The Lowdown
Alright, Rusty here. Let’s break down what’s coming.
The start is a real bummer. From Thursday the 23rd of July all the way through Sunday the 2nd of August, there’s next to nothing. Swell is tiny, barely 0.4m at best, periods are short around 9-10 seconds, and the wave energy is super low – mostly in the teens and twenties. Wind is onshore or cross-onshore almost the whole time, making it choppy and messy. No point suiting up. A dry spell like this is pretty normal for Yonabaru when the stars don’t align.
Finally, Monday the 3rd of August shows some pulse. Swell hits 0.9-1.1m from the ESE with a 16-second period – that’s long-period groundswell – and energy jumps to 432-636. Light cross winds keep it rideable, but it’s still only marginal.
The real gem is Tuesday the 4th of August. Yonabaru gets 1.6m swell from the east with a killer 17-second period, and energy maxes out at 1543 – strong stuff. Wind goes glassy calm in the afternoon. That means clean, powerful lines. The east swell lines up well with the optimum direction, so waves should wrap in nicely. At 1.6m with that period, it’s not for beginners, but experienced surfers are in for a treat.
Wednesday the 5th of August still has decent 1-1.5m east swell but the wind turns southerly and chops it up a bit. Still okay.
After that, Thursday the 6th drops fast, and by Friday the 7th it’s back to small and poor.
Bottom line: hang tight through the flat spell, and Tuesday 4th August is the day to score. Clean, solid, and lined up – just expect company at the takeoff spot.
Rusty out.

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.
