The Lowdown

Alright, Rusty here. Let’s be straight with you: for the next week and a half, Yonabaru is a tough beat. The surf is tiny, the wind is messy, and the conditions are just plain ugly. We’re looking at a long, frustrating gap with barely a ripple worth paddling for. The water is sitting at a balmy 84°, which is pretty average for this time of year, so the only thing you’ll be doing is floating.

From Sunday the 13th right through to the morning of Friday the 18th, it’s basically flat with weak, choppy energy. The combined swell energy is mostly in the low-to-mid 100s—weak stuff. Winds are onshore or cross-onshore, and it’s just not happening. Don’t even bother.

Friday the 18th afternoon is still small and choppy, no good.

Then things get interesting. Saturday the 19th sees a spike of energy from the ESE, with a crazy-long 18-second period and combined energy hitting 455. But it’s messy. The wind is cross-shore and bumpy. That afternoon, we get 4.3 feet of ESE swell with a 16-second period and energy jumps to 1011. It’s still a bit lumpy, but the comment says "marginal." Not a standout, but a glimmer.

Sunday the 20th is where your best chance lies. Sunday morning we get 7.2 feet of E swell with a 15-second period and energy is a solid 2045. The wind is cross-shore, so it’s lumpy. But by Sunday afternoon, the wind swings cross-offshore at 22 mph, and the waves hold at a clean 6.6 feet from the east with a 14-second period and energy at 1559. This is your spot. That’s a proper groundswell, and with cross-offshore wind, it’ll be clean. The swell is over 5 feet, so this is more for intermediates and up. The long period (14–15 seconds) means look for a point or reef setup, not a beach break where it might close out. Crowds are “sometimes” a factor, so keep an eye out.

Monday the 21st drops off to 4.3 feet in the morning and 3.6 feet in the afternoon, still clean with cross-offshore wind, but the energy is fading. The rest of the week after that is small or messy, with another big pulse trying to show up around Saturday the 26th and Sunday the 27th. That’s 9.8 feet of ESE swell with 15-second period and energy over 5000, but the wind is cross-shore and the conditions are “marginal.” That’s for experts only, and it’s a long-range call—promising but less certain.

So, to put it simply: Sunday afternoon the 20th is the one to circle. Clean, solid, and worth the wait. For now, save your energy and wax.

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.
