Yonabaru Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s have a look at what’s cookin’ for this stretch of coast.

Right off the bat, we’re looking at a pretty grim run of surf. The first few days are almost non-existent. The swell is tiny, and the wind is all over the shop. We’re talking about a real dry spell. Things don’t start to get interesting until Monday, August 2nd, when we see a bit of life in the water. The ESE swell builds to 2ft with a very long period of 17 seconds, and the combined energy jumps to 188 (moderate). That’s a taste of the groundswell to come, but the wind is still cross-off, so it’s not all bad. But honestly, it’s still pretty ordinary.

The first real standout is shaping up for Monday, August 3rd, and the morning is the pick. The swell is up to 3ft from the ESE (15-second period), with combined energy now at 487 (moderate). The wind is a clean cross-off from the NNW, so the waves should have some shape. The water’s a touch warmer than normal at 86°, so the conditions are about as good as it gets for a beginner-friendly break like Yonabaru. The crowd profile says “sometimes,” so you might have to share the peak, but it won’t be a zoo.

As we head into Tuesday, August 4th, the swell jumps again. The morning offers 5ft from the ESE (18-second period, very long period groundswell). The combined energy is a solid 1480 (strong). The wind is light and cross-shore. This is a good setup for Yonabaru, but with that long period, the waves might be a bit too straight for the beach break. Still, it’s the best window of the week. The afternoon sees the wind shift to a cross-on, which will mess up the faces a bit.

Now, the big news is Wednesday, August 5th. The swell is hitting 12ft from the E (18-second period) in the afternoon, with a massive combined energy of 7236 (very strong). That’s serious power. The wind is cross-shore, but the numbers are screaming “too big for this break.” This is expert-only territory. The forecast says the wind and tide are favorable, but the swell is too big. If you’re a pro, maybe. But for mere mortals? It’s a no-go.

Into Thursday, August 6th, the swell is even bigger – 21ft (19-second period, very long period) with a combined energy of 34651 (very strong). The wind is a near gale, cross-shore with crossing waves. This is a dangerous mess. Totally unsurfable for anyone.

From Friday, August 7th, through the rest of the outlook, it’s a complete write-off. The wind is a violent storm or hurricane-force, and the swell is either tiny or chaotic. The combined energy drops to 44 (weak) or less. The surf is just a total washout, with poor conditions and dangerous winds. The last real chance for a wave is on Sunday, August 16th, where the swell is 4ft from the E (14-second period) with a combined energy of 492 (moderate). The wind is light and onshore, so it’s marginal. Not something to get excited about.

So, to sum it up: the best bet is the morning of Monday, August 3rd, at Yonabaru. Clean, 3ft ESE swell, cross-off wind. It’s the only truly decent surf in the whole 16-day window. The rest is either too small, too blown out, or too dangerous. Don’t plan a trip around this one.

Rusty.
