Alright folks, Rusty here. Let's have a good hard look at what Yonabaru's got cooking for us over the coming weeks. Gotta be straight with you, the start of the period is a bit of a slow burner. We're looking at a few days of tiny, weak waves and mostly cross-off winds that won't do us any favours. It's gonna be a waiting game.
Right off the bat, Saturday the 4th and Sunday the 5th are pretty much a write-off. We're talking ankle-snappers at 2ft to 1ft from the ESE with a short period. The combined energy is weak (41), and with a cross-off breeze, it's just not worth suiting up. Monday the 6th sees a touch more life with the period jumping to 17 seconds overnight, but the swell is still tiny. The morning's got that long-period energy but only 1ft, and by the afternoon it's picking up to 2ft with a combined energy of 197. Still, "ordinary" is the word the charts are using, and I'm not arguing.
Now, Tuesday the 7th is where we finally get something to talk about. Tuesday morning, we've got glassy conditions, a 4ft SE groundswell with a solid 13-second period, and the combined energy is sitting at a moderate 422. That's clean, that's surfable. It's a beginner-friendly height, but the longer period means better-shaped waves. Then Tuesday afternoon, it gets even better. The swell bumps up to a very solid 5ft from the SE, the period stretches to a very long 17 seconds, and the energy jumps right up to 1036. Winds go light cross-off from the WNW. This is easily your best bet in the whole outlook. The water temp is 82°, which is about 1° below the norm, so pretty average for this time of year.
Wednesday the 8th is a different beast. The swell is way up, 10ft from the SE with an 18-second period. That's a powerful, long-period groundswell, and the energy is a strong 4969. This is expert territory for sure – too big for beginners. The problem is the wind. Morning is a cross-shore, but by afternoon it's turning cross-on from the NE, making it choppy and messy. For a point break or reef it'd be a dream, but at a fairly exposed beach setup like Yonabaru, that long-period swell might break a bit too straight. I'd say this window is more interesting for the kite crew than us paddle surfers.
From Thursday the 9th onwards, it's a total shut-down. We've got a risk of thunderstorms Thursday and Friday the 10th, with onshore winds screaming up to 31 mph. The swell vanishes into nothing, and the combined energy drops to zero. That nasty pattern of strong onshore winds and storms carries through the weekend and into the next week. There's a bit of a gap from July 9th through at least the end of the forecast window, with just tiny, useless waves and poor onshore wind.
In short, if you're keen, circle Tuesday July 7th on your calendar. The morning glass-off on the 4ft SE swell will be the cleanest, but the afternoon's 5ft SE groundswell with light cross-off winds is the real standout. The rest is a whole lot of nothing.
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.
