The Lowdown

Alright, Rusty here. Let's have a look at what's on the table for Yonabaru.

Honestly, the next week and a half is a tough one. We're looking at a real dry spell for quality surf. The pattern is dominated by onshore winds and messy conditions, with the first decent window not showing up until Thursday the 17th. That's a solid 11-day stretch of poor surf to get through.

The only break in the area with any real recommendation is Yonabaru, a beginner-friendly spot that's fairly consistent. It's a fairly exposed break that prefers a NE swell direction.

The water temp is about average for this time of year, so no need to dig out the steamer just yet.

For the first week, from Sunday the 6th right through to Wednesday the 16th, it's a write-off. The wind is mostly cross, onshore, or cross-on from the NE through to the E, with speeds of 12 to 19 mph. Swell heights bob between 3 ft and 6 ft, but with short periods of 6-9 seconds and that nasty wind, the combined swell energy (221-717) is doing nothing for wave quality. It's all labeled "poor surf conditions," and I wouldn't bother paddling out.

Finally, we get a shift on Thursday the 17th. The wind swings to a light SSW at 9 mph, going cross-offshore. Swell drops to 2 ft from the E at 9 seconds, with combined energy of 143. The call is "surfable waves but very ordinary conditions," which isn't a ringing endorsement, but it's the first clean-ish moment we've seen. Then, Thursday afternoon gets interesting: the wind drops to a glassy 3 mph from the WSW. A 5 ft SE swell rolls in with a short 6-second period and 178 combined energy. Glassy conditions are a massive positive, but that short period swell won't hold much power or shape. This is probably the best of a bad lot, but it's only for beginners.

Friday the 18th morning holds some clean conditions with a light cross-offshore SSW wind and 5 ft swell from the E at 6 seconds (152 energy), but it's still just "surfable." After that, we're back into onshore junk through the weekend and into the start of the following week, with tiny 1.0 ft to 2 ft waves.

So, the standout window is the afternoon of Thursday the 17th. If you're a beginner and you absolutely need a paddle, that glassy moment with chest-high swell is your shot. For everyone else, this is a 16-day forecast with a whole lot of nothing. It’s the kind of run that’s not unusual for the area when the winds set in, but it doesn't mean it'll stay poor forever. Forecasts can always change.

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.
