The Lowdown
Alright folks, Rusty here. Gotta be straight with you on this one – it’s a tough stretch at Corners. We’re looking at a 16-day window here, but it’s a long, slow burn before anything really lights up, so let’s walk through it.
The next week and a half is pretty much a write-off. We’ve got a massive gap from the start all the way through Thursday, August 14th, with absolutely nothing worth paddling out for. The swell is tiny, if it’s even there. On Sunday morning, August 2nd, we’re looking at a weak 1-foot swell from the southeast with a 9-second period – the combined energy is a meager 13, which is basically nothing. The wind is cross-off from the north, so the water’s clean, but it’s just not enough push. It stays like that, flat and weak, for days. By Wednesday, August 5th, the wind kicks up to 18 mph, and then we get a proper storm. Friday, August 7th, we’re talking hurricane-force winds and heavy rain – steer clear of the ocean entirely.
Then, on the afternoon of Friday, August 7th, things get a little wild but not in a good way for us. The swell jumps to 12 feet from the northwest with a 12-second period, and the combined energy rockets to 5009. But the wind is a screaming 31 mph offshore from the east. That’s a near gale offshore – you’d be fighting for your life just to get out, and the paddle-in would be brutal. If you’re a kiter, that setup might be interesting, but for a surfer, it’s a no-go. The next day, Saturday, August 8th, is when it gets proper scary. The morning shows a 31-foot swell from the south with a 15-second period, and the energy is a monstrous 38568. The wind is storm force and cross-shore – it’s a total mess, and the swell is way too big for this break. The afternoon drops to 20 feet, still too big and windy.
Sunday, August 9th, through to Thursday, August 14th, sees the swell dropping but the wind stays onshore or cross-shore, keeping the surf blown out. We’re still looking at messy, poor conditions with waves in the 6-10 foot range but horrid winds.
Now, here’s where it finally gets interesting for us. The standout window is the weekend of August 15th and 16th. On the afternoon of Saturday, August 15th, we get a clean window. The swell is a manageable 5 feet from the SSW with a 10-second period. The combined energy is 468 – moderate, but solid. Best of all, the wind is a gentle 9 mph offshore from the east. That’s the big one. The forecast says “expect good surf conditions,” and I’m feeling it. That 5-foot groundswell with clean offshore wind will make for some fun, shapey waves at Corners. It’s not huge, but it’s clean and rideable – easily the best of the whole run.
Sunday, August 16th, keeps the momentum. Both morning and afternoon offer 5-foot to 5-foot swell from the SSW, with a 10-second period. The wind is a cross-off from the NE at 12-15 mph, keeping the faces clean. The energy is in the 400-500 range, and while it’s not a giant day, it’s consistent and good for a long session. Monday, August 17th, looks promising too, with 4-foot swell and a moderate offshore from the ENE – the wind is 15 mph offshore, which is a bit strong but still clean.
So here’s the call: Don’t waste your time before the 15th. The surf is mostly flat, or too big and blown out. The true standout is the afternoon of Saturday, August 15th – that gentle offshore wind on a 5-foot SSW groundswell will be the cleanest, most fun waves of the entire forecast. Sunday the 16th is a close second, with cleaner conditions than the rest of the week. Crowds at Corners? They’re “often” around, so on a day that good, expect a few locals out. But for this spot, that’s the one to aim for.
This is Rusty, signing off.

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.
