The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on offer for Yonabaru over the next couple of weeks.
Right off the bat, I gotta be honest with you – it’s a tough start. We’re looking at a pretty flat spell from now until the end of July. The first week is basically a write-off. There’s just no energy in the water. The combined swell energy is barely tickling the 30s (39) and the wind is mostly onshore or cross-onshore, keeping things messy. You’ll see a few clean, glassy windows on Thursday the 30th and Friday the 31st, but with tiny waves around 1 ft to 1 ft and a short period, it’s really just a paddle around. Not worth loading the boards for.
Then we hit a real dry gap. From Saturday the 1st of August through to Monday the 3rd, it’s almost completely flat, with the swell dropping to zero at times. Just a whole lot of nothing.
But hold on – things change in a big way starting Tuesday the 4th of August. A proper groundswell pushes in from the east, with a long period of 17 seconds. The swell height jumps to 4 ft and the combined energy rockets up to 816. That’s a solid, moderate energy. The wind is light and cross-offshore, so the conditions are clean. This is the standout window. Yonabaru is a fairly exposed beginner spot, and with a 4 ft east swell, it’s going to be right in the sweet spot for a fun, longboard day. The water temp is about average for this time of year, nothing weird.
The swell holds through Wednesday the 5th and into Thursday the 6th, building a touch to 5 ft. The period stays long, over 15 seconds, so this is a proper groundswell with real push. Thursday morning looks absolutely glassy with zero wind and 5 ft of east swell – that’s about as good as it gets for a setup like this. The combined energy is over 1100 (1138), strong stuff. Keep in mind, 5 ft is getting a bit solid for beginners, but it’s still manageable. The long period means it’ll be a bit straighter on the beach, but it’ll hold up well.
The quality starts to fade from Friday the 7th as the wind swings onshore in the afternoon, and by Saturday the 8th the cross-onshore chop ruins it. The swell drops off quickly after that, and by the second week we’re looking at small, messy leftovers with no real standouts. The best of the run is definitely Tuesday the 4th through to Thursday the 6th.
So, if you’ve been itching for a wave, hold tight. The 4th, 5th, and 6th of August are your days. Don’t bother before that.
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.
