Alright, let me break it down for ya. Look, for the next 16 days here in Okinawa, the surf story is pretty quiet for the most part. We've got a tiny window of clean, fun waves early on, but then it shuts down for a long stretch. Don't expect much to happen after that first couple of days.
Our main spot is Yonabaru. It's a pretty consistent little beginner-friendly break that's fairly exposed to the swell. The water temp is sitting about average for this time of year, so no surprises there.
The best bet of the whole period is Tuesday the 7th of July. We wake up to a glassy morning with the wind going completely calm. That's a major positive – it'll be smooth as a lake. Swell is a clean 3 ft from the ESE, and the combined energy is a decent moderate 484, so there's some push. Then Tuesday afternoon gets even better: the swell jumps to 4 ft from the SE with a nice long 16 second period, meaning proper groundswell lines with some energy (combined energy at 791). The wind is light offshore from the ENE. That afternoon session is the standout – clean, glassy, and punchy for a spot this size. It might get a bit crowded since it can get busy sometimes, but for that quality, it's worth it.
Before that, Monday the 6th is pretty ordinary. Small 1-2 ft waves with a side-offshore breeze. You can get wet but it's nothing special.
Then it all goes south. From Wednesday the 8th of July onwards, the wind cranks onshore and the swell gets too big and messy. Wednesday morning sees 8 ft from the SE with a 18 second period and a combined energy of 4475 – that's strong energy, but the wind is a cross-onshore at 15 mph, making it choppy and lumpy. That's expert territory at best, and the conditions are poor. Wednesday afternoon gets worse: 10 ft, 5928 energy, and 25 mph cross-onshore winds. Then from Thursday the 9th right through to the end of the second week, it's a write-off. Massive swell up to 15 ft, gale-force onshore winds, and storm after storm. For a beach-and-reef setup like Yonabaru, this is more interesting for kite surfing than paddle surfing.
There's a long gap with no worthwhile surf from Wednesday the 8th through at least Wednesday the 21st of July. Late in the run, around the 19th and 20th, we start to see some smaller 3 ft to 5 ft swell creep back in, but the wind is still onshore or cross-onshore, and the conditions are poor. Not worth the paddle.
So if you're keen, hit Tuesday the 7th of July for the cleanest, funnest waves of the outlook. After that, it's a long wait.

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.
