The Lowdown

Alright folks, Rusty here. Let’s be straight with you – the next two weeks are a bit of a mixed bag for Yonabaru. We’ve got some solid energy on the way, but it’s going to take patience to line up with the right wind. There’s a good chunk of the forecast with no real reason to paddle out, so pick your moments carefully.

The first real action we can look at comes on Thursday, September 3rd. There’s a moderate swell running with 7ft of east swell, a period of 11 seconds, and a combined energy of (1093). That’s got some decent power behind it, but the wind is a cross-offshore from the NW at 12 mph, which should keep things fairly clean. The water temp is sitting at 84°F, which is about average for this time of year, so no surprises there. For beginners, this swell is a bit too big, so it’s more for the competent crew.

After that, we hit a real dry spell. From Friday the 4th right through to Monday the 14th, the conditions are just poor. Small choppy waves, funky wind directions, and onshore slop. There’s a few days of small, weak swell around 2ft to 4ft, but the wind is either cross-on or onshore, making it a real struggle. Honestly, it’s not worth your time.

We finally see a glimmer of hope on Tuesday, September 15th, during the afternoon. We’ve got a 6ft east swell, 7-second period, and combined energy (309). The wind swings around to a light SSW cross-offshore at 9 mph, and the forecast says clean conditions. This is the best window in the whole run. It’s not huge, but it’s rideable and clean.

Wednesday, September 16th, brings a big pulse. The afternoon sees a 12ft east swell, 10-second period, and a massive combined energy of (2124). That’s a lot of juice. But the problem is that for Yonabaru, this is just too big. The forecast explicitly says the swell is predicted to be too big for this break. The wind is light and cross-on, so it’s not even clean. This one is for experts only, and even then, it’s a miss. After that, the surf drops off fast into the end of the period with tiny 1ft leftovers.

So, the standout here is Tuesday afternoon, September 15th. It’s not a classic, but it’s the cleanest, most manageable surf on offer. If you’re in the water, that’s your window.

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.
