The Lowdown
Alright, Rusty here again. Let’s talk it through in feet and miles per hour.
Right now, Yonabaru is looking flat and pretty dull. There’s a big gap from today, starting Tuesday the 14th, all the way through until around Monday the 27th of July with nothing worth paddling for. Most days are showing ankle-snappers, 1ft or so, with combined swell energy stuck in the teens and 30s – real weak. Winds are all over the shop, cross-shore or onshore, keeping things choppy or just dead.
The first flicker of hope comes on Monday the 27th of July. Monday morning is still tiny, but Monday afternoon we get a pulse of about 3ft from the SE with a period of 13 seconds – that’s a long-period groundswell starting to push, and the combined energy jumps to 208 (moderate). Winds go glassy, so it’s a good sign.
The real standout is Tuesday the 28th of July. Tuesday morning we’ve got 6ft from the ESE with a 10-second period and combined energy at 661 – strong. Winds glassy. Tuesday afternoon it builds to 6ft from the ESE, period still 10 seconds, and energy hits 698 – very strong. Winds turn offshore from the WSW at just 6 mph, so it’ll be clean. This is the pick of the whole run. The swell direction is a bit east of the optimum NE, but with that size and offshore wind, it’s still a cracking day. That 6ft is getting into expert territory though, so not for beginners. Water temp is about 82°F, which is actually 2°F cooler than average – a bit on the cool side for July.
Wednesday the 29th of July morning still has 5ft from the ESE with a 9-second period, energy at 329 (moderate), and light offshore wind. Another good session, but smaller. By Wednesday afternoon it drops back to nothing.
So, if you’re waiting on waves, lock in Tuesday the 28th of July. That’s the day to be in the water. The rest is a slow grind.
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.
