Yonabaru Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s have a look at what’s on the cards for Yonabaru. Straight up, I gotta be honest with you—this isn’t a pretty picture. The entire 16-day window is looking grim, and we’ve got a long, dry spell ahead. There’s not a single good session to recommend, so we’re in for a real test of patience.

The trouble starts now and doesn’t let up. The first few days are a write-off. From Monday the 31st of August right through to the end of the first week, we’ve got messy, onshore winds and poor surf conditions. The wind is blowing hard from the east and southeast, mostly onshore or cross-onshore, chopping everything up. Swell heights bounce around between 1ft and 8ft, but the quality is just not there. The combined wave energy hits moderate levels—like 460 on Monday afternoon—but it’s all for nothing with that wind.

Tuesday the 1st of September sees the swell bump up to 8ft from the ESE, with energy pushing into the strong range at 1034, but again, it’s blown out by a moderate breeze and risk of thunderstorms. Not a chance.

We then hit a real flat spot through the middle of the week. Thursday the 3rd and Friday the 4th are tiny, with swell dropping to 1ft to 3ft and weak energy readings as low as 38. Honestly, it’s more like a lake than the ocean.

The weekend of the 5th and 6th is still small and weak, with energy in the double digits (68 to 104). The wind is still a problem. Then, around Monday the 7th of September, we see a glimmer of something bigger. The swell period jumps to 14 seconds and the energy rockets to 1253 on Monday afternoon, with 5ft from the E. But the wind is cross-onshore from the NE at 16 mph, ruining any chance of clean surf.

From Tuesday the 8th through to Thursday the 10th, the swell gets serious—10ft to 10ft from the East, with periods of 10 to 12 seconds. The energy is very strong, reading between 1822 and 2739. But this is a classic case of “so much swell, so little quality.” The wind is still cross-onshore and fresh, making it lumpy and messy. At 10ft, this is only for the experts, and even they’ll be fighting the chop. The combined energy is massive (1850 to 2739), but it’s a raw, unrefined power. For a beach break like Yonabaru, this setup looks more interesting for kite surfing than paddle surfing.

Friday the 11th shows a slight improvement as the wind eases to a gentle breeze, and the swell drops to 7ft from the E with an 11-second period (energy 1055). Conditions are still just marginal, with a cross-shore that might offer a few clean-ish waves if you’re desperate, but it’s not a standout.

The final weekend, the 12th and 13th, reverts back to poor form. Swell jumps again on Sunday the 13th to 13ft from the ESE, with energy over 3000, but it’s all onshore wind. That’s a washing machine, not a surf session.

The last day in the data, Tuesday the 15th of September, has a 5ft groundswell from the ESE with a very long 14-second period and energy of 1303, but the wind is a fresh 19 mph cross-onshore. Again, just lumpy and unrideable.

So, bottom line: there’s nothing to recommend here. The best you could say is that the swell window is active, and the longer-period swells (11 to 14 seconds) suggest energy, but the wind never plays ball. It’s a blank run, and for this area, that’s not unusual when the trades lock in. We’ll have to wait for the next system to shift the wind. Keep checking in, because forecasts can change.

Stay patient, stay salty.

Rusty.
