The Lowdown
Alright, Rusty here again, just in different numbers.
Look, I gotta be straight with you – the next couple of weeks here at Corners are looking flat. Real flat. We've got a solid 16-day window in front of us, but honestly, for the first ten days or so, there's just nothing doing. You're looking at a dry spell from now until around the 21st of September where the swell is basically non-existent or only showing tiny, weak 0.7ft to 1.0ft pulses. The combined wave energy is barely registering, often sitting at just 3 or zero. It's a tough stretch.
Now, from Monday the 23rd, things try to pick up, but it's ugly. We get a burst of wind from the NW, building into a gale that absolutely trashes the whole setup. The swell does bump up to 3.3ft on Monday the 23rd, but with near-gale cross-onshore winds at 37 mph, it’s a total mess – blown out and lumpy. That energy reading hits 113, but you wouldn't want to be out there. This pattern, with fresh to gale-force cross-shore winds, hangs around through the 25th. For a reef break that’s exposed, this isn't a paddle session; it's a kite surfer's dream with those strong, steady winds, and for us, it’s a hard pass.
The real glimmer, the only thing that gets me a little excited, is right at the very end of the forecast. Look at the 26th and 27th of September. The swell drops back to a tiny 1.3ft, but it shifts to a long-period groundswell from the SW at 12 seconds, with a combined energy of 45. That's a proper, clean pulse of energy. But the real beauty is the wind. On the morning of the 27th, it goes glassy. Absolutely flat calm. For a break like this, rare good conditions are everything. It’ll be tiny, clean waves, and with the light NNE breeze before the glass-off, crowds are likely as everyone tries to get a piece of that. It won't be big, but it might be the best we see in this entire stretch.

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.
