The Lowdown
Alright, Rusty here, let’s talk about what’s going on at Corners. The next couple of weeks are a real mixed bag, so let’s wade through it.
Right now, of this Tuesday the 25th, there's barely a ripple. That 2 ft SW swell from the morning window is weak, and the wind is a stiff 19 mph from the north, putting it cross-off. The combined energy is a measly 39, so don’t get your hopes up. It stays flat and messy through the rest of the week, with Wednesday the 26th actually seeing a jump to 8 ft WSW swell, but the wind is a screaming 31 mph onshore. That’s a big no-go, with combined energy hitting 728, but it's blown out and dangerous – more of a kiteboarding show than surf.
The rough stuff continues right through to the end of August and into the first few days of September. There’s a window on Sunday morning the 30th where we get a 4 ft SSW swell with clean offshore ENE winds at 16 mph. The combined energy is low at 213, so it's small, but if you're desperate and the shape is friendly, you might get a few. Crowds are likely at Corners, so keep that in mind.
Now, the real standout kicks off on Saturday the 5th of September. It’s over a week out, so keep an eye on it, but the forecast looks promising. We’ve got a solid 6 ft swell from the SSW in the morning, with the combined energy at 920 – that’s moderate, punchy energy. The wind is a beautiful dead calm, variable to light north, making for super clean conditions. Sunday the 6th of September looks even better. The swell drops slightly to 4 ft from the SW, but the period lengthens to a very long 14 seconds – that’s proper groundswell. The combined energy is strong at 1062, and with light offshore breezes from the east at just 6 mph, the face will be clean and lined up. This is your best bet, but remember, a long period like that can make it break a bit straight out the back at a reef spot like Corners. For experienced surfers, this is excellent.
After that, the energy winds down. By Monday the 7th and Tuesday the 8th, it’s back to small, clean but small, with winds staying offshore. It’s a fun end to the run, not a blockbuster.
So, to sum it up: we have a nasty, windy, blown-out first week and a half. The clear winner is the morning of Saturday the 5th and especially Sunday the 6th. With light offshore winds, a strong, long-period groundswell, and the water temp around a typical 84°, it's going to be clean and powerful. If you only pick one session, make it Sunday the 6th.

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.
