Yonabaru Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s take a look at what’s shaping up for Yonabaru over the next couple of weeks.

The water temp is sitting at 87°F which is a touch warmer than normal for this time of year, so you’ll be in for a balmy session if you get in.

We’re looking at a slow start. Saturday afternoon kicks off with tiny 1ft swell from the SE, cross-off NW wind, but it’s tiny and the energy is weak (23) – really just a paddle. Sunday morning is more of the same, but by Sunday afternoon we start to see a pulse: 2ft from the ESE with a 17-second period, clean cross-off wind, and energy climbing to 186. That’s small but with that long period, Yonabaru might offer a few nuggets.

Monday morning the swell builds to 3ft (ESE, 15-second period, energy 403) but winds are cross. Still, it’s surfable. Monday afternoon pushes to 4ft (energy 636) – still cross, but the size is coming up. Tuesday morning hits 5ft from the ESE, 18-second period, energy 1288, still cross-shore winds. The waves are getting some push now, but the quality is being held back by that wind direction. Tuesday afternoon we see 6ft from the E, 18-second period, energy 1789, with a risk of thunderstorms and still cross winds.

Now, Wednesday morning (5th August) is where things get real: 8ft from the E, 18-second period, energy 3957. This is getting into expert territory – too big for beginners. Wednesday afternoon jumps to 10ft, but the wind goes cross-on and it gets messy. Thursday and Friday (6th and 7th August) see the swell absolutely hammering the coast: 18ft to 21ft from the E, with winds screaming from the north at 28–65 mph. Energy readings are massive (19,773 to 42,594). The break is predicted to be too big even for this spot, and with those winds, it’s a dangerous mess. This is more a kite-surfing setup than a paddle-surfing one.

After that, things drop off fast. From Saturday 8th August through to the end of the period, the swell is tiny (0.7ft to 3ft), winds are mostly onshore or cross-off from the south, and the energy is low (under 500). The standouts in this second week are hard to find. There’s a brief window on Wednesday 12th August afternoon: 3ft from the E, 12-second period, energy 284, with clean cross-off winds from the SSW. That’s the pick of the second week, but it’s still small. Thursday 13th August morning offers glassy conditions with 3ft from the E, 11-second period, energy 173 – but again, it’s marginal.

If I’m calling the best on offer, it’s Tuesday afternoon (4th August): 6ft from the E, 18-second period, energy 1789, with light cross winds from the NNE. That’s the most size and energy before the huge stuff arrives, and the wind is still manageable. The long-period groundswell (18 seconds) will give it good shape, but at a beach break like Yonabaru, it might be a bit straight – still, the best of the run.

Overall, the first week has a clear window of building swell from Sunday afternoon through Tuesday, with the standout being Tuesday afternoon. After that, it’s either too big and windy, or too small. The second week is pretty quiet.
