Rusty here again. Let's run it down.

We're in a bit of a dead zone for the first few days. From Friday the 3rd all the way through Monday the 6th, Yonabaru is flat out tiny. We're talking about ankle-snappers at best, 0.5 ft or so from the ESE with no energy behind it. The wind is cross-off, so it looks clean, but there's nothing to catch. Save your wax.

Things wake up in a big way on Tuesday the 7th. The morning session is looking sweet: glassy, with the wind coming light out of the south at 3 mph. Swell jumps to about 3 ft from the SE with a solid 13-second period. That energy reading climbs to 431 (moderate), so you'll feel some punch. This is a real window of opportunity. The afternoon is even better. The swell builds to 5 ft, the period stretches out to a very long 18 seconds, and the energy jumps to a strong 1149. Wind stays light from the SW, keeping it clean. That Tuesday afternoon is the cream of the crop for this whole 16-day stretch. Water temp is 81°, which is a touch colder than average, but nothing a boardies-and-rashguard crew can't handle.

Wednesday the 8th is a whole different ball game. The swell jumps to 8 ft in the morning and nearly 10 ft in the afternoon, still from the SE with that 18-second period. The energy readings are massive – up to 5308. But here's the catch: the wind swings onshore from the ENE at 9 mph, and it's going to chop it up. That size and that wind is only for the experts, and even then, it's going to be a battle with the conditions. Tide might factor in too.

Then the wheels fall off. From Thursday the 9th, a strong onshore flow hits, with winds from the ENE at 16 mph, building to 22 mph on Friday the 10th with a risk of thunderstorms. The surf gets completely blown out or non-existent, with energy readings dropping to zero.

We hit a long stretch of nothing from Friday the 9th through Tuesday the 14th. A couple of tiny 1 ft ripples show up on Sunday the 12th and Monday the 13th, but with a moderate cross-shore wind, it's a total mess. Wednesday the 15th and Thursday the 16th see things clean up, but the swell stays at 1 ft to 1 ft with almost no energy. The last few days, all the way to Saturday the 18th, are just small and choppy with a moderate onshore breeze. If you don't make it out on Tuesday the 7th, you're likely left waiting for the next system. Get it while you can.

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.
