The Lowdown

Alright folks, Rusty here. Let's have a look at what's on the table for our stretch of coast.

Honestly, for the next week and a half, it’s looking pretty grim. We’re staring down a long, flat spell with nothing worth paddling out for. The wind is a mess, mostly cross-onshore or worse, and the swell is tiny with weak energy. There's a real dry spell from now until around the 19th of August, with barely a ripple to get excited about.

The one bright spot on the horizon, and it’s a distant one, is the end of the third week. Things start to rumble back to life around Thursday the 21st of August. The swell builds quickly, and by the Friday morning the 22nd, we’re looking at a solid 7ft of swell from the E. The energy is ramping up big time, with a combined energy reading of 663 (moderate). By Friday afternoon, it’s pumping with 10ft from the ESE and a period of 11 seconds, packing a whopping 1789 in energy (strong). That is serious power.

But here’s the catch, and it’s a big one. This is all aimed at Yonabaru, a fairly exposed beginner spot. When you get waves over 8ft, that’s expert territory, and this swell peaks right in that zone. The wind is howling onshore or cross-onshore at 18-25 mph, turning it into a washing machine. For a beach break, with that much wind and power, it’s going to be a messy, choppy mess. Honestly, that setup looks way more interesting for kite surfing than paddle surfing. The water temp is sitting at a warm 86°, which is a touch warmer than normal for the time of year, but you won’t be feeling it in that wind.

So, the takeaway? We’ve got a whole lot of nothing, then a big, wind-affected pulse of swell that’s going to be too wild for most. The best on offer is technically that Friday the 22nd and Saturday the 23rd, but it’s an expert-only, windy, and messy proposition. Keep your expectations low, and maybe give this one a miss unless you're a glutton for punishment and have a kite.

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.
