The Lowdown
Alright folks, Rusty here. Let me be straight with you—the next couple of weeks are looking pretty grim for a real surf at Yonabaru. The swell window just isn't lining up, and we have a whole lot of nothing on the horizon for a while. I'm looking at a blank stretch that runs from now practically all the way through to the middle of next week. It ain't pretty, but that's how it goes sometimes.
The only glimmer of hope is right at the start, and even that's a shaky one. Thursday morning (September 3rd) we've got some east swell pushing in at 8ft, but it's a jumbled mess with a short 10-second period and the wind is all over the shop, coming cross-shore. The water's a warm 84°F, which is dead on average for this time of year, but that's about all it has going for it. It's got a bit of energy behind it (1255), but the conditions are marginal at best and there's a risk of thunderstorms. With that size, it's already pushing past what the beginners should be looking at anyway.
The rest of the first week is a write-off. Waves drop right off into the 2-3ft range and stay there for days. We're seeing a lot of clean-looking forecasts, but with nothing to push it, it's just flat and gutless.
We don't see anything remotely rideable until the 15th of September, a Tuesday. Even then, it's a marginal 3ft with a long 12-second period, but the wind is cross-shore and it's a "questionable tide" call. Not exactly something to get amped about. That longer period does mean it'll have a bit more shape, but a point break like Yonabaru might see it breaking a little too straight. It's a step in the right direction, but it's a long way from a standout.
To be honest, the only thing that gets any real energy behind it (305) is that Tuesday afternoon, but the swell direction is still east, which isn't the juice this spot really wants (that would be NE). The whole window is just a poor match for the coast.
So, we're looking at a long, quiet spell. It's frustrating, but the forecast can always shift. Hang tight, check back in a few days. If there's one thing I've learned, it's that the ocean always has a way of surprising you. Keep the boards waxed anyway.
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.
