The Lowdown
Alright crew, Rusty here. Let’s break down what’s coming.
We’ve got a long, quiet stretch to start. The first real chance to surf comes on the morning of Tuesday, 4 August, but before that we’re looking at about 10 days of nothing worthwhile. The waves are tiny, the wind is mostly cross-onshore, and it’s just not worth paddling out. There’s a few glassy moments, but with wave heights of only 1 foot to 1 feet, it’s a total washout. It’s a patient wait, but that’s how it goes sometimes.
The real standout is the morning of Wednesday, 5 August at Yonabaru. That’s your best window. We’ll have a clean 4ft groundswell from the east, with a very long period of 15 seconds. That’s real energy and good shape. The wind will be glassy out of the ESE, so the waves will be smooth and clean. The combined energy of all swells directed here will be moderate at 679. It’s a beginner-friendly break, so the size is fine for most, and the glassy conditions will make it a treat. Just remember, that long period swell can make a beach break a bit straight, but it’s still the best of the run.
Another good option is the morning of Friday, 7 August, also at Yonabaru. You’ll get a 4ft east swell with a 15-second period and a clean cross-offshore wind from the NNW. The combined energy will be moderate at 545, and the waves should be clean and have some shape. A solid backup.
The crowd at Yonabaru is "sometimes" busy, so expect a few others out, but nothing crazy.
Water temperature is about 84°F, which is normal for this time of year, so no wetsuit needed.
Bottom line: the first week and a half is a dud. The best sessions are the morning of Wednesday, 5 August, and the morning of Friday, 7 August. Get on it.

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.
