The Lowdown
Alright folks, Rusty here. Let’s take a hard look at what’s coming up for Yonabaru over the next couple weeks. I’ll be straight with you – this stretch is a real bummer. We’ve got a long, dry run of poor surf conditions, and the only day that even sniffs at surfable is still pretty ordinary. The water’s sitting at 81°, which is a bit colder than usual for this time of year – about 3° below normal – so don’t expect that warm bath you might be used to.
From now through to the end of July, it’s mostly tiny, weak swell with cross-off or onshore winds. Saturday the 18th gives us a meagre 1 ft from the east at 10 seconds, and it’s just not worth paddling out. That pattern holds all the way through Sunday the 27th – heights never crack 3 ft, and the energy is feeble (27 to 427 on the combined scale). Winds are light to moderate, but the swell is too small and messy.

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.
