The Lowdown

Alright, folks, Rusty here. Let’s talk surf for Yonabaru. This one’s a funky start – we get a massive wall of water right away, but it’s just too much for the spot. Then we grind through a bunch of slop before a late window of clean waves shows up way down the line.

First thing Tuesday, August 25th, we’ve got a huge 13ft to 15ft groundswell from the ESE and E, with a very long 16 to 17 second period. The combined energy is off the charts at 10043 and 9959 – that’s serious power. But for Yonabaru, that’s just too big. The wind is crossing or cross-offshore, so it’d be clean, but this is a beginner spot and that size is only for the hardcore crew. It’s a miss for us.

Wednesday and Thursday, August 26th and 27th, we drop right off. The swell crashes down to 1ft with a weak energy reading of 85, and the wind is all over the place – cross-off and cross with a fresh breeze. It’s just flat or poor, nothing to wet the wetsuit for.

Then we hit a real dry spell. From Friday, August 28th, all the way through to Tuesday, September 8th, the conditions are poor. The wind is mostly onshore or cross-onshore, the swell is short-period or messy, and the energy is low to moderate (between 55 and 1252). There’s a couple of days in there with some size, like 7ft to 10ft on the 29th and 31st, but the wind is ruining it – cross-on, lumpy, and sloppy. It’s a kite-surfing setup, not a paddle-surfing one. The water temp is about average for the time of year, so no surprises.

Now, here’s the light at the end of the tunnel. On Thursday, September 3rd, we finally get a winner. That morning, we’ve got a solid 8ft groundswell from the NW with a 12-second period. The wind is offshore from the WSW at 15 mph, and the energy is a strong 1493. That’s the standout. The afternoon holds up too, with a 6ft NW swell, gentle offshore wind at 9 mph, and energy at 1053. This is the best on offer: clean, offshore, and a decent size for experienced surfers. It’s eight days out, so keep a loose eye on it, but it looks promising.

After that, from Friday, September 4th, through to the morning of September 9th, it’s back to poor conditions. The swell is small, the wind is cross or onshore, and the energy is low. It’s a quiet end to the forecast.

Rusty out.

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.
