The Lowdown

Alright, Rusty here. Let’s chew the fat on what’s happening at Yonabaru for the next couple of weeks.

Honestly, it’s a bit of a bummer. The surf is tiny and weak for the first week, and when a little size finally comes, the wind turns it to garbage. There’s a long gap at the start where there’s just nothing to ride.

From Tuesday the 21st through Thursday the 24th, the swell is a measly 1ft to 2ft out of the east-northeast or east, with periods around 9 to 10 seconds. The combined wave energy is real low, between 27 and 52 – that’s barely a ripple. The wind is clean, even glassy on Thursday morning, but the waves are too small to bother with.

Friday the 25th stays small, with a little bump to 2ft and a short 7-second period, but the wind swings onshore from the east at 12 mph, messing things up. The energy is still weak at 71.

Then Saturday the 26th sees a spike in swell – around 6ft to 7ft from the southeast, with a 10-second period, and the combined energy jumps to 636-819. That’s a lot of power for a beach break, but the wind is howling onshore from the east-southeast at 12-16 mph. The setup is blown out, and honestly, this looks more interesting for kite surfing than a proper paddle session.

Sunday the 27th goes flat with zero recorded swell, and Monday the 28th is also flat until the afternoon, when a 4ft southeast swell comes in with a 9-second period and moderate energy of 266. The wind turns offshore from the west at 12 mph, so it’s clean. But Yonabaru is a beginner-friendly, fairly exposed spot, and that swell direction is from the east-southeast, not the optimum northeast. The conditions are still described as “very ordinary,” so it’s only a 1/10.

From Tuesday the 29th onward, it’s back to tiny, weak surf with poor conditions. The 30th and 31st offer nothing but knee-high slop with onshore or cross-offshore winds. The first week of August is a write-off, with strong to gale-force winds and messy, lumpy seas. The water temperature is about average for this time of year, so no surprises there.

The one standout, if you can call it that, is the afternoon of Monday the 28th. It’s the only time in the whole 16 days with a clean offshore wind and a bit of size, but it’s still a far cry from good. The swell is 4ft from the east-southeast, and for a break that prefers northeast, it’s not ideal. The energy is moderate at 266 (in brackets), and the period is short at 9 seconds, so the waves will be a bit crumbly. For a beginner spot, this is about the best you’ll get, but don’t expect any barrels.

Overall, this is a pretty flat and forgettable run for Yonabaru. The consistency is fairly consistent, but the quality is just not there. The second week is particularly grim, with onshore winds and tiny swell. If you’re desperate for a paddle, the 28th afternoon is your only real shot, but keep the expectations low.

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.
