The Lowdown
Alright, let’s get into it. The next couple of days are pretty quiet, but there’s a big pulse of energy coming late in the week that’ll light things up for the experienced crew. Patience is the call.
Right now, Sunday and Monday are subdued at Corners (a reef break). Swell is hanging around 5ft dropping to 3ft from the SSW, with a period around 9-10 seconds. Winds are cross-off from the E and ESE, so it’s clean enough, but the energy is weak (605 down to 168). Honestly, it’s just not doing much. You’ll see some rideable waves, but it’s marginal.
Tuesday drops off further, with swell down to 2ft and poor conditions. Wednesday the 26th gets ugly – a gale swings in from the WNW and WSW, with winds hitting 43-53 mph. That means 12ft to 13ft of blown-out, messy stuff. Don’t bother.
Now, hold on for Thursday the 27th. This is where it gets real. A serious SSW groundswell builds, reaching 16ft in the morning and 18ft in the afternoon, period stretching to 12 seconds. That’s a very long-period groundswell with massive energy (6303 to 7563). Winds are cross-off from the SSE and SE, keeping it clean. This is heavy, expert-only territory. The water temp is about average for this time of year, no major anomaly to note.
Friday the 28th is the standout. Swell settles to a still-chunky 13ft from the S with a 12-second period (energy 7073). Winds are a gentle breeze from the SE, cross-off, and the sky is clear. This is exceptional surf for experts – powerful, clean, and well-shaped. The optimum swell direction for Corners is SW, and this S swell will wrap in nicely. Crowds are often a factor here, so expect company if you’re going.
Saturday the 29th sees the swell back off to 7ft from the SSW, period 10 seconds, still clean with light winds. Good for experienced surfers, but the real magic was Friday.
After that, the surf fades. Sunday the 30th through early September sees dropping waves (4ft down to 2ft) and variable winds. There’s a brief uptick on Wednesday the 2nd of September with a 6ft SSE swell, but the wind is up and conditions are only marginal.
A much smaller pulse arrives on Saturday the 5th of September with 8ft from the SSW, but it’s onshore and messy from the W winds. Not worth your time.
So the clear winner here is Friday the 28th of August at Corners. Big, clean S swell (13ft), long 12-second period, gentle cross-off breeze. A proper for-experts-only session with excellent energy. Thursday the 27th is also pumping but comes with thunderstorm risk. Get it while it’s good.

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.
