The Lowdown
Alright, let’s get this forecast sorted. First up, the next week and a half is looking bleak. We’ve got a whole stretch of nothing but tiny, weak swell and poor conditions. From the 15th through the 25th, there’s just no energy in the water. We’re talking flat spells, onshore breezes kicking up chop, and storms threatening to spoil the fun. It’s a write-off for any real surfing.
Then, things start to change. We see a pulse of smaller, longer-period swell on the 26th, but it’s not clean. A bit cross-onshore and choppy. The real deal, the standout, is the 28th. We get a huge jump in size and quality. The overnight and morning of the 28th delivers. That’s the window you want.
Corners is the spot. It’s an exposed reef break, and it’s fairly consistent, but you need to know what you’re doing out there. This is advanced territory.
On the 28th morning, the swell is coming from the southeast at 13ft, with a solid 16-second period. That’s a serious groundswell. The total energy in the water is massive – we’re talking four digits here, 7411 to be precise. That’s powerful. The wind is light and cross-offshore out of the north, which should keep it pretty clean. This is an exceptional morning for expert surfers.
The afternoon gets a little bigger, pushing 15ft, but the tide and wind might get a bit more questionable. The period stays long at 16 seconds. The energy jumps up even more to 8630. Still, that’s a lot of water moving.
Then, the following morning on the 29th, the swell is even bigger, hitting 16ft. The period stays long at 15 seconds, and the energy is through the roof – 12345. But it’s also getting into dangerous territory. There’s a risk of thunderstorms, and the wind is picking up a bit. For most people, this is too big. This is proper expert-only, big-wave stuff.
So, the standout is clearly the 28th morning at Corners. It’s a groundswell, and it’s clean, powerful. Just know your limits. The water temperature is around 84°, which is about normal for this time of year, so you won’t need a thick wetsuit.
This is a long-range call, so things might shift, but if you’re an advanced surfer looking for a session, that’s the one to circle.

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.
