The Lowdown

Alright folks, Rusty here. Let’s be straight with you – the next couple of weeks are looking pretty grim for a paddle. We’ve got a long stretch of nothing good to ride, so don’t be in a rush to wax up.

The only spot on the radar is Yonabaru. It’s a beginner-friendly, fairly consistent break that’s fairly exposed, but it’s going to be a long wait. The first week, from August 7th right through to the 14th, is a total write-off. The wind is howling, with gale-force gusts on Friday the 7th hitting 50 mph, and we’ve got stormy conditions and poor surf. The combined swell energy is off the charts in a bad way – over 8000 on Friday morning – but it’s totally unsurfable. You’ll see a few small bumps of 2 ft to 3 ft from the east, but the wind is either cross, onshore, or just too strong. Leave the board at home.

There’s a glimmer of hope right at the end of the run. On Saturday, August 15th, we finally get a break in the rubbish. The wind swings offshore from the west, and we get a clean, glassy morning session. The waves are small, only 2 ft, but the easterly swell has a long 11-second period, so there’s a bit of push. The combined energy is moderate (122) and the conditions are clean. It’s not a standout in size, but after all that wind and chaos, it’s the best we’ve got. The water temp is about average for the time of year, so no need for a thick wetsuit.

After that, it’s back to small, weak, and onshore slop through the rest of the week. Sunday the 16th has a brief moment of offshore wind, but the swell is a mixed-up 3 ft from the northwest with a short 7-second period – not worth the effort. By Monday the 17th, the wind switches back onshore and it’s choppy again. The last week, from the 18th to the 22nd, is a flat, onshore mess with barely any energy. Swell heights drop to 1 ft, periods are short, and the combined energy is weak (24 to 103). It’s a classic dead spell for the area.

So, if you’re desperate, Saturday the 15th is the only call. It’s small and clean, and you’ll have the place to yourself. But honestly, this is a kite surfer’s forecast for the first week, not a surfer’s. Keep your eyes on the charts, things can change, but for now, it’s a long wait.

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.
