Table - best surf conditions forecast for Yonabaru over the next 16 days.
Alright, let me level with ya. Looking at Yonabaru, it’s a pretty bleak run for the next couple of weeks. There’s a real dry spell on the cards here, and the truth is, there isn’t a single standout session to get excited about. It’s just flat, blown out, or messy right the way through.
The forecast kicks off Saturday, 11 July, but it’s a write-off – severe gale cross-onshore winds at 47 mph, totally blown out, no swell to speak of. That pattern holds through the weekend and into Monday; even when we see a tiny bit of energy on Monday morning, it’s a weak 0.7 ft from the east with a period of 9 seconds, cross-onshore at 16 mph, and energy reading just 14 – barely a ripple.
We get a slight improvement Tuesday and Wednesday, but it’s still tiny. Wednesday afternoon sees a bit of a cleaner window with a cross-offshore breeze and a 1.0 ft east swell (period 11 seconds), but that’s for ankle-biters only. Thursday morning, 16 July, we finally get a glassy session – wind drops to 3 mph, the water goes smooth, but the swell is still only 1 ft from the east-southeast at 9 seconds, energy 26. The water temp is about average for the time of year here. It’d be a fun little paddle on a foamie, but not worth chasing for any real waves.
Then we get a big spike Sunday, 19 July, but it’s a mess. That morning shows a 10 ft swell from the southeast with 9-second period – that’s moderate energy (1370) – but the wind is onshore at 16 mph. That’s a washing machine, not a surfable wave. Over 8 ft and onshore? Only for masochists. That swell drops fast, and by Monday afternoon it’s back down to 5 ft, still onshore.
The final few days of the outlook show a few cleaner moments – Saturday 25 July morning with a cross-offshore breeze and 1 ft east-southeast swell – but it’s all tiny and weak. Honestly, there are no sessions here that qualify as a proper surf recommendation. It’s a long gap of poor conditions with nothing to recommend. For a spot like Yonabaru, a blank run like this is more normal for the area when the winds don’t line up. Don’t hold your breath – forecasts can change, but right now, leave the board at home.

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.
