The Lowdown
Alright, Rusty here. Let's look at what's going on at Yonabaru over the next couple of weeks.
Honestly, it's a slow start and it stays that way for a long time. From now through July 26th, there's just not much to get stoked about. We're looking at tiny swell, mostly around 1 to 2 feet, coming from the east or southeast. The water is sitting at 80.8°, which is actually a bit cooler than usual for this time of year. The wave energy is weak for that whole stretch, and conditions are consistently being called "poor." Even when we get a glassy morning on the 21st with light winds from the west, the swell is just too small to ride. That's a solid 12-day gap with nothing worth paddling out for.
Finally, things start to change around July 27th. Monday the 27th sees a jump in size, with a 3.6-foot southeast groundswell arriving, period at 12 seconds, and moderate energy kicking up. But the wind is a problem – it's onshore or cross-onshore from the east-southeast at 16 mph, making it choppy and messy. That's still marked as poor surf.
Now, here's the standout, and it's a proper big one. Tuesday the 28th of July is where the ocean wakes up, but it's not for everyone. Swell pumps up to 16 feet in the morning, climbing to a massive 20 feet by the afternoon, both from the east-southeast. The period is very long – 15 seconds – and the combined energy is monstrous. That is serious, heavy water. This is for experts only, no doubt about it. The cross-onshore wind at 16 mph is going to put a lot of chop on top of that power, so it won't be clean. Honestly, with that much strength and the wind on it, this setup looks more interesting for kite surfing than paddle surfing. After that, the swell drops off quickly and the outlook for the rest of the week goes flat and weak again.
So, the one true standout is that Tuesday the 28th of July, but it's a big, gnarly, windy session for the brave. Most of the 16-day window is a write-off for decent 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.
