Alright folks, Rusty here. Let’s have a look at what’s on the table for the next couple of weeks.
Right off the bat, we’ve got a bit of a tease. Tuesday morning at Yonabaru kicks things off with some clean, glassy conditions. The water is sitting at a warm 83°, which is pretty much bang on average for this time of year, so no surprises there. The swell is a modest 3ft out of the ESE, with a very long period of 13 seconds. That’s proper groundswell energy, and the combined energy is a solid 484 (moderate). For a beginner-friendly spot, this is a nice, gentle introduction. The wind is glass, absolutely still, which means the surface will be like a mirror. It’s a good one for a longboard or a funboard.
Tuesday afternoon, the swell picks up a touch to 4ft, direction shifts a bit more SE, and the period stretches to 16 seconds. The wind turns light cross-offshore, keeping things clean. The combined energy jumps to 792 (still moderate). This is a really pleasant afternoon session.
Then Wednesday, the swell really starts to build. By Wednesday morning, we’re looking at 7ft from the SE, with a 17-second period, and the combined energy is a hefty 2296 (strong). But here’s the catch – the wind is cross-on at 9 mph, and it’s described as fairly choppy. The same goes for the afternoon: 8ft, even more energy at 3166, but still that cross-on wind. It’s not blown out, but it’s not super clean either. For a beginner break, 7ft to 8ft is starting to get a bit much, and the chop won’t help.
From Thursday (July 9th) all the way through to Monday (July 13th), the forecast gets ugly. We’re talking risk of thunderstorms, strong onshore winds, and a proper stormy setup. Thursday sees 11ft to 15ft of swell with a massive 7500 to 11251 combined energy, but it’s blown out with 19-22 mph onshore winds. That’s expert-only territory, and even then, it’s messy. By Friday and Saturday, the wind is howling at 31-37 mph, with no swell height recorded, just chaos. Sunday and Monday aren’t much better, with lumpy, choppy conditions and a drop in energy. The swell that does show up on Sunday afternoon is 5ft with a short 8-second period, which is just windswell junk.
There’s a real gap here. From the morning of July 9th right through to the afternoon of July 15th, the surf is either complete junk, too big with bad wind, or just plain flat. We’re talking over a week of poor to non-existent quality.
Finally, things start to look up around Wednesday, July 15th. The afternoon brings a 10ft SE swell, with a 10-second period. The combined energy is back up to 1993 (strong), and the wind is glassy again. That’s a big, clean swell. But it’s marginal for the spot due to tide. That’s the one standout in the second week: a big, clean swell, but a bit of a wildcard.
The rest of the period after that is a mixed bag. There’s a brief moment on Saturday, July 18th, with 4ft from the NW and clean cross-offshore winds, but the period is a short 7 seconds, so the energy is weak (166). It’s surfable, but ordinary.
So, the best of the window is Tuesday morning (July 7th) for the glassy, long-period 3ft groundswell at Yonabaru. The second best is the clean, building swell on Tuesday afternoon. The Wednesday sessions have size, but the wind makes them less appealing. The long-range standout on July 15th is promising but uncertain.
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.
