The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the cards for Corners over the next couple of weeks. It’s a mixed bag, so I’ll break it down for you.
The outlook starts off slow. From Friday the 28th of August right through to Tuesday the 1st of September, it’s pretty bleak. We’ve got tiny, weak swell and fresh to strong winds that keep it messy. The water temp is sitting around 84°F, which is pretty normal for this time of year, so no surprises there. Honestly, you’re better off saving your energy for the back half of the forecast.
We finally see a spike of energy rolling in on Wednesday the 2nd of September. The morning brings a solid 10ft swell from the SSW, but it’s short-period at 8 seconds and the wind is cross-shore. The combined energy is strong at 1055, and this is a big, chunky wave. For a reef setup like Corners, that size is only for the experienced crew. The afternoon drops to 6ft but it’s still a bit wonky with the wind.
Now, the standout window is Sunday the 6th of September. The morning jump-starts with a powerful 10ft WNW groundswell at 8 seconds, and the combined wave energy is huge at 1237. Winds are cross-offshore, keeping things relatively clean for a reef break this size, but at over 8ft, this is expert territory only. The afternoon gets even bigger, with the swell jumping to 15ft from the WNW and the period lengthening to 10 seconds. Combined energy rockets to 3681. That’s a serious amount of water moving. The wind stays cross-off, so the surface should have some clean lines, but you’d better be on your game. This is the best on offer, but it’s a long-range call so keep an eye on it.
Monday the 7th of September still holds size, with 12ft from the W in the morning, but the wind shifts and the afternoon turns into a near-gale. Things then taper off quickly into smaller, cleaner conditions from the 8th onward, but the swell just doesn’t have the juice.
For a spot like Corners, which can be fairly consistent, this long run of nothing in the first week is a bit of a letdown, but those pulses in the second week make it worth watching. The highlight is without a doubt the Sunday the 6th session—big, powerful, and cleanish. Not for beginners, and crowds are often an issue here, so get there early if you’re keen. For the rest of us, it’s a waiting game.
Rusty out.

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.
