Alright, this is Rusty. Let's look at what we've got for the next couple of weeks.

First off, I'm not gonna sugarcoat it: the start of this forecast window is a brutal one. We're looking at a solid week of nothing good on the cards. There's a massive swell hitting on Friday the 10th, with a huge combined energy of 42,334 and a pumping 28 ft SE swell, but that's blowing in with a 31 mph onshore wind. It's a total mess, and way too big for anyone. That gets followed by gale-force winds and storm after storm right through the weekend. It's frustrating, but for a spot like Yonabaru, that's just how it goes sometimes.

The first glimmer of hope doesn't come until Monday the 13th, but with tiny waves, choppy conditions, and cross-shore winds, it's really not worth paddling out for. The whole first week is pretty much a write-off. The surf stays tiny, waist-high at best, with a mix of cross and onshore winds. There's a couple of glassy moments on the 15th, but the swell is just too small to do anything with.

Now, we have to wait until the second week. The pattern shifts. On Thursday the 23rd, we finally see a change. The wind swings to a light cross-offshore from the NNW, and the swell builds to a solid 6 ft from the east. The combined energy jumps to 442, which is a decent amount of grunt. The conditions are clean, but the forecast is only calling it marginal. Still, it's the first sign of life.

The real standout, the one you want to circle on the calendar, is Saturday the 25th. That morning, Yonabaru is looking clean with a light offshore breeze from the WSW. The swell is a fun 4 ft from the east, with a period of 10 seconds, giving it some nice shape and energy (271). The wind is light, the sky is clear, and the forecast is calling for good surf conditions. That's the pick of the patch. It's not a giant day, but after two weeks of nothing, it's a gem. Just be aware that Yonabaru can get a crowd sometimes, so get in early.

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.
