The Lowdown

Alright folks, Rusty here. Let's have a look at what the next couple of weeks are shaping up like for Yonabaru.

To be straight with you, the start of the period is a bit of a write-off. We’ve got some swell on Wednesday the 2nd but the wind is howling onshore from the east, making a mess of things. The wave energy is moderate (574), but with that chop, it’s not worth paddling out. You'd be better off waiting. Thursday the 3rd offers a glimmer of hope with some cleaner conditions as the wind swings offshore from the NNW, and the swell energy builds to a solid moderate (838). The waves are around 6 ft from the ESE with a 10-second period, but the forecast is calling it marginal. It's a possible early-morning strike mission for a beginner, but don't expect perfection.

Friday the 4th and Saturday the 5th see the swell drop right off, with smaller waves and poor conditions. The energy levels dip into the low 200s and 300s. Not much to get excited about. Sunday the 6th is still small and marginal, with the wind holding offshore from the NNW. The water temp is about average for this time of year, so no need to worry about a wetsuit just yet.

The real looker in this forecast is shaping up for the middle of next week. On Wednesday morning the 9th, we see the swell start to build back up, hitting 5 ft from the NNW with a 9-second period and a moderate energy reading (538). Conditions are clean with a cross-offshore breeze. It’s still just a marginal call, but the potential is there. Thursday the 10th sees a pulse of 8 ft from the NNW, but the wind goes cross-shore and the period drops to 7 seconds, making it choppy and poor. That’s a miss.

Now, the first true standout comes in the second week of the forecast. On Tuesday the 15th, the afternoon session sees a solid pulse of 8 ft from the east, but it's the period that gets your attention – a long 14 seconds. That’s real groundswell energy, and the combined energy is a very strong 2411. The wind is cross-shore, so expect some texture, but this is a powerful set of waves. This size is for the experienced crew only; it’s over 8 ft and will have some serious punch. The long period means it will be a bit walled up at the beach, so keep your wits about you.

Wednesday the 16th follows up with a similar, slightly smaller offering: 7 ft from the east, still with a long 12-second period and strong energy (1375). The wind is a gentle cross-shore, which is about as good as we can hope for. This is likely the best bet of the whole window. The period is long, so those point breaks and reefs will be the spots to be. Yonabaru is a fairly exposed spot, and the optimum swell direction is from the NE – the east swell is close enough to get it working.

Overall, the first week is a struggle. The real action is squarely on the 15th and 16th of September. Those two days have the size, the energy, and the cleanest conditions we're going to see. It's a long-range call, so keep an eye on the charts, but that’s where the gold is.

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.
