The Lowdown

Right, folks. Rusty here. Gotta be straight with you – this is a tough one. The next couple of weeks are looking pretty grim for a paddle.

The only spot on the radar is Yonabaru, a beginner-friendly break that's fairly consistent. The water temp is sitting at 85°, which is pretty much average for this time of year – no surprises there. The trouble is, for almost the entire 16-day window, we’re getting poor surf conditions. There’s a long stretch of nothing worthwhile from now until Wednesday the 20th of August, with only one tiny glimmer of hope.

Let’s walk through it. Starting on Tuesday the 11th of August, we've got tiny, weak swell (combined energy of all swells directed here at 219) out of the east at 3ft, but a mean cross-on shore wind from the south-east is making it choppy and poor. That’s the story for days. Wave heights drop even lower, and the wind keeps misbehaving.

The one moment that almost counts is Wednesday afternoon, the 12th of August. We get a bit of offshore wind from the west, and the conditions clean right up. The swell is still tiny at 2ft from the east, and the energy is weak (94), but it’s surfable. If you’re desperate for a splash, that’s your window, but don’t expect any power.

After that, it’s back to onshore winds and flatness for over a week. There is a pulse of energy forecast for Thursday morning the 20th of August – the combined energy of all swells directed here jumps to 762, with a 8ft swell from the south-east. But the period is a short 8 seconds, and it’s being hammered by a fresh cross-on shore wind at 22 mph. The setup looks more interesting for kite surfing than paddle surfing. Definitely not one for beginners.

The rest of the month is more of the same: onshore winds, messy seas, and very little to get excited about. A few readings show no swell at all.

So, to be honest, there’s no standout session here. The forecast can change, but right now, this is a blank run. Hang tight.

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.
