The Lowdown
Alright, Rusty here, breaking down the Yonabaru forecast.
It’s a rough start, no two ways about it. For the first few days, the surf is practically non-existent. The water is warm, about average for the season, so at least the temperature is nice.
From Wednesday morning, July 29th, through to Sunday, August 2nd, the waves are barely a ripple. Heights are under 0.5 feet, the combined swell energy is weak (reading 30, 20, 22), and the winds are glassy. It’s pretty out there, but there’s no surf to speak of. We’re looking at a 4-day stretch of flatness.
Things get a little more interesting on Monday, August 3rd. The swell builds to 3 to 4 feet from the ESE with a very long period of 16 seconds. That brings the energy up to 532 and then 803 (moderate). The wind is a clean cross-offshore from the NNW, so the surface will be smooth. It’s still just a marginal, beginner-friendly option, but at least you can get wet.
Tuesday, August 4th, the swell pushes higher, to 5 to 6 feet from the ESE, with a period of 17-18 seconds. The energy is strong now, at 1633 and 1995. But the wind goes cross-shore from the north, which will put a bit of chop on the face.
The one true standout is the morning of Thursday, August 6th. The swell is a solid 11 to 12 feet from the east, with a very long 18-second period. The combined energy is massive at 8015. The wind is a clean cross-offshore from the NNW. This is big, powerful stuff. That 11-foot-plus swell is strictly for experts only. The long period might make it a bit straight at the beach, but for the crew who can handle it, it’s a big morning. The afternoon sees the wind stiffen up and the swell drop, so you need to be there early.
After that, it falls apart. Friday, August 7th, is a total loss with storm-force winds making it impossible to paddle. The rest of the forecast is a mess of strong cross-shore winds and onshore junk, with the swell being too big or too ugly. August 11th sees another 11-foot pulse, but the wind is onshore, so it’s no good.
So, if you’re a hardcore surfer, the only real window is the morning of Thursday, August 6th. Otherwise, it’s a long wait.
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.
