Table - best surf conditions forecast for Yonabaru over the next 16 days.
Alright, Rusty here, and let's be straight with you. The next couple weeks are lookin' tough for a proper session at Yonabaru. We've got some serious weather on the way that's gonna mess things up, with a lot of blown-out, dangerous conditions in the mix. Hold on to your board.
First up, Thursday the 9th and into Friday the 10th? Forget it. We're talkin' fresh to near-gale onshore winds, blowin' straight into this beach. The swell's actually huge – on Friday morning we're lookin' at a massive 31 ft swell from the SE with a very long 18-second period. That's so much energy the combined wave energy is at 55292, but it's way too big and wild for anyone. This ain't for paddlin'; this setup is more for the kite surfers if they're crazy enough. Even the morning of Saturday the 11th is a total mess with near-gale cross-onshore winds.
We get a bit of a lull from the 12th through the 19th, but the surf is tiny – just ankle to knee-high dribble. Winds stay mostly cross-onshore or onshore, so it's choppy and messy. There's a few moments of glassy conditions on Friday the 17th and Saturday the 18th mornings, but the swell is only around 1 ft to 2 ft from the east with a short period. Good for a float, but not a wave you can ride. The water temp is about average for this time of year.
The pattern shifts a little around the 21st of July. We see the combined swell energy jump up to 226 on Tuesday morning, then to a moderate 1331 Tuesday afternoon with a 6 ft swell from the east and a solid 14-second period. That's a better-looking groundswell, but conditions are still marked as poor surf. Tuesday afternoon has onshore winds with the swell, though the period suggests some power. It's not a clear call.
Then Wednesday the 22nd and Thursday the 23rd bring a new swell from the north and northwest, around 3 ft to 4 ft, but those onshore and cross-onshore winds keep it lumpy. By Friday the 24th, the swell is down to 2 ft. Honestly, there's no true standout window here for surf. The best you could hope for is maybe a sneaky glassy dawn patrol on Friday the 17th or Saturday the 18th for the tiniest of waves.
So what's the best on offer? If you are desperate, take the morning of Friday the 17th or Saturday the 18th for a glassy, tiny wave. It's not a surf report to write home about. Everything else is a battle.
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.
