The Lowdown

Alright folks, Rusty here. Let’s get straight into it. We’re looking at a pretty grim picture for the next couple of weeks around Yonabaru. To be honest, there’s just nothing worth paddling out for until the very end of the run, and even that is a big question mark.

Right now, we’re dealing with a wild setup. The first few days are a write-off. Friday the 7th has a massive 47 mph westerly gale blowing, with a 6 ft swell from the north-northeast, but the wind is so strong it’s just ridiculous. The combined energy is a chunky 1293, but you’d be a fool to go out. It’s a severe gale and it’s offshore here, but that’s not a good thing – it’s just dangerous. The water is 86°, which is a touch warmer than normal for this time of year.

From Saturday the 8th all the way through to Thursday the 21st of August, it’s just a long, sad run of poor surf. The wind is almost always cross-shore, onshore, or just messy, and the swell is tiny. On Saturday the 8th we’ve got 2 ft to 3 ft from the east with gale-force cross-shore winds – absolute junk. Sunday the 9th and Monday the 10th are just as bad with strong cross-shore breezes and lumpy chop. The combined energy on the 10th hits 363, but it’s a 14-second period groundswell which is actually too long for this beach break setup – it’ll just close out straight.

There’s a brief glimmer on Wednesday the 12th, with a clean, gentle offshore wind and a 2 ft swell from the east. The combined energy is only 88, so it’s weak, but it’s the only time in the whole forecast where the waves are described as "surfable". Still, 2 ft on a beginner-friendly break with a clean wind is about as small as it gets. It’s a long way from good.

The pattern then returns to onshore slop. From Thursday the 13th through to the 22nd, it’s almost all onshore wind, small swell, and poor conditions. You’ll see the odd bump in energy – like on the 21st with a 5 ft south-easterly swell and combined energy of 319 – but the period is a short 8 seconds and the wind is a fresh onshore. It’s just messy close-out surf.

The only real standout, if you can call it that, is a gentle, clean window on Wednesday the 12th. It’s not going to be anything special, but if you’re desperate for a paddle and a few small, clean waves, that’s your moment. The rest of the 16 days is a full-on blank. Forecasts can change, but right now, this is a tough stretch for Yonabaru.

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.
