Yonabaru Surf Forecast and Surf Report

Right, let’s have a look at this one, Yonabaru. It’s a bit of a beast this stretch, to be honest. The setup is a beginner-friendly break that’s fairly exposed, and it likes a NE swell direction. The water temp is sitting right on 84°F, which is pretty much normal for this time of year – nothing out of the ordinary there.

Now, straight up: the surf’s tricky over the next 16 days. We’ve got a huge block of ‘poor surf conditions’ running for most of it, so don’t get too excited too fast. But there are a couple of very intense windows that will demand respect, though only from the right crew.

Looking at the first real shot: Tuesday, 25th August. The swell comes out of the gate swinging. We’re talking a 15 ft swell from the ESE with a very long period of 17 seconds – that’s a proper groundswell. The combined wave energy is absolutely monstrous at 11175, which is some serious power. The wind’s a cross-shore from the north at 16 mph morning, then cleaning up to a cross-offshore NNW breeze in the afternoon at 22 mph. But here’s the big catch: this is simply too much size for Yonabaru. The numbers say it’s going to be blown out and way over the head, maybe even dangerous. The tide and wind are favourable, but only if you’re an absolute expert. For anyone else, give it a miss. The afternoon looks a touch cleaner, but at 15 ft and that massive energy, it’s still a big, heavy ocean. The long period (16-17 seconds) means these waves will have a lot of grunt, they’ll be better shaped, with longer lulls between sets – but for a beach break like Yonabaru, a period that long can make it break straight and close out. Basically, this day is a standout for power, but not for a fun, mellow surf.

Then things go quiet for a long stretch. Wednesday the 26th through to Monday the 7th of September is pretty much a write-off – mostly poor conditions, tiny waves, or a mess. It’s a solid 10+ day gap with nothing worth paddling for.

The second interesting blip hits hard on Wednesday, 2nd September. This is another huge swell event. Morning brings an 18 ft ESE swell at 12 seconds with cross-offshore wind from the WNW at near-gale force (37 mph!). That wind will carve the faces, but it also means the energy is through the roof at 9285. By the afternoon, it gets even bigger – 21 ft SE swell, with the same long period of 12 seconds, and the wind goes full offshore from the WNW at 31 mph. The combined energy is 12451 – an absolute beast. The conditions are clean and the tide is supposed to be okay, but honestly, 21 ft at a beginner spot is a no-go for 99% of surfers. This is expert-only territory, and even then, paddling out in a near-gale offshore wind will be a mission. That’s the raw power you’d expect, but the risk is off the charts.

After that, Thursday the 3rd and Friday the 4th of September fade into tiny, clean but almost flat conditions, with a little 2 ft to 2 ft swell from the east. The wind goes offshore and light, which would be beautiful, but there’s just no water moving. The 4th afternoon is almost surfable – just “ordinary” – with that gentle 9 mph offshore breeze and a tiny 2 ft wave. It’s the cleanest the whole window gets, but the size is pathetic.

The last few days (6th through 9th September) are mostly poor, with small onshore junk from the east. Nothing to write home about.

To be honest, the only standout here is Tuesday, 25th August for the raw, heavy power, and Wednesday, 2nd September for the extreme, expert-level swell. But neither is a good bet for a relaxing session at Yonabaru. It’s too big and too gnarly for this break. The rest is a long, flat, and messy desert. If you’re a beginner or even intermediate, you’re better off doing something else for the next two weeks.

Stay safe out there.
