The Lowdown

Alright folks, Rusty here. The outlook for the next couple weeks is pretty bleak – I’ll call it like I see it. There’s no decent surf on offer until the very end of the run, so you’ve got a long stretch of flat or useless conditions ahead. The spot to watch is Yonabaru, a beginner-friendly break that usually gets some waves, but this period is a real test.

Water temp is 28°, right around normal, so it’s warm while you’re sitting on your board, waiting.

From right now through the 30th of July, it’s a dead zone. Swell is tiny – 0.5 ft to 1 ft – with weak energy readings (26 to 91), and the wind is mostly blowing onshore or cross-onshore, just chopping everything up. It’s garbage.

We get a small spark on the morning of the 31st of July with a light offshore wind and clean conditions, but the swell is only 1 ft. The energy is still low (91), and it’s just barely “surfable” – nothing to get stoked about.

The real deal shows up on the 2nd of August. Sunday afternoon is the big standout. You’ve got a 7 ft swell from the ESE with a super long 15-second period, and the energy is pumping at 1693. Wind is light and cross-offshore from the NNW, which means clean, open faces. But here’s the catch: that kind of long-period groundswell can be hard to ride at a beach break like Yonabaru – it tends to just close out. Still, for a skilled surfer, this is the best bet. The morning of the 3rd of August jumps to 10 ft, and by the afternoon it hits a massive 12 ft from the same ESE direction with a 15-second period and clean cross-offshore wind. The energy reading is insane at 4812. This is expert-only, no doubt about it – too big for anyone who doesn’t know what they’re doing. It’s heavy, powerful, and intimidating.

After that, it drops back to small, weak swells by the 4th and 5th of August. So your window is tight, right at the beginning of August, and it’s for the experienced crew.

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.
