The Lowdown

Alright, Rusty here. Let’s break down what’s on the menu for Yonabaru over the next couple of weeks. Look, I won’t sugarcoat it – it’s been a dry spell, and it’s gonna stay that way for a while, but there’s a tiny glimmer for the patient surfer.

Right now and for the next few days, the surf is pretty much non-existent. The wind is coming from the east and southeast, blowing onshore or cross-onshore at 10 to 25 mph, and the swell is tiny – we’re talking 1ft to 3ft with combined wave energy values between 29 and 127, which is weak. The water temp is about average for the time of year. Conditions are just poor, with nothing rideable. There’s a big pulse of swell coming through on August 25th – we’re looking at 12ft to 13ft from the east with a very long period of 16 to 17 seconds, and combined energy around 8000 to 8900, which is very strong. But honestly, that’s way too much for this beginner-friendly break. That’s expert-only territory, and the reports say it’s just too big for this spot. The wind is cross-shore, but still, not worth it.

The rest of the week through the end of August and into early September is more of the same: onshore winds, mostly poor surf conditions, and inconsistent small waves. There’s a gap of several days with no real recommendations. You’ll see some 6ft to 8ft swell on the 31st, 1st, and 2nd, but the wind is onshore or cross-onshore, and the period is short to moderate (8 to 10 seconds), so it looks choppy and messy. Combined energy gets up into the 583 to 1238 range for some, which is moderate energy, but the wind kills it. There’s a brief moment on September 2nd where we get a 10ft east-southeast swell with a gentle cross-shore breeze and moderate wave energy (1373), but it’s still only a 2 out of 10 on the forecast. Not enough to get excited about.

The only real stand-out in this whole 16-day window comes much later, on September 5th. Saturday morning is our best bet. The swell drops to a manageable 3ft from the east with a 9-second period – not huge, but the wind turns offshore from the west at 15 mph. That offshore wind is a big deal for this break, it’ll clean things right up. The combined energy is moderate at 311, and the overall forecast is good. This is the one to aim for. The break is fairly consistent, and with the right tide, it could be a fun little session, especially for beginners looking for clean, smaller waves just after that big winter swell passes. If you’ve been waiting for something, this is your window.

Remember, Yonabaru can be a bit inconsistent for long periods, so a run like this isn’t totally unusual. Keep an eye on the sky, because forecasts can change.

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.
