Alright folks, Rusty here. Let's be straight with you – the next couple of weeks in the Yonabaru area are looking flat, plain and simple. There’s no decent swell on the cards, and the few tiny bumps we do see are going to be messed up by onshore winds. It’s a tough run for paddle surfing, but let’s break down exactly what’s happening.
Right now, and for the rest of this week, we’ve got almost nothing to work with. Swell heights are stuck around 0.7 ft to 1 ft, with combined wave energy barely ticking over (21). That’s weak, gutless stuff. Winds are mostly cross or cross-off from the south and southwest, which is okay, but there’s just no power in the water. The water temp is sitting at 84 °F, which is bang on average for this time of year, so at least you won’t be cold while you’re floating around doing nothing.
After a few more days of tiny, clean-looking but completely underpowered conditions, the pattern shifts around July 23rd. The swell starts to nudge up to 2 ft, with the energy climbing into the 80s – still weak, but a little more push. Problem is, the wind turns onshore from the east and stays that way through to July 28th. That stiff onshore breeze is going to chop up any hope of a clean face. The swell direction is almost exclusively from the east, which is cross-onshore for Yonabaru’s setup. This is shaping up as a more interesting window for kite surfing than for paddle surfing, honestly.
There’s a brief uptick right at the very end of the window, around July 26th. Swell height hits 3 ft with the period stretching to 11 seconds, and energy bumps up to 143 – that’s moderate energy, finally. But again, the wind is smashing onshore at 12 mph from the east. It’ll be a choppy, messy affair, not the clean lines we’re after.
The long and short of it is this: there are no standouts, no hidden gems to chase. The whole 16-day forecast is a write-off for surf. That’s just how it goes here sometimes, forecasts can change, but right now, leave the board at home.
Yours, 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.
