The Lowdown
Alright folks, it’s Rusty here, and I’ve got a look at what’s coming up for Corners over the next couple of weeks. Gotta be straight with you – it’s a tough stretch. We’re looking at a long, dry spell of poor conditions before we finally see a glimmer of something worthwhile.
The overall pattern is pretty grim. For the first week, we’re dealing with a mix of strong winds, cross-shores, and tiny, weak swell. The water temperature is sitting at 83°, which is pretty much normal for this time of year, so at least you won’t need a thick wetsuit.
The first real chance of a surf pops up on Friday the 4th of September. The morning is still a bit messy with a light cross-onshore breeze and a small 4ft swell from the S, but the afternoon is the standout. The wind drops to glassy – just a light air from the SE – and the 4ft S swell has a clean 10-second period. The combined energy is moderate (332), and it’s the only time in the whole run where the conditions actually line up for a decent, clean paddle. This is the best on offer, but it’s a small window, so don’t sleep on it.
After that, it’s back to the grind. There’s a bit of a pulse on Monday the 7th of September, with a big 13ft SE swell rolling in, and the combined energy is massive (5370). But the wind is a fresh cross-offshore at 35 km/h, and the forecast warns of marginal conditions. That’s a lot of water moving around for a reef break, and with the wind on it, it’s going to be a wild, lumpy mess. That’s strictly for the experts only, if anyone is mad enough to try it.
The rest of the second week stays poor. A mix of strong cross-shore winds and lumpy chop keeps things ugly. We get a tiny blip on Friday the 11th of September, with a clean offshore wind and a knee-high 2ft swell from the SW, but the period is short (8 seconds) and the energy is weak. It’s surfable, but only just.
The final weekend, the 12th, is a write-off. The wind is howling near gale to severe gale force offshore, making it ridiculous to even think about paddling out.
So, to sum it up: the only real window of clean, surfable waves is the afternoon of Friday the 4th of September. Mark it on your calendar, but don’t expect much else. The rest of the 16 days is a long, frustrating gap.
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.
