The Lowdown

Alright folks, Rusty here. Let’s talk about what’s cookin’ for this stretch. We’re looking at Yonabaru—a fairly exposed beginner’s spot that’s usually pretty consistent. Right now, the water is sitting at a toasty 87°, which is a touch warmer than normal for this time of year, so you’ll be nice and comfortable.

We’ve got a bit of a slow start, but it builds. Sunday afternoon kicks things off with a tiny 2 ft ESE groundswell, period way up at 17 seconds, and glassy conditions with a light northerly breeze. Combined energy is weak at 186, but for a beginner-friendly wave, it’s clean and rideable.

Monday morning sees the swell bump to 3 ft from ESE, period still long at 15 seconds, and a moderate 399 energy reading. The wind goes cross-shore though, so it’s a bit choppy. Monday afternoon gets a little better—4 ft ESE swell, 16-second period, 644 energy, with a light cross breeze. Nothing to write home about, but surfable.

Tuesday brings building swell—5 ft to 5 ft from the E, 17-second period, but we’ve got some risk of thunderstorms and onshore or cross-onshore winds. Energy jumps to 1389–1555, so there’s some push, but the conditions are marginal. This is getting a bit bigger for beginners.

Wednesday is the real ramp-up. Morning sees 8 ft E swell, 18-second period, 3624 energy—strong. Winds are cross-onshore, so it’s choppy. By afternoon it’s 8 ft, still E, 18 seconds, and energy hits 4595. Still cross-onshore and choppy. This is getting into expert territory, but the wind’s messy.

Thursday morning is a beast—15 ft from the E, 18 seconds, energy a massive 12894. Wind is cross-shore at 22 mph, so it’s lumpy. The swell is just too big for this break. Same story Thursday afternoon: 15 ft, 18 seconds, 14803 energy, but winds go cross-offshore and it cleans up. Still, it’s expert-only.

Friday and Saturday are extreme. Friday morning has 16 ft E swell, 18 seconds, 23016 energy with gale-force cross-offshore winds. Friday afternoon sees 25 ft from the NNW, only 12-second period, but energy is 24747—clean but absolutely massive. Saturday morning is the peak: 26 ft NW swell, 13 seconds, 25199 energy, with storm-force cross-offshore winds. This is not for paddle surfing—this is for big-wave chargers or maybe kite surfers.

After that, the swell drops hard. Saturday afternoon goes to 8 ft from the NE, 13 seconds, 2798 energy, but it’s gale-force offshore—impossible to paddle into. Sunday through Tuesday are tiny—1 ft to 3 ft, weak energy, but winds stay cross-offshore so it’s clean. Hardly anything to ride.

Wednesday morning the 12th shows a bit of life: 4 ft from the ENE, 13 seconds, 802 energy, with light cross-offshore winds and clean conditions. That’s a bright spot, but it’s just a morning window. The rest of the week stays small and weak, with a few glassy moments on the 16th (2 ft–2 ft E swell, 10-second period, 74–100 energy).

If I had to pick the best on offer, I’d say the standout is Wednesday morning the 12th of August—4 ft ENE swell, 13-second period, clean with light cross-offshore wind. It’s not huge, but it’s the most user-friendly wave in the whole run. The earlier Sunday afternoon glass-off is nice for a tiny wave, too. For the rest... it’s either too big, too windy, or too flat.

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.
