The Lowdown

Alright, Rusty here, let's have a look at what's on the menu for this stretch of coast.

Honestly, this doesn't look like a great run for a solid paddle. The whole 16-day window is a bit of a struggle. We've got a couple of mornings that might be worth a glance, but you'll be working for it. There's a long gap of poor conditions after the first couple of days, so don't hold your breath for a long session.

Your best bet, and really the only standout, is Yonabaru on Thursday the 3rd. It's not perfect, but it's the best of a mixed bag. Thursday morning you're looking at a solid 7.5ft from the east with a 10-second period, packing a punch with a combined swell energy of 1156. That’s strong. The wind is a bit awkward from the north at 15 mph, running cross-shore, so it won't be glassy. It'll be a bit workable for the experienced surfer, but that size is getting into the "experts only" territory. The water is sitting at 83.7°F, which is bang on average for the time of year. Thursday afternoon the swell drops a touch to 6.9ft, still from the east, and the wind swings north-west at 12 mph, going cross-offshore, which cleans it up nicely. This is probably the window to aim for. Remember, Yonabaru is a beginner-friendly break generally, but with that much swell, it's not a day for learners.

After that, Friday the 4th sees the swell drop right off to under 3ft and the wind swings onshore from the southwest at 15 mph. From there, it’s a long, bleak run. For the next week and a half, everything is rated poor. There’s a tiny glimmer on Saturday the 5th afternoon where the wind goes glassy from the east-southeast at 3 mph and the swell is only 2.3ft, but the wave comment calls it "very ordinary." The combined energy is a weak 78. It’s basically a flat, choppy mess from there on.

We don’t see any real improvement until Friday the 18th, which is over two weeks out. That morning there’s a chance of a tiny 2.3ft east swell with a 12 mph west-southwest offshore wind. It’s "surfable but very ordinary" with a combined energy of only 137. That’s not a standout, just a hint of something better. So, for the next few weeks, don’t get your hopes up. The forecast is unlikely to change much for a while.

Bottom line: Thursday the 3rd afternoon is your only real shot. Get in the water then. Otherwise, you might want to find something else to do.

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.
