The Lowdown
Hey, Rusty here. Let's cut straight to it – this 16-day window for Yonabaru is a total bust. I'm not seeing a single session worth paddling out for. The whole stretch from Sunday 19 July through Monday 3 August is stuffed with poor surf conditions – tiny waves, weak energy, and even when the wind turns offshore or glassy, the swell just isn't there. The only flicker of something bigger comes around Monday 27 July and Tuesday 28 July, when a medium-period ESE swell pushes in, but it's paired with strong cross-shore winds (15–25 mph) that trash any chance of clean waves. The combined energy does hit 573–995, but that's all noise – the wave quality is rated marginal at best, and the swell direction (ESE) is way off the optimum NE that Yonabaru needs. That spot wants a good NE groundswell to light up, and we're getting nothing like it. There's a brief window on Wednesday 29 July with offshore winds and a dropping 4–4 ft ESE swell, but again, wrong direction and marginal conditions. For a beginner-friendly spot that's fairly consistent normally, this is a blank run. It's not unusual for this area to go quiet in summer, but still – disappointing. If you're desperate for a paddle, the mornings of 22–23 July have glassy conditions and tiny 1 ft E swell, but you'll be scratching for knee-high dribbles. My advice? Save your energy – forecasts can change, but right now there's nothing to get excited about. 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.
