The Lowdown
Alright folks, Rusty here. Let’s take a look at what’s cookin’ for the next couple of weeks at Corners. We’ve got a rough start, but there’s a little light at the end of the tunnel.
The forecast opens with a proper beating. A massive, powerful SSW swell is hammering the coast, with combined energy readings up in the 14024 (moderate wave energy) range, but it’s coming with a nasty cross-shore gale. The first few days are a total loss. Saturday the 8th and Sunday the 9th are howling with severe gale and gale force winds, whipping up big, messy, dangerous waves. You’re looking at 21 ft to 23 ft surf – that’s expert-only territory, and even then, it’s ugly. The wind doesn’t let up enough to even call it surfable until Monday the 10th, but it’s still cross-shore and lumpy with 8 ft waves. The whole first week is a fight against strong to moderate cross-shore winds, keeping the ocean choppy and closed out. It’s looking more like a kite-surfing show than a paddle session.
We finally get a break from the wind on Thursday the 13th. The wind swings light offshore from the NE at around 10 km/h (6 mph), and the swell drops to a more manageable 5 ft from the SSW. The combined energy is down to 322 (weak wave energy), but the conditions turn clean. This is the first real window of decent surf. The morning of Thursday the 13th is the standout of the whole outlook. Light offshore breeze, clean 5 ft SSW swell with a 9-second period. It’s not huge, but it’s the best combo of size and glassy conditions we’ll see. The afternoon stays clean, though a touch smaller at 3 ft.
The clean conditions hold into Friday the 14th, with a light cross-offshore breeze and 4 ft SSW swell in the morning. It’s surfable, but not as good as Thursday. Saturday the 15th is also looking promising, with a clean morning of 5 ft SSW swell and a light ESE cross-offshore wind. The real treat is Saturday afternoon, when the wind drops to glassy, with 4 ft SSW swell. That’s a chance for some smooth, peeling waves.
After that, the consistency drops off. From Sunday the 16th onward, the swell is small, mostly 4 ft or less, and the winds start to get a bit stronger again. The offshore winds remain, but the energy fades. By the 18th and 19th, the wind is howling offshore at 40-45 km/h (25-28 mph) from the east, which cleans the face but makes it a real battle to get out and paddle into the tiny 1 ft to 2 ft waves. The last week is a bit of a desert, with very small surf and strong winds, until the 22nd of August brings a brief pulse of 3 ft SE swell with a very short 7-second period. It’s clean, but the period is short and weak.
Overall, the best bet is to point your board at Thursday the 13th and Saturday the 15th for the cleanest, most user-friendly waves. The rest of the time, you’ll be fighting the wind or the lack of swell.
Rusty.

Information about the Corners Surf forecast
The above surf forecast table for Corners provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Corners can be found by selecting the local surf guide option on the grey menu. Our Corners 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 (Corners) 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 Corners 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.
Corners is 5 km (3 miles) from Misato. If you plan a holiday in Okinawa, look for hotels and other accommodation in Misato. Misato has rooms for a wide range of budgets as well as car hire and transport links.
