The Lowdown

Imperial Version

Alright, folks, Rusty here. Let's have a look at what's on the cards for the local waters.

We’re looking at a bit of a rough start here, to be honest. The first call for a wave is Monday morning, 3rd of August, at Yonabaru. It’s a beginner-friendly spot, and we’ve got a small 3ft swell rolling in from the ESE with a long period of 15 seconds. The water’s nice and warm, sitting at 87°, which is a touch warmer than normal for this time of year. The wind is a gentle cross-shore, but the energy is weak (408) and the forecast is marginal. It’s not the best, but it’s a start.

Monday afternoon sees a slight bump to 4ft, the period stretches to 16 seconds, and the energy picks up (636). Still, it’s a marginal call.

Tuesday, the 4th, things get a bit more interesting with a risk of thunderstorms. The morning swell hits 5ft from the E, with a 17-second period, and the energy climbs into the moderate range (1389). The wind is light and cross-onshore, so a bit of chop. The afternoon bumps up to 5ft and more energy (1555), but the wind turns onshore, messing things up.

Wednesday the 5th is a write-off. The swell builds to 8ft in the morning and 8ft in the afternoon, but the wind is a cross-onshore mess, making it choppy and poor. The energy is strong (3259 and 4323), but the quality is just no good.

Now, Thursday the 6th is where it gets wild. The swell jumps to a massive 15ft in the morning and 16ft in the afternoon, both from the E with an 18-second period. The wind is a clean, cross-offshore breeze, and the energy is staggering (13426 and 15120). The file says it’s too big for this break, and I’d agree. This is big, powerful, heavy groundswell. For a beginner break, this is dangerous and only for the most experienced chargers. The period is over 15 seconds, so look for it to barrel at reefs and points, but at a beach break like this, it’s going to be a close-out. The water will be a washing machine.

Friday the 7th is even more extreme. The swell is 23ft and 26ft, from the NW, with a violent storm-force wind. The energy is off the charts (20186 and 28971). This is a full-on storm, not for surfing. It’s a kite-surfing set-up if you’re brave, but for paddle surfing, it’s a hard no.

The swell drops fast after that. Saturday the 8th has a small 3ft from the NNE with a 12-second period, and clean offshore wind, but the energy is weak (418). The forecast is marginal. Sunday the 9th is a total mess with violent storm-force winds and tiny waves, and the whole of the following week is a write-off. The wind is either cross-shore or onshore, and the swell is tiny, with weak energy. There’s a flicker of hope on the morning of Thursday the 13th, with a glassy 3ft wave from the E, but it’s ordinary. The best on offer here is the massive swell on Thursday the 6th, but it’s a total expert-only, dangerous beast. For the average surfer, there’s nothing to get excited about for a solid week and a half after that.

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.
