Updates in hr min s Forecast update imminent
Alright, Rusty here, let's take a look at what’s on offer for your local surf, Yonabaru. The immediate forecast looks bleak but there's a light at the end of the tunnel for the patient surfer.
We’re starting off with nothing special on the table. Tuesday afternoon the 7th of July might look inviting with chest-high 1ft swell from the southeast, a very long 16 second period, and glassy offshore wind from the northwest. The combined energy is moderate (792). However, the overall call is for "expect very good surf conditions" but the rating just isn't high enough to call it a standout for me. It's a tease, really.
Then the wheels fall off. From Wednesday the 8th onward, things turn to junk. The wind swings onshore and builds quickly. By Thursday the 9th, we’re looking at a raw 13ft to 15ft stormy mess with gale-force cross-on winds, making it a full-on no-go zone. Combined energy shoots way up (7700 to 9661), but that's just a wall of whitewater. A total write-off for paddle surfing; that setup looks more interesting for kite surfing. This poor pattern continues right through until about Friday the 17th of July, with onshore winds, storm risks, and messy conditions dominating. That’s a solid 8-9 day gap with no decent surf.
Finally, we see a glimmer of hope. On the morning of Friday the 17th, the wind turns offshore from the west-northwest, and although the swell is only 4ft from the east with a modest 10 second period, the conditions turn clean. The combined energy is low (262), but with a gentle offshore breeze cleaning it up, it's surfable. By Wednesday the 22nd of July, we get our real standout. The morning shows a solid 6ft swell from the east-northeast, with a moderate offshore wind from the west cleaning it up nicely. The combined energy is moderate (526) and the forecast calls for "expect good surf conditions". With a period of 9 seconds, it should offer some push without being too fat. This day is the one to wait for. It's not huge, but with clean conditions and that offshore flow, Yonabaru will have some fun, rippable waves.
So hold tight. This stretch is a write-off until the 17th, and the real gem is the 22nd. Don't bother paddling out before then unless you want to get worked or watch the kite surfers have a field day.
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.
