Bonza Bay Surf Forecast and Surf Report

Alright, Rusty here. Let’s look at the next couple of weeks for Bonza Bay. This spot is a river mouth, exposed to the south, so it needs the right angle of swell and a bit of luck with the wind to really fire.

For the first few days, we’ve got some serious energy in the water, but it’s just too big. A 10 ft SW swell on Friday, July 3rd is pushing a massive 4012 (moderate to strong combined energy) and that’s just too much for this break. You’d be looking at a washing machine. The wind is crossed up too, so it’s not worth paddling out. The real story starts to change on Saturday, July 4th.

Saturday morning is the clear standout. The swell has dropped to 8 ft from the SE, still a solid groundswell (12 seconds), but the wind goes glassy – totally clean. That combined energy is down to a still beefy 1900 (moderate energy). This is the session for experienced surfers only; it’s powerful and lined up right out the front. The water temperature here is about average for the time of year.

Sunday morning, July 5th, cleans up nicely too. The swell is a more manageable 5 ft from the SE with a light cross-offshore breeze making it clean. That’s a good session for a strong intermediate, with 643 (moderate) energy.

We then hit a flat spell. From Monday afternoon through to Wednesday, July 8th, it’s small and weak, with energy dropping below 300 and wind messing things up. Not worth a second look.

Then on Thursday, July 9th, the south swell kicks back in. 7 ft from the south with a 12-14 second period, but the wind is onshore or cross-onshore, so the quality is marginal. We get a little better again on Saturday, July 11th, with a 5 ft S swell and a cross-offshore breeze. That’s clean and 873 (moderate) energy is a good sign for a fun session.

Now, looking further out to Sunday, July 12th, we see a massive spike: an 12 ft SSE swell with a very long 17-second period. The combined energy hits 7393 (strong). That’s expert territory, and the wind is a strong cross-shore, creating lumpy conditions. It’s still going to be big and grunty.

The following week gets a bit chaotic. Monday and Tuesday, July 13th and 14th, see a shift to a shorter-period E swell (8-9 seconds) with poor wind. The energy drops, and it’s not clean. The best chance in that second week looks like Tuesday morning, July 14th, with a 6 ft E swell and a light offshore breeze making it clean (663 energy). That’s a solid, surfable option for the experienced crew.

The last true standout in this window is Thursday, July 16th. A huge 13 ft SW swell with a 12-second period slams in, putting out 6783 energy. The wind is a strong offshore, so it will be clean but absolutely pumping, and way too big for anyone but the most experienced. A serious day for chargers only.

So, the best on offer: Saturday morning, July 4th for a glassy, powerful SE groundswell for the experienced, and Sunday morning, July 5th for a slightly smaller, clean SE swell for the strong intermediates. The long-range stuff on July 12th and 16th is massive and clean, but promised land for experts only.
