The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s comin’ our way.
Well, I gotta be straight with you – this outlook is a tough one. We’re looking at a long stretch of tiny, choppy, or blown-out conditions. There’s a real gap of surf that’s worth paddling out for, especially from now through the end of July. The first few days offer nothing but ankle-biters and poor scores, so we’re looking at a big wait.
The first bit of hope shows up on Sunday, July 26th, but we’ve got to be careful what we wish for. A pulse of swell hits midday, with a combined wave energy of 716 (moderate) and a swell from the SE at 6ft, but it’s getting hammered by onshore wind at 12 to 15 mph and there’s a risk of thunderstorms. The quality is poor, so that’s a no-go for a clean surf. The afternoon on the 26th actually gets bigger, with 7ft SE swell, but again, the wind is on it and messy. At that size, it’s bordering on too much for beginners, and the onshore wind will make it a real battle.
After that, July 27th and 28th drop back to tiny, weak waves with cross-shore winds. The only real stand-out, if you can call it that, is a brief window on the afternoon of July 28th. There’s a 7ft SE swell (734 energy), but it’s again wind-affected and messy. This is big, powerful, but messy – only for experts who don’t mind a bit of chop.
The rest of the outlook into early August is a sad story of small, short-period wind swell with onshore winds. We’re talking 0.7ft to 1ft with combined energy values barely cracking 100. The water is sitting at 83°F, which is a bit colder than normal for this time of year – just slightly off, but you’ll feel it.
For the first break, Yonabaru, it’s a beginner-friendly, fairly consistent spot, but it’s fairly exposed to the east. The best swell direction is NE, but we’re getting SE pulses on the bigger days, which isn’t ideal. The crowd profile says “sometimes,” so you might not be alone, but on these tiny days, it’ll be empty.
Honestly, there’s no standout classic session here. The whole 16-day window is a write-off for quality waves. If you’re desperate, the 28th afternoon has the most size, but with cross-shore wind and moderate energy, it’s more of a messy, expert-only affair. The rest of the time, it’s a lake. For the first week of August, it’s even worse – tiny, onshore, and weak. This is a classic summer lull.
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.
