The Lowdown
G’day, Rusty here. Look, I’ll be straight with you—the next week or so is a total write-off for a paddle. We’re looking at a long stretch of tiny, weak, poor-quality surf from now until late next week. From Saturday the 25th of July right through until Monday the 3rd of August, it’s all small dribblers under 2ft, short-period mush, and mostly onshore or cross-onshore breezes. Not worth getting wet.
The water temp at Yonabaru is sitting at 85°F, which is bang on average for this time of year—no surprises there.
Now, things *finally* start to show a pulse from Tuesday the 4th of August. That’s when a proper groundswell builds in. Tuesday morning sees some 4ft swell from the ESE with a very long 17-second period, but it’s still a bit messy with a cross-onshore breeze and the energy reading is strong. It’s marginal, but there’s hope. The standout window really opens up on Thursday the 6th of August. The morning session at Yonabaru (Okinawa) is the best on offer: a clean 5ft easterly swell, long 17-second period, glassy conditions with that slight air, and a very impressive combined swell energy—strong and juicy. That’s a solid groundswell with beautiful shape potential, though it might be a bit straight for a beach break—better for a reef or point, but if you’re in the water, it’ll be worth it. This swell stays solid through Friday the 7th and into Saturday the 8th, with waves building to 6–7ft (still early August). Those Saturday sessions get a bit chunkier at 7ft and the energy is very strong, but the wind turns cross and a bit stiffer, so it won’t be glassy. If you’re an experienced surfer, that Saturday morning (8th August) is another standout, just be aware the wind won’t be perfect.
By Sunday the 9th, the swell drops back under 3ft and the wind picks up, so the window closes.
Keep in mind this second-week swell is still a week and a half out—promising, but not locked in. If you can wait, target Thursday the 6th or Saturday the 8th of August for the best waves.

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.
