummy wind. Not worth paddling out for.

Then the pattern shifts. Thursday July 9th morning (9) brings a significant, powerful S groundswell back in. We’re looking at a 8ft S swell with a 11-second period and glassy conditions. The combined energy is very strong at 2768. This is another expert-only session, but with those winds, the river mouth is going to be an absolute freight train. This is a standout for the big-wave crew.

Friday July 10th morning (10) is the next gem. It settles to a 6ft S swell (12-second period), with glassy conditions and moderate energy (857). Perfect for the experienced intermediate surfer wanting a powerful, clean wave without the extreme size of Thursday. This is another strong call.

After that, the surf quality gradually fades. Occasional chest-high S swells with decent period (4ft to 5ft, 12 to 13 seconds) hang around through the second week, like Monday July 13th morning (13), but the winds are more of a gamble—sometimes glass, sometimes variable. For the most part, it’s marginal to poor.

One more promising window shows up on Friday July 17th morning (17) with glassy winds and a tidy 3ft SSW swell with a very long 15-second period. Not huge, but super clean and silky from a classic groundswell. A reef or point break would love that long period, but at Bonza Bay’s river mouth, the waves might be a little straight. Still, with glass and a perfect offshore wind, it’s worth a look.

The very end of the run, Saturday July 18th (18), turns into a blown-out, messy windswell with a 8ft E swell and a short 9-second period. Fresh cross-off wind, but lumpy and unappealing. That’s a no-go.

So, you want the pick of the litter? Get on the Saturday July 4th morning for the gnarly, glassy, big-wave session, or the Thursday July 9th morning for the biggest, cleanest energy wave. If you want something a bit more manageable, the Friday July 10th morning is your window.

Rusty.
