Alright folks, Rusty here. Let’s have a look at what’s cookin’ for the next couple of weeks.
Right off the bat, I gotta be straight with you – the forecast is pretty grim. We’re looking at a long stretch of nothing special. The first recommendation doesn’t even pop up until the 12th of July, and even then, it’s barely a whisper. For the first few days, from Sunday the 12th through to the 18th, we’ve got next to no energy. The combined swell energy is sitting in the weak zone, mostly under 50 (29-52), with tiny 1ft to 2ft waves. The wind is mostly cross or cross-on, making it choppy and lumpy. Not worth paddling out for.
There’s a bit of a silver lining on the 15th and 16th. The wind swings cross-offshore and the morning sessions look clean, with a little 1ft to 1ft bump from the SE. The period stretches to 11 seconds on the 15th, giving it a hint of groundswell shape, but it’s still just too small to get excited about. For a beginner at Yonabaru, it’s ankle-to-knee high at best, and the water temperature is about average for the time of year.
Things start to look a little more interesting on the 19th of July. The swell picks up to 3ft from the east, and the combined energy jumps to 177 – that’s moderate energy. The wind is light onshore, but it’s onshore. The 20th and 21st see the swell building to 5ft, with energy readings in the 340s to 430s. That’s significant power for this spot. But here’s the catch – the wind is a solid onshore breeze from the east at 12-15 mph, and the period is short, around 8 to 9 seconds. That combo is going to make for a lumpy, wind-affected mess at the beach. The setup looks more interesting for kite surfing than paddle surfing.
The standout window, if you can call it that, is the 23rd of July. The swell is 3ft to 5ft from the east-southeast, with a better period of 10 seconds. The wind is a gentle cross-onshore, and the energy is solid (212-380). It’s not perfect, but it’s the best we’ve got. For a fairly consistent break like Yonabaru, this is your best bet, but the onshore wind will keep it bumpy. The 24th drops off a bit, and by the 25th and 26th, we’re back to tiny, weak waves with energy under 100. The 27th has a little 2ft bump with an 11-second period, but the cross-onshore wind spoils it.
Bottom line: a long, quiet stretch with a brief pulse of size around the 20th to 23rd, but the wind is never on your side. The 23rd is the pick of a poor bunch, but don’t expect any gems.

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.
