Table - best surf conditions forecast for Yonabaru over the next 16 days.
Alright, Rusty here. Let's take a look at what's on offer at Yonabaru.
Honestly, it's a tough stretch of days ahead. The whole 16-day window is a bit of a write-off for decent paddle surfing. There's a lot of wind and not much quality on the table. The water is a warm 85°, which is about average for the time of year, so at least you won't be cold while you're getting blown off your board.
The first week is a complete mess. Starting Thursday the 9th, we've got a massive 15ft SE swell, but it's accompanied by a fresh onshore breeze and the risk of thunderstorms. The wave energy is severe (12477), but it's just too big and messy to be any fun. The next day, Friday the 10th, is even worse. We're looking at a huge 30ft SE swell with near gale-force onshore winds at 31 mph. That's a hard pass for anyone – it's a recipe for a beating. The wind just gets stronger into Saturday the 11th and Sunday the 12th, with gale and near gale-force cross-onshore winds keeping the ocean completely blown out. There's nothing to paddle into here.
We get a bit of a lull from Monday the 13th through to the middle of the week, but it's tiny, with weak, short-period swell barely reaching 1.0ft. The winds are mostly cross-shore or cross-onshore, creating a lumpy, choppy mess. The energy is in the single digits (14 to 21), so there's just no power in the water. It's not worth the effort.
The second week offers a slight glimmer, but it's still not great. On Saturday the 18th, the swell picks up to 5ft from the ESE, with moderate onshore wind. The energy is moderate (481), but the conditions are still poor. By Monday the 20th, we see a 7ft SE swell with a gentle cross-shore breeze, which is the best wind we've seen in a while. The energy is strong (769), but the forecast says it's marginal. The period is a short 9 seconds, so it'll be a bit weak and close-outy. The last day with any real hope is Thursday the 23rd. We have a 3ft E swell with a light cross-offshore breeze from the NNW, giving us clean conditions for the first time. The energy is a low 122, but it's the cleanest surf of the entire run.
The standout, if you can call it that, is Thursday the 23rd at Yonabaru. With a 3ft swell from the east and a light cross-offshore wind, it’ll be the cleanest you'll see. It's not big, but it's the only time the stars align for a bit of a smooth surface. Don't expect much power, but it’s your best bet for a few grovelly ones.
Honestly, for a spot that's fairly consistent, this is a long stretch of poor conditions. For the most part, the setup looks more interesting for a kite surfer than a paddle surfer, given the strong onshore wind and sizeable swell in the first week. Keep an eye on the forecasts, because it tends not to stay this poor for long.

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.
