The Lowdown
Alright, mate, Rusty here. Let’s have a look at what’s cookin’ for our little patch of coastline.
Honestly, the next couple of weeks are a real test of patience. We’ve got a long, dry spell of small, messy, and mostly blown-out conditions before one monster of a day shows up way down the line. If you’re after a paddle, you’re going to be waiting.
First up, Corners is all we’ve got to work with. The water temp is sitting right on 84°, which is bang on average for this time of year – no surprises there.
The first real chance of anything surfable doesn’t even show up until Thursday the 20th of August. The morning brings a jump in size to 8ft from the SE, but it’s a cross-off wind from the SSE and the combined energy is moderate (1022). The forecast is marginal, and the tide could be a factor. It’s a bit of a gamble. The afternoon holds similar size at 7ft from the SE, with a period of 10 seconds, but the wind swings cross and the energy stays moderate (979). The surface gets a cross-chop, so it’s not going to be clean.
Then Friday the 21st of August sees the swell pump up to 10ft from the SSE, but the wind is a nasty cross-on from the S and SW. The energy is strong (1097-1202), but the waves will be a choppy, blown-out mess. Honestly, with that much wind and solid swell, it’s looking more interesting for the kite surfers than for a paddle surfer.
Saturday the 22nd and Sunday the 23rd are more of the same: 8ft dropping to 5ft, all with cross-on winds from the SSW and SW. The energy drops from 842 down to 288, but the quality is poor.
The whole of the following week, from Monday the 24th of August through to Sunday the 30th of August, is a total washout. Mostly tiny, onshore, or non-existent waves. The combined energy barely gets into double digits, with days of zero swell. It’s a proper blank run.
Now, here’s the standout, and it’s a long way off. On Tuesday the 1st of September, the forecast is for a *massive* pulse of swell. We’re talking 33ft from the SE early, dropping to 30ft from the SSE later, with a very long period of 14 seconds – that’s proper groundswell. The combined energy is off the charts at 37801. The wind is a fresh to strong offshore from the ENE, promising clean, glassy conditions. This is a massive, powerful swell. At 33ft, this is strictly for experts only. The period is so long that at a reef break like Corners, it should wrap in beautifully, but the power will be immense. It’s a real big-wave day, and the forecast is still a week and a half away, so it’s a promising but less certain one. Get your big wave gun ready.
So, the one and only true standout is that Tuesday the 1st of September. Everything else in the next 16 days is a write-off.
Stay patient, wait for that big one.
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.
