Alright, Rusty here, let’s talk about what’s goin’ on.
Right off the bat, it’s a grim start. The first swell we see rolls in Wednesday morning, but it’s coming from the wrong direction for our main spot, Yonabaru, which really wants it from the NE to work. We got SE swell and a cross-on wind, making things choppy and messy. The water’s at a warm 84°, pretty average for this time of year, nothing unusual.
Thursday and Friday get progressively bigger and uglier. By Friday morning, we’re talking a massive 31 ft swell with a very long 18-second period from the SE, and winds howling at 31 mph onshore. The combined energy shoots up to (58383) — that’s extreme. This isn’t a paddle-surf day; it’s more of a “stay on the beach and watch” or a kite-surfing scenario. It’s far too big for anyone but the experts, and even then, the wind is trash.
After that, the weekend and most of the following week is a write-off. We get days of thunderstorms, onshore and cross-on winds, and tiny, weak swell or none at all. There’s a gap from Saturday the 11th right through to the following Wednesday the 15th with nothing worth mentioning.
We do see a little flicker of hope on Thursday the 16th of July. Morning winds turn light and onshore from the ENE at just 3 mph, almost glassy. It’s still small at 6 ft swell from the ESE, with a moderate 9-second period, giving a combined energy of (575). The wind is the best we’ve seen in a long time, and that small, clean swell could offer a few fun ones for the beginner to intermediate crew. It’s not a standout by any stretch, but compared to the rest, it’s the best on offer.
Looking further out, the surf picks up again around the 20th of July. Monday the 20th shows a solid 6 ft to 7 ft swell from the E, with a long 16 to 18-second period. The wind is still cross-on from the SSE, keeping it a bit lumpy. This is promising, but it’s a week and a half away, so we keep the excitement in check. The energy is moderate, around (2038).
The real potential may come on Tuesday the 21st of July. Clear skies, wind straight onshore but light at 9 mph from the E. The swell holds at 8 ft from the E with a 16-second period, which is long and powerful (2709 energy). That’s expert territory size-wise, and with that long period, Yonabaru might not shape up perfectly — long period E swell can break a bit too straight on a beach setup. But if you’re an experienced surfer and the wind stays manageable, it could be the wild card.
After that, the pattern looks mixed again with storm threats and shifting winds through the 22nd and 23rd. The swell direction swings around to the NW and N, which isn’t what Yonabaru likes.
So, truth is, there’s no real classic standout in this window. If I had to pick, I’d say keep an eye on Tuesday the 21st of July for the biggest, most powerful swell, but only if you know what you’re doing. For a cleaner, more manageable wave, the morning of Thursday the 16th is your best bet, even though it’s small.
Keep your head up, forecasts can shift, especially that second week.
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.
