Alright, Rusty here again. Let's talk about what's on the menu for Yonabaru.
Honestly, the next week and a half is a real struggle. The surf is tiny, and the conditions are just ordinary for a long stretch. The water’s sitting at 81°F, which is about a degree and a half cooler than usual for this time of year – just a little chill in the water.
The big story is the waiting game. From now all the way through to the morning of Thursday, July 16th, there’s nothing worth getting wet for. That's nearly two weeks of small, weak waves or flat spells. There’s a tiny flicker on Monday the 6th in the afternoon with a 1ft swell from the ESE at a very long 15 seconds, but it's just surfable, nothing to write home about.
Then a big surge of energy hits from the SE on the 7th and 8th, with combined energy readings climbing into the thousands. But the wind is a complete mess—cross-onshore and gusty—so while the swell is there, it's blown out and choppy. By the 9th that SE swell is up to 15ft with a fresh breeze and lumpy conditions; that's expert-only madness and it's not even clean.
After that, the whole thing flatlines again for days. There’s a hint of hope on Wednesday the 15th afternoon with a 1ft ESE swell at 14 seconds, but we’re still waiting for something clean.
The one and only standout is Thursday morning, July 16th. We’ve got a 3ft swell from the ESE coming in at a nice long 13 seconds with glassy, clean conditions. The combined energy is a decent 284, and it’s the first time in this whole outlook the conditions are set to be good. That’s your session. But it’s a short window, because by the afternoon the cross-onshore wind kicks back in, and Friday the 17th brings a big 10ft ESE swell but with a fresh onshore wind that’ll spoil it.
So, plain and simple: it’s a drought until the morning of the 16th. If you’re a local, you know the drill. Crowds at Yonabaru are always a possibility, so on that Thursday morning, get down early.
Stay patient,
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.
