Yonabaru Surf Forecast and Surf Report

Alright, Rusty here. Let’s have a look at this one.

Right off the bat, I gotta be straight with you. It’s gonna be a slow start. Real slow. For the first week or so, from Sunday the 16th right through to the 23rd, there’s virtually nothing worth paddling out for. The swell is tiny – we’re talking ankle-biters at best – and the wind is mostly onshore or cross-onshore, which just messes up what little bump there is. There’s a few days of cross-offshore breezes around the 21st and 22nd, but with wave heights barely hitting 1 ft and weak energy readings, it’s just flat and frustrating. You’d be better off getting the wax off your board for a while. This is a proper gap in the action.

Now, hang in there, because it starts to turn around. On Monday the 24th, things finally get interesting at Yonabaru. We get a pulse of swell arriving from the ESE at about 3 ft, but the key here is the period – it jumps to a long 13 seconds. This is groundswell energy, and it brings shape. The morning is glassy, and by the afternoon the wind swings offshore from the west. We’re talking clean lined-up waves. It’s not huge, but it’s the first real surf we’ve seen.

Tuesday the 25th is when you want to be in the water. The swell picks up to a solid 4 ft from the ESE with that same long 14-second period, and the wind is clean offshore from the WNW all day. The wave energy is boosting up nicely. The morning is particularly sweet. For a beach break, this kind of long-period groundswell can run a bit straight, but with offshore wind and that energy, Yonabaru should be offering up some nice, workable walls. It’s still manageable for intermediate surfers, and the conditions are top-notch.

Wednesday the 26th and Thursday the 27th keep the goods coming. Wave heights hold around 4 ft to 5 ft, still from the ESE with that lovely 14-second interval. The wind stays in a favourable cross-offshore to gentle offshore direction. By Thursday afternoon, the energy is pumping hard. It’s solid, clean surf day after day.

But the real standout – the one you should mark on the calendar – is Friday the 28th of August. The swell bumps up to a proper 7 ft from the east, with a very long 15-second period. That’s a serious groundswell. Now, this is a bigger size. For beginners, 7 ft is pushing the limits. But for anyone with a bit of experience, this is where it gets epic. The afternoon is looking glassy, with barely a breath of wind from the WNW. The energy is off the charts. For a spot like Yonabaru, which is fairly exposed and a beach setup, that long-period east swell and glassy conditions could produce some absolutely beautiful, powerful waves. It won’t be the easiest paddle, but the quality will be unreal. This is the session to plan for.

After that, the wind turns onshore again on Saturday the 29th, and the swell fades fast. By Sunday the 30th and Monday the 31st, we’re back to small, bumpy surf. It’s a short-lived window of excellence, but what a window.

The water temperature? It’s about average for this time of year around Yonabaru, so no surprises in the water temp.

To sum it up: you’ve got a flat start, then a golden run from the 24th to the 28th, with Friday the 28th being the absolute best. Don’t miss it.
