The Lowdown
G’day, I’m Rusty. Gonna be honest with you, this 16-day run for Yonabaru is a tough one. We’re looking at a long stretch of pretty much nothing worth paddling out for, and then a really wild, short spike that’s only for the brave. The first good chance to get wet doesn’t hit until Monday the 28th of July, and even then it’s a serious situation.
From now through the weekend of the 26th, it’s all flat and messy. Tiny waves, mostly around 1ft, with a bit of a push from the east. The wind is mostly cross-off or light, so the water might look clean, but there’s just no energy. The combined energy is weak, barely hitting 30 to 40. Honestly, it’s a write-off for a solid week. You’re better off leaving the board in the car.
Then things get weird. On Monday the 28th, a big pulse of groundswell arrives from the southeast. The swell height jumps to 8ft on the morning of the 27th, but the wind is rough and onshore, so it’s just a messy, choppy mess. The real standout is the next day, Tuesday the 28th of July. The swell peaks at a massive 26ft from the southeast, with a very long period of 15 seconds. The combined energy is absolutely pumping at 40184. That’s a lot of water moving.
But here’s the catch, mates. This is way too big for anyone but the most experienced big-wave chargers. The wind is a fresh cross-onshore, and the swell is so powerful that it’s going to be a dangerous, washing-machine kind of day. For a beginner, this is a definite no-go. For the experts, it’s on, but it’s a serious mission. The swell direction is from the southeast, which isn’t ideal for Yonabaru’s optimum northeast exposure, so the quality might be a bit lined up and straight.
The rest of the month after that big day fades fast. By Wednesday the 29th, it’s back to near flat, with tiny leftover energy. The water temperature is about average for this time of year, nothing to write home about.
So, the only true standout, and it’s a big one, is Tuesday the 28th of July at Yonabaru. If you’re a pro and you’ve got the right equipment, that’s your window. For everyone else, it’s a long wait. The surf is a no-go for about a week and a half, then one dangerous day, and then flat again. Keep an eye on the forecasts, but this one’s a tough pill to swallow.
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.
