Table - best surf conditions forecast for Yonabaru over the next 16 days.
Right, folks, Rusty here. Let's have a look at what's on the cards for the next stretch.
To be straight with you, the first week plus is a real write-off. We've got a solid ten days of poor conditions, with no surf worth mentioning until the 19th of July. The wind is mostly cross-onshore or onshore, often strong, and the water’s a mess. You can forget about a paddle for a while.
Now, the standout – and it’s the only real window of opportunity – is the morning of Sunday the 19th of July at Yonabaru. The winds go glassy, which is a massive plus, making for what should be clean, smooth conditions. The swell comes in at 4 ft from the east, with a very long period of 14 seconds. That’s proper groundswell. The combined swell energy is a solid 494 (moderate wave energy), and with that direction, it’s a good match for the optimum. The water temp is about 84° which is around normal for the time of year. This is the one to aim for, but keep in mind it’s a beginner spot with a fairly consistent wave, and crowds are sometimes a thing. The afternoon of that same day gets a cross-on breeze, so it’ll get a bit bumpy.
After that, the 20th and 21st of July seeing the swell building to 5 ft and 5 ft, but the wind swings onshore, so those are blown out. The 22nd to the 25th of July stays small, messy, and the swell drops off, with the 25th morning seeing a tiny 0.3 ft long-period swell which isn't going to do anything.
So, for the full 16 days, there’s really only that one morning on the 19th of July that’s worth getting excited about. The rest is a long wait for clean conditions.
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.
