Table - best surf conditions forecast for Yonabaru over the next 16 days.
Alright, Rusty here. Let's have a look at what's on the table for the next couple of weeks, and I gotta tell you, it's a bit of a rough stretch to start. We're looking at a long, quiet spell before things finally wake up.
The next few days are pretty much flat. There's just nothing going on. From now until Saturday the 27th of July, it's a grim run of tiny, weak, and mostly messy conditions. You'll see waves around 0.7 ft to 1 ft, but the energy is almost non-existent, and winds are mostly cross, cross-off, or even onshore, so don't bother paddling out. That's a solid two-week gap with nothing worthwhile.
Then things finally change. The standout window kicks off on Monday the 27th of July. We get a pulse of proper swell at Yonabaru, and it's the only real highlight of the whole 16-day run. The swell jumps to a clean 5 ft from the SE with a period of 10-11 seconds. That kind of period is solid, meaning good shaped waves with real push behind them. The wave energy jumps massively (466 and 431), telling you it's got some serious grunt for a spot that's been asleep.
Now, the wind on Monday is onshore from the East at 9 mph, so it won't be glassy. But for this area, given the long wait, a 5 ft SE swell is a proper event. Tuesday the 28th of July is still worth a look, with swell dropping but still at 4 ft, though winds are more cross-onshore and a bit choppier. Monday is your day.
To sum it up: chalk the first two weeks off. Then, on Monday the 27th, get ready for a real pulse at Yonabaru. It's the only big move in the forecast, and while it won't be picture-perfect due to the onshore flow, it's the best surf you'll see in this outlook. For beginners, that 5 ft might be a step up, so be cautious.
Signing off,
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.
