The Lowdown
Right then, let’s have a look at what’s on offer for the next couple of weeks. To be honest, it’s a pretty grim outlook for the region. The first solid stretch of surfable waves is a long way off, and even then, the conditions are a mess. We’ve got a huge gap of nothing from now until the 27th of July, with nothing but tiny, poor surf that’s not worth paddling out for.
The first real pulse of energy shows up on the 27th of July, but it’s not a pretty picture. Swell climbs to 2ft, but it’s coming from the SE with a cross-onshore wind from the NNE at 6 mph. The combined energy is moderate at 116, but with the wind messing it up, it’s all a bit of a washout. That afternoon, it gets a little bigger at 3ft from the SE, but the wind swings onshore from the ENE at 12 mph, making it choppy and messy. Not a day to get excited about.
The standout, if you can call it that, is the 28th of July. The swell jumps up to 5ft from the SE, with a very long period of 15 seconds – that’s groundswell with plenty of energy (968). It’s a powerful swell, but it’s coming with a cross-onshore wind from the NE at 12 mph. The water temperature is a bit colder than usual at 81°, which is about 3° below average for the time of year. For a point break or reef, that long period could be a treat, but here at a beach break, it might just break too straight. The afternoon sees the swell hit 7ft from the SE, period 14 seconds, and the energy jumps to 1718 – that’s strong. But the wind is still cross-onshore at 16 mph, so it’s going to be a battle. This is really only for the experienced crew, and even then, the wind is a killer.
Then, on the 29th of July, it gets wild. The swell is 12ft from the SE, with a very long period of 14 seconds and a massive 5357 energy. But the wind is a fresh cross-shore from the N at 22 mph, with a risk of thunderstorms. That’s a big, lumpy, dangerous mess. By the afternoon, it’s 13ft of SE swell with the wind up to 31 mph. That’s not for paddle surfing – that’s kiteboarding territory if you’re brave enough. The 30th of July is worse, with 15ft of NW swell and a near gale cross-onshore at 34 mph, with moderate rain. The energy is 5434, but it’s completely blown out.
So, what’s the call? The 28th of July morning is the best on offer, but it’s not good. The swell is there, but the wind is ruining it. The rest of the 16-day window is a write-off. It’s a poor run, but it’s not unheard of for this area. Forecasts can change, so keep an eye on it, but right now, I’d save your energy.

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.
