The Lowdown
Alright, Rusty here. Let’s be straight with you about this stretch. It ain’t looking flash.
We’ve got a long gap of flat, frustrated days ahead, so don’t bother waxing up just yet. From now right through until the 25th of September, you’re looking at mostly nothing. A few tiny, weak pulses, but honestly, they’re not worth paddling for. The wind is often light and clean or offshore, which is a tease, but there’s no power behind it. The first real chance of anything doesn’t show until the last days of the month, so you’ve got over a week and a half to find something else to do.
Corners is the only break to talk about here. A reef setup that’s fairly consistent and exposed to the SW, but it’s an advanced spot, so keep that in mind.
For the first week-plus, it’s a desert. Swell energy is zero or nearly zero, just some 0.3 ft to 1.0 ft dribble. On Monday the 14th and Tuesday the 15th we get clear skies and light offshore breeze (6 mph) but no swell to work with. Wednesday the 16th and Thursday the 17th? Same story. Light winds, clean conditions, zero surf. Friday the 18th and Saturday the 19th see a tiny bump of 1.0 ft from the south with a weak period of 8 seconds, giving combined energy of just 12 to 22 (truly weak), but the wind picks up to a moderate breeze, so it’s messy.
Sunday the 20th is a fresh breeze at 19 mph from the north with only 0.7 ft. Forget it. Monday the 22nd through Friday the 25th is the same sad tune: light cross-off winds, and swell barely registering. The water temperature on that first Monday is 84°F, which is about average for the time of year, just a touch warmer.
Now, here’s where it gets interesting, but only for the brave. On the 26th of September (Saturday morning) and 27th (Sunday), we finally see some serious size. Corners gets a 12 ft swell from the SE on Saturday with a period of 11 seconds (that’s a solid groundswell) and combined wave energy roaring at 2718 – that’s very strong. This is expert territory only. The wind is a moderate cross-off from the NNE at 12 mph, which isn’t ideal but it’s manageable. Sunday holds 12 ft from the SSE, period still 11 seconds, energy 2686, but the wind picks up to a fresh 19 mph cross-off from the NNE. This is big, powerful, heavy reef surf. The long period (11 seconds) will bring good shape to the reef, but it’s only for those with serious experience.
Monday the 28th drops a bit to 8 ft from the SE with a shorter period of 8 seconds, energy 843 (moderate), and a fresh cross-off wind. Tuesday the 29th is down to 4 ft from the SW with a 10-second period, energy 256, fading fast.
So, the standout is clear: the 26th and 27th of September at Corners, if you’re an expert. That’s your window. Big SE groundswell, strong energy, and just enough wind to keep the surface from getting glassy clean. For the rest of us, it’s a write-off until then.
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.
