The Lowdown

Alright, let’s look at the ocean. It’s got a mean streak this week. The water’s at 87°, which is a touch warmer than normal for this time of year, so it’s gonna feel like a warm bath.

Wednesday morning at Yonabaru (Okinawa) sees the first push, with a 7ft east swell at 17 seconds. The energy is strong at 2671, but the wind is cross-onshore, kicking up chop. It’s not worth your time. The afternoon turns worse with a storm risk and the swell bumps to 8ft, but the wind picks up and it gets messy. Thursday is a complete washout. The swell jumps to 13ft and then 15ft, but with 22-25 mph cross-shore winds, it’s going to be a complete mess. That’s a lot of water moving, and it’s not for the faint of heart. This is kite-surfing country, not paddle surfing.

Now, here’s where it gets interesting. Friday morning, August 7th, the wind swings to a cross-offshore and it’s glassy. The swell is a solid 18ft from the east with a 17-second period, and the energy is enormous at 31087. The catch? It's way too big for this break. This is strictly for the experts, and even then, it’s a wild card. The afternoon is even more extreme, 25ft from the NNW, blowing near-hurricane force at 78 mph. That is a full-on survival session. The ocean is furious, and Yonabaru isn't the place to be.

After that, the bottom falls out. Saturday through Tuesday, the swell drops to under 3ft, and the wind is all over the place. It stays clean with cross-offshore breezes, but there's just no power in the water. The energy readings are weak, in the 100-500 range. It’s flat and frustrating.

The next little blip is Wednesday, August 12th. A small 3ft NW swell shows up with a 10-second period, and the wind is light and cross-offshore. It’s clean, but very ordinary. The energy is a weak 139. You might get a few crumbly ones if you’re desperate, but it’s not going to be memorable.

For the rest of the second week, it’s a flat spell. The swell stays around 2ft to 2ft, with light winds, but there’s just no push. The energy readings are in the 50-150 range, which tells you all you need to know. It’s a dead period. The long-range forecast doesn’t offer any hope, just tiny, weak swells that won’t break properly. It’s a blank run, and for this area, that’s just how it goes sometimes. The only real standout on the whole board is that Friday morning, but it’s a beast that’s only for the brave. Everything else is a wash.

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.
