Table - best surf conditions forecast for Yonabaru over the next 16 days.
Alright folks, Rusty here. Let’s cut through the noise and talk about what’s happening with the surf.
To be straight with you, the next 16 days are a real struggle. We’re looking at a long stretch of flat, blown-out, or just plain ugly conditions. The first week and a half is basically a write-off, and even when we do see some swell, the wind is going to ruin it.
We start off with absolutely nothing. From Friday the 10th through to Monday the 13th, the combined energy is zero (0). It’s flat, with a risk of thunderstorms and brutal easterly winds hitting 28 to 44 mph. That’s gale force, not surfable. Tuesday the 14th and Wednesday the 15th see a tiny pulse of 1 ft from the east, but the energy is weak (20 or less). Wednesday afternoon is the bright spot here – the wind goes glassy (3 mph) and the swell is 1 ft from the SE with a period of 11 seconds. At Yonabaru, that’s about as clean as it’s going to get, but it’s still a tiny wave. The water temp is 85°, which is normal for this time of year.
Then we get a gap of nothing really worth paddling for until the 18th of July. That Saturday morning, a lumpy 8 ft ESE swell hits with a short 8-second period, and the energy jumps to 744 – that’s moderate. But the wind is a strong cross-onshore (25 mph) and the report says it’s messy. This is a beach and reef setup, and with that much wind and short period, it’s honestly more interesting for kite surfing than paddle surfing. For a beginner spot like Yonabaru, 8 ft is too big anyway.
The 19th of July Sunday morning is a similar story: 8 ft from the SE with 931 energy, but again cross-onshore winds and choppy. Not good. The 20th and 21st keep the size up (6-8 ft) but with onshore winds and short periods (7-8 seconds). The swell direction is from the east, which is not the optimum NE direction for Yonabaru. It’s a long stretch of poor surf.
The final days from the 23rd to the 25th drop back to small, weak swell (2 ft to 3 ft) with energy under 153, and the wind is still cross-on or onshore. It’s just not happening.
The only standout is that Wednesday afternoon the 15th. If you’re desperate, you can get a tiny, clean, glassy 1 ft wave at Yonabaru. It’s not a day to drive for, but it’s the best on offer in a very poor run.
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.
