The Lowdown

Alright, folks, Rusty here. Let's have a look at what the ocean's got cookin' for Yonabaru over the next couple of weeks. It's a bit of a mixed bag, but there's a window of pure chaos and a possible gem hidden in there.

The Long View

Right off the bat, the surf is pretty ordinary. We're looking at small, weak waves for a few days. The energy is low, around 66 to 186, which is nothing to write home about. It’s the kind of stuff that only gets you out if you're desperate for a splash. The water is sitting at a warm 87° and is running a touch warmer than average for this time of year, about 3° up.

The real story is the arrival of a serious pulse of energy mid-week. It starts to build on Tuesday, but it's still messy with light cross-onshore winds. By Wednesday morning, we're seeing some size, around 8ft, but the wind is making it choppyydoo and not all that inviting. The energy numbers are climbing though – you can feel the ocean getting restless.

Then, Thursday rolls around and things go absolutely nuts. The swell jumps to 15ft and keeps on climbing. The energy readings are enormous, hitting 16066 and then 19040. This is a full-blown, hold onto your hat, big-wave event. The problem is, it's way too big for Yonabaru. The wind is actually offshore and clean, which is a tease, but the sheer size and power of this swell will make it a washing machine. This is not a beginner wave, and honestly, even for experts, this spot is going to be maxed out and dangerous. By Friday, the wind goes nuclear – we're talking severe gale and violent storm force — with a big, stormy swell coming from the NNW. It's a full-blown no-go zone, not just for paddling, but for anything less than a jet ski.

Saturday – The Standout

Now, here's where it gets interesting. After the fury, the ocean starts to settle. Saturday morning, August 8th, the wind swings around to a gentle offshore breeze, and the swell drops to a more manageable 7ft from the NE. The energy has backed off to 1462, but it's still got some punch. This is looking like the best conditions on offer. The wind will groom those faces to perfection, and while it's still a solid size, it's within the realm for experienced surfers. Saturday morning is your window. It's not the biggest, but it's the cleanest it's going to be all week. The crowd factor here is a gamble, so you might have to share.

The Letdown

After that, it all fades away. The wind goes onshore and stormy again, and the swell just dies. From the 9th through to the 17th, we're looking at tiny, weak waves. The energy drops back down to the low hundreds and even double digits. It's a whole lot of nothing. The wind is mostly cross or cross-shore, making any little bump messy. There are a few glimmers here and there, like the clean but tiny surf on the 13th and 15th afternoons, but they're not going to get your heart racing. We're talking ankle-biters in the 1ft to 3ft range.

So, keep your eyes on Saturday the 8th. Get your fix then, because it's going to be a long, flat stretch after that. I'll be out there, trying to find a corner.

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.
