Bonza Bay Surf Forecast and Surf Report

Alright, let’s get into it. Rusty here, and I’ve been staring at the charts for Bonza Bay. This is a river mouth set-up that’s exposed to the south, and when it’s on, it’s a gem. But we’ve got a long 16-day window, and it’s a bit of a mixed bag, so let’s break it down.

Right now, the water temp is ticking along pretty average for this time of year, so no wetsuit drama there.

The first surf worth paddling out for lands on Friday morning, 28 August. The swell is a solid 6 ft out of the east with a period of 9 seconds. The combined energy is moderate at 997, so there’s some grunt. Winds are light from the NE—cross, so it’s a bit raggedy. This is a marginal call, but it’s the first bit of action, and the tide might be a factor, so take it as an early morning gamble if you’re keen.

Saturday morning, 29 August, is where things clean up nicely. Swell holds around 6 ft from the east, period bumps to 10 seconds, and the wind shifts north at 9 mph, blowing cross-offshore. The water gets clean, and the energy is still decent at 827. This is your best bet of the first week—clean, friendly, and the crowds will be around sometimes, but it’s worth it.

After that, the surf takes a nosedive. Sunday through the end of the first week, we see small, weak, choppy waves and poor conditions. There’s a gap of about four to five days with nothing really worth recommending. The swell drops to under 3 ft, periods are short, and the wind is messy.

There’s a bit of a pick-up around Wednesday morning, 2 September, with 4 ft from the east and a strong cross-off wind from the WSW at 22 mph—clean but still only moderate energy (490). The swell is a bit short-period and the quality rating doesn’t match the wind conditions, so it’s not a standout. Thursday, 3 September, gets a pulse of southerly swell at 5 ft with a long period of 14 seconds (energy 1094), but the wind is cross-onshore and lumpy, so it’s not inviting.

Now, the big one that will get your heart pumping is Saturday morning, 5 September. We’ve got a massive 16 ft easterly swell, period 12 seconds, and a staggering combined energy of 6979. Winds are NE at 22 mph—cross, so it’s lumpy. The swell is predicted to be too big for this break, so unless you’re an expert and looking for a mission, this is more for the tow crew. The afternoon cleans up slightly with a light cross-off, but at 15 ft, it’s still very large.

Sunday morning, 6 September, drops to 8 ft from the east, period 11 seconds, with a gentle cross breeze—marginal but rideable for strong intermediates. Things then taper off into smaller, cleaner but weaker surf for the rest of the week.

The standout of the entire outlook is Saturday morning, 29 August. That’s your clean, manageable, fun session. If you’re a more experienced surfer and want a big challenge, keep an eye on 5 September—but that’s only for experts.

Overall, there are a few days where conditions line up, but it’s not a classic run. The first week gives you one good morning, and the second week is either too big or too weak for consistent quality. Stay patient.

Rusty.
