The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s cooking for the next couple of weeks.

Honestly, I gotta be straight with you – this stretch is a tough one. We’re looking at a long, dry spell with next to nothing on offer for the vast majority of the period. The first solid hint of anything surfable doesn’t pop up until the 4th of August, so we’re talking about a gap of about two weeks where you can pretty much leave the boards in the shed.

The water is sitting at 82°, which is a bit colder than normal for this time of year, just a heads-up if you’re sensitive to that.

From the 20th of July right through to the 3rd of August, the wave comment is “poor surf conditions” across the board. It’s a real bummer. Swell heights are tiny, mostly 1ft to 2ft, and the wind is all over the place – cross-off, onshore, even some glassy conditions on the 23rd, but with no swell to work with, it’s a flat calm. The combined energy is weak, with values mostly below 50. There’s nothing to get excited about at Yonabaru.

Now, as we slide into the first week of August, there’s a tiny flicker of hope. The 4th of August is where things get a little interesting. Tuesday afternoon shows a knee-high 2ft swell from the ESE, with a period of 14 seconds – that’s a proper long-period groundswell. The combined energy jumps to 247 (moderate wave energy), and we’ve got a light cross-off breeze from the NNW. That’s about as clean as it gets for this spot. The wave comment says “surfable waves but very ordinary conditions” – it’s not going to be world-class, but it’s the only game in town. The swell direction (ESE) doesn’t perfectly match the recommended optimum (NE) for Yonabaru, which is a bit of a shame, but it’s still something.

Given the long period, this swell will be better shaped than the usual dribble, but it might break a bit straight at the beach. The crowd factor is “sometimes” here, so you might bump into a few others who are equally desperate for a paddle. This is the only standout, and it’s a weak one, so keep your expectations low.

So, to sum it up: You’ve got a long wait for a tiny, mediocre window on the 4th of August. It’s not a total write-off, but it’s close. That’s the reality of it.

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.
