The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cooking for Corners.
Straight up, I’m not gonna sugarcoat it: the next week and a half is a write-off. From now through to the 19th of September, we’re staring at a long, flat gap with nothing but tiny, wind-chopped leftovers. The swell is barely a ripple, and the wind is cross-off or worse, making it feel like a waste of time. The combined energy sits at pitiful numbers like 26 and 8, confirming there’s just no grunt in the water. Don’t bother paddling out.
But hold on. The 20th of September is where things get interesting. This is the standout. Sunday morning, the southeast swell kicks in at 3 ft, with a nice 13-second period. The wind is light and offshore from the east, so the face will be clean. The combined energy jumps to 602 (moderate), which tells you there’s enough push to get you moving. Come Sunday afternoon, we’re looking at 6 ft from the southeast, period stretching to 14 seconds, and the energy is already at 1484 (strong). That’s the window for experienced surfers – the sets will have some punch.
Then Monday the 21st of September is the true highlight. Morning brings 8 ft from the southeast, 14 seconds, with offshore wind from the east-northeast keeping it glassy. The energy is pumping at 2201 (very strong). By the afternoon, it’s 8 ft, 15-second period, still offshore, and the energy is 2612. This is serious, big-wave territory – only for the experts. The swell is coming from the southeast, which matches the optimum direction for Corners (SW), so it’s going to line up proper on the reef.
But the crown jewel? Tuesday the 22nd of September. Tuesday morning, we’ve got 12 ft, 16-second period, clean cross-off wind, and the energy is a colossal 6863 (very strong). Tuesday afternoon is the monster: 15 ft, 16-second period, and the combined energy hits 10215 (exceptional). This is a once-in-a-while event. The swell is long-period groundswell, so expect big, well-shaped lines that will stand up on the reef. The wind is light, so it’ll be clean. But this is expert-only. If you’re not confident, watch from the rocks.
After that, the 23rd and 24th drop off again with very little on offer. The 24th afternoon has a 7 ft northwest swell, but it’s mixed with strong offshore winds (40 km/h) that will make it a battle to paddle into. I’d skip it.
For the water temp, it’s sitting at 84°F, which is bang on average for this time of year, so just board shorts and a rashie.
In summary: suffer through the flat spell, then the 20th through the 22nd of September is the real deal. The absolute best is Tuesday the 22nd afternoon – that’s the one you want to be on the reef for. It’s a long-range call, so keep an eye on it, but it’s looking like a proper session.
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.
