The Lowdown
Alright, this is Rusty, and I’m looking at the next couple of weeks for Yonabaru. Honestly, the outlook is a real struggle. The water is sitting at 82°, which is a bit colder than usual for this time of year, but that’s the least of our worries.
We’ve got a long, dry spell ahead. From Sunday the 19th right through to the end of next week, there’s basically nothing worth paddling out for. The swell is tiny, mostly around 1.0ft to 1ft from the east, with a short, weak period of 9 seconds. The energy is minimal (16 on Sunday morning), and every single session is flagged as poor surf conditions. The wind is mostly light and cross-offshore, which would be nice if we had any waves, but we don’t. It’s just a flat, clean lake out there.
That blank run stretches all the way through to the morning of Sunday, July 26th. Even then, it’s still poor, with a messy 2ft from the southeast and a bump in energy to 148, but it’s onshore and useless.
The one glimmer of hope comes on Monday, July 27th in the morning. The forecast shows a sudden jump to 8ft from the southeast, with a period of 15 seconds. That’s a long-period groundswell, and the energy reading is a massive 2650. That’s serious power. But – and it’s a big but – the wind is blowing cross-onshore at 9 mph, making it choppy, and the report calls it marginal at best. For a beach break, that long period can make waves break too straight, and with that size, it’s only for experts. The conditions are rough, so honestly, it looks more interesting for a kite surfer than a paddle surfer. Everything after that session falls apart again, with strong winds and no real swell.
The last week of the forecast into early August is all strong offshore winds, but the swell is tiny, never getting above 4ft, and the energy is weak. The wind is so strong – hitting gale force on August 3rd – that even if there were waves, you’d never get into them.
So, the reality is there’s no standout spot here. The only break we have is Yonabaru, and it’s a tough wait. The best on offer is that Monday morning, July 27th, but it’s a messy, expert-only window. The rest of the 16 days is a write-off. Don’t hold your breath.
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.
