Yonabaru Surf Forecast and Surf Report

Alright, let’s talk about Yonabaru. This is a beginner-friendly spot, fairly consistent, and it’s fairly exposed to swell, with an optimum direction out of the northeast. Right now, there’s nothing to get excited about for a while. The first real stand-out doesn’t show up until Tuesday the 25th, so you’re looking at a gap of a couple days of pretty poor conditions before that.

Tuesday morning the 25th, we get a big pulse of swell from the ESE, pushing 13ft with a solid 17-second period. That’s a long-period groundswell, proper energy. The combined wave energy is very strong (9414). Winds are going to be from the NNW at 16 mph, which is cross-offshore, so the face should be pretty clean. The swell size is well over 8ft though, so this is expert-only territory. Water temp is 84°, which is normal for the time of year. Tuesday afternoon the swell holds around 15ft with similar conditions, winds picking up a bit to 22 mph, still cross-off. This is the best window in the whole outlook, but only for very experienced surfers.

Wednesday the 26th takes a turn. Morning has a near gale from the WSW at 34 mph, offshore but nearly impossible to paddle into. The swell drops to 8ft from the NNW, with moderate energy (2026). Afternoon gets messy with rain and strong wind, tiny 1ft swell.

From Thursday the 27th all the way through to Monday the 2nd of September, it’s mostly small, weak, and choppy. Swell heights bounce between 1.0ft and 7ft, but the wind is almost always cross-onshore or onshore, and the wave energy is weak to moderate. Not worth paddling out.

Then Tuesday the 3rd of September morning brings another big pulse: 12ft from the ESE with a 12-second period and strong energy (3662). Winds are from the north at 19 mph, cross-shore, and the forecast says wind and tide are favorable, but it’s too big for this break. Again, expert-only territory.

Wednesday the 4th of September morning offers a slight improvement: 6ft from the east, 11-second period, with a light cross-offshore breeze from the NW at 12 mph. The wave energy is moderate (1349). It’s still considered marginal surf, but it’s the most approachable day for a stronger surfer. Afternoon has 7ft from the NNW, 9-second period, with lighter 9 mph offshore winds, cleaner but still marginal.

After that, from Friday the 5th through the end of the outlook, it fades back into small, weak, and choppy conditions with onshore or cross-onshore winds. Nothing worth chasing.

So, for a beginner or even intermediate surfer, Yonabaru is a tough call in this 16-day window. The one standout is Tuesday the 25th, but it’s a beast of a day. Beyond that, the second week gets a little better around the 4th of September, but it’s still not great. Keep an eye on the forecasts, because when it’s right, this spot can be fun.
