The Lowdown

Alright folks, let’s be honest, the next couple of weeks are a bit of a bummer. We’re looking at a long stretch of small, messy surf. If you’re keen to get wet, there’s one day that stands out, but otherwise, it’s a waiting game.

The start of the week, Saturday the 8th and Sunday the 9th, is a total washout. Strong southerly winds are blowing right across the break, chopping up the ankle-high waves. Swell is around 2ft with a weak, short period, and the energy is weak (106-125). The water is a warm 86°, a touch warmer than average, so you’ll just need a rashie. But don’t bother.

Monday the 10th and Tuesday the 11th see a bit more energy, but it’s all cross-onshore and lumpy. Swell picks up to about 3ft with a longer 14-second period, and the energy is moderate (363). But the wind has it all chopped up. Not worth it.

Wednesday the 12th is the first real chance. The wind goes light and glassy in the afternoon, and even though the swell drops to around 2ft, the clean face makes it rideable. It’s surfable but very ordinary. Same can be said for Sunday the 16th – glassy in the morning with a 2ft swell, clean but small.

The standout is Monday the 17th. This is the day. The swell pushes up to 3ft out of the east with a 12-second period, and the energy is moderate to strong (325). Light offshore winds in the morning swing cross-offshore in the afternoon, keeping it clean. This is the pick. Yonabaru is fairly consistent, so you’ll get waves.

Tuesday the 18th sees the swell jump to 5ft, and the energy gets strong (649-702). But the wind turns onshore, making it a lumpy, closed-out mess. At this size, it’s too big for beginners, and with the wind, it’s only for experts, and even then, it won’t be fun.

After that, it fades away. The rest of the week and into the next is tiny, with weak winds and no swell. There’s a blip on Saturday the 23rd with a very long-period groundswell (16 seconds) but it’s only 1ft. Forget it.

So there you have it. The 17th is your day. It’s not a classic, but it’s the best we’ve got. The rest is a waiting game. Forecasts can change, and it rarely stays this poor for long, so keep an eye on it. But for now, keep the board in the car and the wax in the shade.

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.
