Yonabaru Surf Forecast and Surf Report

Alright, let’s talk about what’s coming up for Yonabaru. Right now, it’s flat. I mean, really flat. For the next few days, we’re looking at tiny little dribblers—knee-high at best, and the wind’s mostly onshore or side-shore. Not worth paddling out. The swell energy is barely registering (35 to 19, just weak numbers). You’ll be bobbing around on a paddleboard, not surfing. That stretch from Tuesday the 28th of July right through to Sunday the 2nd of August is a total write-off. Don’t bother.

Then things start to change. On Sunday afternoon, we finally see a pulse of long-period energy (16 seconds) come in, but it’s still only 1 ft and the combined energy jumps to 86—still weak, but a sign of life. Monday the 3rd of August is where it gets interesting. Morning and afternoon both show 3 ft of swell out of the ESE with a 14-second period, and the energy is moderate at 371. The wind is cross-offshore, clean. That’s the first real window. It’s small but clean, and for a beginner-friendly break like Yonabaru (fairly consistent, sometimes crowded), that’s a nice little session. The water temp is about average for this time of year.

Tuesday the 4th of August brings a bigger jump: 4 ft to 5 ft by the afternoon, with an 18-second period from the ESE. That’s a long-period groundswell, and the energy climbs to strong levels (948, then 1500). The wind turns cross-shore and stronger in the afternoon, so the morning looks cleaner. At 5 ft, it’s still okay for intermediates, but the long period means it might wall up a bit at this beach break—could be a bit tricky with the sets.

The standout window looks to be Wednesday the 5th of August through Thursday the 6th. On Wednesday, we get 7 ft to 7 ft of east swell with an 18–19 second period, energy in the strong range (2854–3577). The wind is cross-offshore and clean. That's solid, powerful surf. Thursday morning hits 10 ft with 18 seconds and energy at 6879—that’s very strong. By Thursday afternoon it’s 12 ft, same direction, energy at 7387. But here’s the thing: the file says that swell is predicted to be too big for this break. For a beginner spot, 12 ft with that kind of power is expert-only, and even then, the 19-second period means it’ll be a freight train. Only go out if you really know what you’re doing.

After that, Friday the 7th of August still has good size (8 ft morning, 5 ft afternoon) but the wind cranks to 19 mph offshore—fresh, clean, but strong. The swell shifts to ENE. Energy stays strong (3452 morning, 1326 afternoon). Saturday the 8th of August is a real surprise: the swell direction swings to NNE, size around 6–6 ft, period 13 seconds, and the wind goes light and variable, glassy by afternoon. Combined energy is moderate to strong (1461 to 1177). That’s a beautiful window for experienced surfers—clean, glassy, and not as intimidating as the earlier giant stuff.

Then from Sunday the 9th onward, it all falls apart again. Onshore winds, dropping swell, poor conditions. A few days of nothing until the middle of the month, but nothing worth chasing.

So, the best bets: Monday the 3rd of August for a clean, small session if you’re learning or want a longboard. But the real standout is Saturday the 8th of August—glassy conditions, solid 6 ft to 6 ft swell from the NNE, and a nice 13-second period. That’s the one to circle on the calendar. Just keep in mind it’s more than a week out, so things could shift.

Stay stoked.
