The Lowdown

Alright, Rusty here. Let's be straight with you—honesty's the only way to go. Looking at the full 16-day window for Yonabaru, it's a pretty grim run. The forecast keeps throwing up "poor surf conditions" over and over again. We've got some size at times, but the wind and swell direction just aren't lining up to give us anything clean and rideable. This stretch is going to test your patience.

The only break on the radar is Yonabaru itself. Water temp's sitting at 84°, which is about average for this time of year, so at least you won't be freezing while you're waiting for a wave that never comes. The first few days are the biggest letdown because there's actually some swell around. On Sunday the 6th, we've got a 8ft northerly swell pushing in, with a combined energy of 615 (moderate to strong), but a nasty 22 mph crosswind from the north is going to turn it into lumpy chop. Not worth paddling out for. That carries into Monday the 7th and Tuesday the 8th—swell drops a bit to 5ft–6ft, but the wind swings offshore from the NNW at 16–19 mph, giving us cleaner conditions. Still, the scores say these are marginal at best, with questionable tide or just not enough push.

From Wednesday the 9th onward, the wind turns onshore or cross-onshore, and the swell direction goes all over the place—north, east, southeast. Nothing lines up right. You'll see a spike on Friday the 11th with a 6ft easterly swell and combined energy of 454 (moderate), but it's onshore and messy. The whole stretch from the 9th right through to the 20th is a write-off, with no recommendations at all. That's a solid 12-day gap of poor surf. The energy levels vary—some days are weak (96 on Thursday the 10th), others are strong (795 on Saturday the 12th)—but it doesn't matter because the conditions are always wrong.

The only thing that might raise an eyebrow is Friday the 18th. We've got a 10ft southeasterly swell rolling in, with combined energy shooting up to 1207 (very strong). But that's a big, powerful swell with a short period of 8 seconds, and the wind is onshore from the ESE at 12 mph. For a beach setup like Yonabaru, that's going to be a washing machine. At that size, it's expert-only territory, and with the onshore wind, it's honestly looking more like a day for the kite crew than paddle surfers.

So yeah, there's nothing to get excited about here. The surf just isn't on. Yonabaru's a beginner-friendly, fairly consistent spot when the conditions are right, but this forecast has no standout windows. Sometimes the ocean just says "not today," and that's how it goes. Forecasts can change, but right now? I'd leave the board at home.

Rusty.

Information about the Yonabaru Surf forecast

The above surf forecast table for Yonabaru provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Yonabaru can be found by selecting the local surf guide option on the grey menu. Our Yonabaru surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Yonabaru) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).

Further information to help with frequently asked questions about our surf forecast for Yonabaru may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.

Yonabaru is 5 km (3 miles) from the city of Ginowan. If you plan a holiday in Okinawa, look for hotels and other accommodation in Ginowan. Ginowan has rooms for a wide range of budgets as well as car hire and transport links.
