The Lowdown

Alright, let’s get into it. The long-range charts are showing a big pulse of energy coming our way, but the early part of the window is pretty quiet. We’ve got a few days of nothing worthwhile before things get interesting, and then it looks like we’re going to get absolutely smashed by a serious groundswell. The main event is a standout, but it’s not for the faint of heart.

The first real call is for Yonabaru on Friday, August 7th. The swell is coming in from the east with a solid 18ft of height and a long 17-second period. That’s a massive, powerful groundswell with a huge amount of energy behind it – we’re talking a combined energy of 26884, which is some serious water moving around. The wind is cross-offshore from the NNW, but it’s howling at 50 mph, which is severe gale force. Even though the conditions are clean, this is a lot of juice for a fairly exposed beginner spot. The swell is predicted to be too big for this break, and honestly, with that kind of wind and size, this is more of a cautionary tale than a green light. The swell direction is also a bit off from the break’s optimum, which is from the NE, so it won’t be lining up perfectly.

After that initial pulse, the weekend gets messy. The wind swings around to the southwest and it’s blowing a violent storm force, but the swell drops right off. That’s a dead period for any kind of surfing. The swell tries to rebuild on Monday, August 10th, but it’s weak and the wind is still up, making it a poor call.

The next noteworthy window is the following week, but it’s pretty ordinary. The surf is small, inconsistent, and the energy is weak. There’s a small window on Wednesday morning, August 12th, with a little 3ft swell from the NW, but it’s just not doing anything for us. The water temperature is running about average for this time of year, so no need for a thicker suit.

Honestly, the standout is that Friday, but it’s a “look but don’t paddle” kind of day. The bigger issue is that after that, the models just go flat. We’re looking at days of waist-high slop and onshore wind, with almost no energy at all. The combined energy readings drop into the low hundreds and even double digits, which is a sign of a very quiet stretch. For a spot that’s fairly consistent, this is a bit of a bummer, but it happens. The forecast for the second week is a long, flat run, so don’t get your hopes up about scoring anything decent.

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.
