The Lowdown
Alright, folks, Rusty here. Let’s cut through the noise and look at what’s actually on the table for the next couple of weeks. It’s a bit of a mixed bag, so let’s get into it.
The immediate future is pretty flat and blown out, with some stormy weather kicking things off. Wednesday the 19th and Thursday the 20th are basically a write-off – small, weak swell, maybe 1 to 3 feet, and the wind is messy. You’d be spending more time untangling your leash than surfing.
Friday the 21st isn't much better. The swell bumps up a touch to 4 feet but it’s still pretty junky. There’s a lot of cross-shore wind, and the energy is weak. Honestly, not worth the paddle out unless you’re desperate.
Now, hold onto your board, because Saturday the 22nd is where things get interesting. By the afternoon, the swell jumps to a solid 13 feet from the SSE with a 10-second period. That’s some serious juice. The wind eases off to a gentle cross-off breeze, which will clean it right up. This is the standout of the week for experienced surfers. Corners will be handling this size well. If you're not confident in big surf, this is not the day for you. This is a day for charging.
Sunday the 23rd is still big – 15 feet in the morning – but the wind is howling at 28 mph and up to 31 mph in the afternoon, which is going to rip the face off it. It's going to be a messy, blown-out mess. Monday the 24th is similar, still sizeable, but the wind strength is a problem, creating poor conditions.
The swell starts to back down into Tuesday the 25th, down to that 4 to 4 feet range, and we finally get some proper offshore winds. It's smaller, but cleaner. It’s a salvageable day for some fun smaller waves, but nothing to write home about.
Then we hit a real dead spell. The wind goes nuts with severe gales and big, stormy surf from the 26th through the 29th. The swell is all over the place, short period, and blown to bits – that’s a kite-surfing wind, not a surfing wind. There is a silver lining here, though.
Mark your calendars for Sunday the 30th of August. The forecast shows a drop in wind to a slight air, with a nice clean cross-off breeze. The swell is a clean 5 feet from the WNW with a 10-second period. It has the makings of some really fun, clean waves. This is your other standout. It’s about as good as it’s going to get in this window. After that, we fade back into the doldrums – small, weak, and mostly blown out as we roll into September.
So, to sum it up: Saturday the 22nd for the big-wave crew if you’re keen, and Sunday the 30th for the rest of us who want some clean, manageable surf. Everything else is a wait-and-see or a no-go.
The water temp is around 84°, which is about average for this time of year, so a spring suit will be fine.
Keep the faith, it tends to turn around.
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.
