The Lowdown
Alright, surfers, Rusty here. Let’s have a look at what’s cooking at Corners.
We’re in for a long stretch of pretty ordinary conditions before things get interesting. The first week or so is mostly a write-off, but don’t walk away just yet—there’s a big pulse of energy showing up later that could make it all worthwhile.
The next few days are a real struggle. Wednesday the 26th is a total no-go with a strong cross-onshore wind and a messy, blown-out 10ft swell from the WSW. The wave energy is huge at 1014 (moderate) but the quality is shocking. Thursday and Friday are still marginal, with cross-shore winds and a lumpy 7ft to 4ft swell. The water temp is about average for this time of year, so no surprises there.
We hit a bit of a calm patch from Saturday the 29th through to early next week. Swell drops right off to around 3ft, but the winds turn offshore or cross-offshore, so it’s clean. Must be said, the waves are tiny and the energy is weak (184 to 71). It’s not really surfable for a proper session.
Then, from Wednesday the 2nd of September, a massive groundswell arrives. We’re looking at an 18ft to 20ft swell from the NW, with a period of 10–11 seconds and combined energy readings of 6116 to 8476 (strong). That’s serious power. However, the wind is a strong cross-onshore, which makes it messy and dangerous. That’s only for the absolute experts, and even then, it’s a tough call.
The best window looks like Thursday the 3rd and Friday the 4th of September. The swell drops to a still-chunky 13ft to 8ft from the WNW, but the period stretches to 12 seconds, which is a long-period groundswell. The wind turns cross-offshore and offshore, so the surface will be clean. The wave energy is still very high (5071 to 1058), and this is where the quality will come through. This is the standout period—big, clean, and powerful. It’s really only for experienced surfers, though, as an 8ft to 13ft wave is serious.
After that, the swell fades through the weekend and into the next week, with smaller, cleaner waves dropping to 5ft on the 5th, then fading to practically nothing by the 6th and beyond. The wind stays offshore but gets strong, making it hard to paddle into the tiny waves.
So, to sum it up: the first week is a write-off. The real action is from Thursday the 3rd to Friday the 4th of September at Corners, with a big, clean groundswell for the experienced crew. After that, it’s back to flat.
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.
