The Lowdown
Alright, let’s get real about the next couple of weeks. I’ve stared at the charts until my eyes went crossed, and I gotta be straight with you: it’s gonna be a tough stretch for scoring any kind of decent wave. We’re looking at a long, flat, and messy run, so if you’re jonesing for a proper session, you might wanna find another hobby for a bit.
The only spot with any kind of nod is Corners. It’s a reef break that’s fairly consistent but it’s not exactly lining up for us. For the next week and a half, almost everything is a write-off. There’s some tiny swell showing, mostly around the 2ft mark, but the winds are all over the place. We get some clean windows on Saturday the 15th and Sunday the 16th, but the energy is weak, with the combined swell energy sitting around 100 to 130. That’s weak, marginal stuff, and the short 8-second period just doesn’t have any push to it. The water’s a touch cooler than average for this time of year, about 0.5°F off, so nothing crazy, but it’s not balmy either.
The morning of Sunday the 16th has a little pulse of S-SSW swell around 3ft at 8 seconds, but it’s crossed up with a 15 km/h SE wind. It’s clean-ish, but the lack of size and period just means it's not gonna be worth the paddle. The rest of that week is just poor, with the wind swinging around and chopping up whatever dribble is out there.
Then we get a bit of a tease. On Thursday the 20th, the afternoon shows a slightly better window. Swell bumps up to 3ft from the S with a 10-second period, and the energy jumps to 162. Still small, but that longer period is a hint of better things. The wind is a light cross-off from the E, so the surface might be okay. But then Friday the 21st rolls in with a 25 km/h WSW onshore wind and 4ft of S swell. The size is there, but it’s going to be a stormy, bumpy mess. For a more exposed reef like Corners, that’s not going to be pretty.
After that, it’s just a slow, sad fade. The swell drops off to nothing, the wind stays dicey, and the whole thing just looks like a write-off. There’s a brief moment around the 23rd with some 2ft SW swell at 10 seconds, but it’s crossed up with a NW wind. It’s just not there.
So, here’s the deal. The only two calls that even get a sniff are the Saturday afternoon (Aug 15) when it’s 2ft from the SW with a light offshore E wind – clean but tiny – and Thursday afternoon (Aug 20) which has a touch more size and period, but is still marginal. Honestly, if you’re an experienced surfer who can make something out of nothing on a reef, you might get a few grovelly ones. For everyone else, it’s a no-go. It’s a real bummer, but that’s the way it is. The conditions are just poor, with weak energy and bad winds dominating the whole window. We’ll see if the long-range models change their tune, but for now, I’d leave the board in the van and grab a coffee.
The waves are just too weak and inconsistent to even think about. It’s one of those blank runs that happens. Hang tight.

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.
