The Lowdown

Alright, crew, Rusty here. Let’s talk about what’s coming for the next couple of weeks.

Honestly, the 16-day window is a tough one. There’s a real gap at the start. We’ve got a stretch of nothing from now all the way through until the 11th of August – just gale-force cross-shore winds and stormy skies. It’s a rough start, but it happens.

The first real chance comes on Wednesday morning, the 12th of August. Yonabaru is the only spot that even flirts with being rideable. The wind finally turns offshore from the west at 12 mph, and the water temp is about average for this time of year. The swell is a tiny 2ft from the east, with a period of 11 seconds – that’s groundswell, but the energy is weak at 100 combined. It’s a beginner-friendly break, fairly consistent, and with that offshore wind it’ll be clean. But it’s "surfable but very ordinary". You might get a couple of little ones, but don’t expect much.

That Wednesday morning the 12th is your best bet. The afternoon sees the wind turn cross-off, and the swell gets even smaller. From there, the wind goes onshore for the rest of the window. The swell stays tiny – mostly 1ft to 2ft – with periods all over the place. The energy stays low, mostly under 200.

From the 15th of August onward, it’s all onshore wind from the east or southeast, with small, weak swell. There’s a little bump in energy on the 16th and 17th, with the 16th afternoon hitting 227 combined energy – but that’s a 2ft east swell with onshore winds. The 19th of August has a 4ft east swell, but it’s hammered by a strong onshore breeze at 28 mph, so it’s total junk. That kind of setup is more for the kite surfers than the paddle crew.

So, to be blunt: Wednesday the 12th morning is your only real window, and it’s small. The rest is a write-off. But don’t sweat it too much – these flat spells don’t last forever, and forecasts can change.

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.
