Alright folks, Rusty here. Let’s have a look at what’s on offer.
Alright, the short version is, we’ve got a long, quiet run ahead, but a real standout window is shaping up. The first few days are a write-off, so don’t bother paddling out until well into the week.
We’re looking at Yonabaru, the only spot on the radar. Over the first few days, Saturday the 4th through Monday the 6th, it’s flat with tiny, weak swell. The energy is barely there (41 down to 30), and the wind is a cross-off. It’s not worth wetting a suit. The water temp is about average for the time of year, nothing unusual.
Now, the real action starts to build on Tuesday the 7th. Tuesday morning kicks off with a glassy, dead-calm session. The swell is 3 ft from the SE with a long 13-second period. The energy is picking up (372). It’s surfable, but it’s the afternoon that’s the real gem. Tuesday afternoon we get a clean 4 ft of swell from the ESE, combined with a very long 17-second period. The energy climbs to 941. That’s a proper groundswell with great shape. The wind is glassy again. This is the best window of the whole outlook. Don’t sleep on it.
Wednesday the 8th sees a big spike in size, but it gets messy. The morning brings 8 ft from the SE with an 18-second period – that’s a lot of energy (4899), but it’s a cross-on breeze. By the afternoon, it’s 10 ft (5707) but the wind gets stronger and choppier. This is expert territory only, and it’s not clean. The wind is from the NE, which isn’t the optimum direction for the break. For the average surfer, this is a pass.
Thursday the 9th is a wipeout. The swell hits 13 ft to 15 ft from the SE, but the wind is a fresh cross-on breeze, making it lumpy and dangerous. The energy is massive (9560 to 12299), but it’s a mess. This is more for the kite crew than paddle surfers.
After that, from Friday the 10th through the rest of the outlook, the surf drops off a cliff. Friday has no swell at all. From Saturday the 11th into the third week of July, it’s tiny, mostly under 1 ft, and the wind stays onshore or cross-onshore. The energy is weak (under 30). It’s a long, flat spell. The second week is a dead loss.
So, the standout is undeniably Tuesday the 7th. The afternoon session is the pick of the bunch. Get on it, because the rest of the 16 days is a long stretch of poor or blown-out surf. The crowds might be around at Yonabaru, but on a Tuesday, you might get lucky.
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.
