G’day, I’m Rusty, and I’ve got the surf lowdown for your area over the next couple of weeks. The pick of the whole forecast is going to be Tuesday the 7th of July, with a real standout session on the cards for Yonabaru. Before that, though, we’ve got a bit of a waiting game. The early part of the outlook is pretty flat and ordinary, with nothing worth paddling out for at Yonabaru on Sunday the 5th or Monday the 6th – those tiny waves under 2 feet and cross-off winds just aren’t giving us much to work with.

Come Tuesday morning the 7th, things suddenly get interesting. The swell comes up to 3 ft from the ESE, and check it out – we’ve got glassy conditions with NW winds at 6 mph. That is a major positive, meaning the surface will be real clean. The combined wave energy is moderate at 484, and by Tuesday afternoon it jumps to 4 ft from the SE with a very long period of 16 seconds, and the wave energy ramps up to 739. The wind stays glassy from the NW at 6 mph, and the forecast is calling for very good surf conditions. That afternoon session is the top standout of the whole 16-day run – clean, long-period groundswell pushing in with moderate energy. The water temp is sitting at 82°, which is about average for this time of year, nothing unusual there.

Now, Wednesday the 8th sees the swell jump up big time – 8 ft in the morning, 10 ft in the afternoon from the SE, with a long period of 18 seconds. That’s big surf, over 8 ft, so it’s really only for experts. But the problem is the wind goes cross and then cross-off from the NNE at 12 to 12 mph, plus the combined energy is strong at 3993 and 4761. Conditions are marginal, so not the best call even if you’re experienced.

From Thursday the 9th onward, the outlook gets pretty grim. The swell just keeps pumping up to 13 ft to 16 ft but with strong cross-onshore winds from the ENE at 18 to 22 mph, and the energy gets very strong (10122 to 15492). That’s blown out, messy, and poor. There’s a real block of several days from Thursday the 9th all the way through to Monday the 13th with nothing recommended. The wind stays onshore or cross-onshore, often strong, and we see some tropical storm risks. Even when the swell drops back to 1 ft on Monday the 13th, the wind is onshore and the energy is weak at 17 to 23. Not worth it.

By Tuesday the 14th, the swell is back up to 10 ft from the SE, but the period is short (8 to 9 seconds) and the wind is onshore from the east. The energy is moderate to strong (979 to 1624), but conditions are poor to marginal. The same story runs through Wednesday the 15th. Then on Thursday the 16th, we get a massive 13 ft swell from the east with a period of 11 seconds and very strong energy at 5998. The notes say the swell is predicted to be too big for this break, and with the risk of thunderstorms and onshore wind, it’s a miss.

The final few days from Friday the 17th to Monday the 20th are all poor conditions with onshore or cross-onshore winds and messy seas. So, to sum it up: your one true standout is Tuesday the 7th of July, especially the afternoon glass-off at Yonabaru. Get it while it’s clean.

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.
