The Lowdown
Alright, let's switch gears and talk in feet and miles per hour, keeping it real for the local crew.
Looking at the full 16-day picture for the Yonabaru area, I've got to be honest: the wait is the biggest story here. We're looking at a long dry spell of tiny waves that just won't give you any push. The first ten days are a real flat spell, with waves hanging around 1 foot (combined energy of all swells directed here often below 30). It's gonna be a long, frustrating stretch.
Tuesday, July 14, kicks it off with nothing going on—just 1-foot waves from the east and funky winds. That same, sad story sticks with us all the way up to Saturday, July 26. We get some real glassy, clean conditions on Wednesday and Thursday, July 22 and 23, but with no swell to speak of, it's just a calm pond. A real tease.
As we get into the last few days of July, there's a flicker of hope. Sunday, July 26, sees a jump in period with a 15-second groundswell from the east-southeast, but the height is still only about 1 feet, and the wind is onshore/cross-onshore, messing up any chance of a clean wave. The energy is starting to climb into the 86 range. Then Monday, July 27, things get a little more serious. The swell ticks up to about 3 feet from the ESE, with that same long 15-second period. The energy jumps up to 406. The catch is the wind is still onshore, leaving the surface choppy.
The only spot that might offer something worthwhile is Tuesday, July 28. We're looking at a head-high 3-foot wave from the east, with a very long 16-second period. The energy is pumping at 897, so there's some real power in the water. *Yonabaru* is fairly exposed and likes swell from the NE, so the east direction is close enough. The bad news is a moderate cross-shore wind will bring some chop, so it won't be perfect. That morning window is the one to watch for the more experienced surfers. The water is a bit colder than usual at 28°, so you might want a light suit.
By Wednesday, July 29, a full-blown storm rolls in. The swell is up to 5 feet, with massive energy over 1225. But with storm force winds hitting 60 mph, it's going to be an absolute washing machine. Stay out of the water that day.
So, the bottom line: a long, flat spell followed by one day of solid but messy surf. Tuesday, July 28 morning is the only real chance for a session, and it's for the experienced guys who don't mind a bit of chop.

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.
