The Lowdown

Alright, Rusty here. Let’s be straight with you about what’s on offer for Yonabaru over the next couple of weeks.

Truth is, we’re looking at a pretty flat and quiet run for a good while. The first few days, from Friday the 17th right through to the end of the following week, you’re going to be staring at tiny, weak waves. We’re talking ankle-biters around 1ft to 1ft from the east, with a short period around 9 to 10 seconds. The combined wave energy is barely registering (29 to 30) – it’s just not enough to get excited about. Winds are mostly cross-off or glassy, so the water will look clean, but there’s just no push. The water temperature is about average for the time of year, so no surprises there.

The first real glimmer of something happens on Thursday the 23rd. On the morning, we get a little bump in the swell to 2ft from the east, with the period stretching to 11 seconds. The energy jumps to 82, which is still weak, but it’s the best we’ve seen. With glassy, offshore conditions, it’ll be clean and might give a log or a longboard a few little fun ones. It’s still beginner-friendly at that size. Keep in mind, the break is fairly exposed to the east, and the optimum swell direction is from the northeast, so we’re not quite getting the ideal angle.

After that, it’s back to small stuff for a few days, with more onshore winds kicking in from the 26th. The end of the month sees a bit more size, with swell building to 3ft and then 4ft around the 28th and 29th, but the trade winds are howling from the southeast and east, making it a messy, choppy affair. The energy ramps up (451 on the 29th morning), but with cross-onshore winds and a short-ish period, it’s just not going to be clean. This setup looks more interesting for kite surfing than paddle surfing.

The very last day, Saturday the 1st of August, shows a cleaner pulse of 3ft from the southeast with a cross-off wind, but the period is a short 8 seconds, so it’ll be a bit wobble and weak. Still, it’s the cleanest of the bigger stuff.

If I had to pick the one standout, it’s the Thursday morning the 23rd at Yonabaru. That’s your best bet for a clean, glassy session on tiny waves. Everything else is either flat or blown out. Don’t hold your breath for the second week – it’s all stormy and messy.

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.
