Table - best surf conditions forecast for Yonabaru over the next 16 days.
Hey, Rusty here. Let's break down what's coming for Yonabaru. It's gonna be a slow burn, so don't rush it.
We've got a rough opening. Starting Wednesday, July 8th, there's a big 8ft swell from the SE, but the wind is onshore and junk. The water's about 84°F, which is pretty normal for this time of year. The combined wave energy is a huge 3059 but it's all noise. This slop carries on through a stormy weekend and into the next week. There's a big gap where there's just nothing worth paddling for. The swell is tiny and the wind stays messy.
Your first real chance comes on Monday, July 20th. The morning is still a bit cross-shore, with a 5ft swell from the ENE and a 10-second period. But Monday afternoon is where it's at. The wind swings light cross-offshore, the same 5ft swell is pumping with 586 in combined energy, and the surf cleans up nicely. That's your session to aim for.
Then on Tuesday, July 21st, we get another golden hour. Tuesday afternoon sees a smaller 3ft east swell, still with a nice 10-second period, and the wind goes glassy. Dead flat calm. Moderate energy at 167, but with those clean, peelable conditions, you'll be stoked. For a beginner-friendly spot like Yonabaru, that’s as good as it gets.
Bottom line: sit out the first ten days of junk. Your best bets are Monday afternoon the 20th and Tuesday afternoon the 21st. That's where the clean surf is hiding.
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.
