The Lowdown
Alright, Rusty here, changing units but keeping the story the same.
It’s a bit of a rough stretch ahead on the whole. We’ve got a lot of small, messy days, and some real flat spells to get through before we see any real juice.
At Corners, a reef break, the water is about 84°F, which is pretty usual for the time of year. Things start off on Tuesday the 11th with a 5ft south swell and a 10-second period. The combined energy reads a moderate 471, but the wind is a light cross-shore from the SSE, so the call is just marginal. It’s worth a look if you’re local, but not a trip-maker.
Wednesday the 12th and Thursday the 13th are a write-off for the most part. The swell sits around 4ft to 3ft from the south, but the wind is onshore or cross-onshore most of the time. Thursday morning is the only bright spot: clean conditions with a light NNE cross-offshore breeze and a 3ft south swell. The energy is weak at 193. Surfable, but average.
Then comes the real trouble. From Friday the 14th all the way to Sunday the 23rd, it’s mostly poor. The swells are tiny, the period is short, and the wind is often onshore or howling in from the wrong direction. There are some clean-looking windows in the mornings, but the swell is just too small to do anything with. The combined energy is weak, often under 200, and hitting lows in the 30s and 40s. It’s a real dry spell. A stretch like this is more normal for the area when the swell drops out.
We get a tease on Wednesday the 19th with a strong offshore wind from the ENE, but it’s on a 1ft to 2ft swell. That’s kite-surfing territory, not for a surfer.
The real standout finally arrives on Friday the 21st of August. The swell kicks up to 4ft from the SSE, the period is 8 seconds, and the combined energy pushes back up to 218. The wind is a clean, moderate cross-offshore breeze from the ESE. That’s the day to get in the water. The swell direction is right in that sweet spot for Corners.
After that, it’s back down. Saturday the 22nd is small again. Sunday the 23rd and Monday the 24th have a small, clean, long-period swell (10-11 seconds) with offshore winds, but the energy is only in the 100-140 range. It looks clean, but it’s not packing much of a punch. The rest of the month fades out into small, windy, and poor conditions.
So, mark your calendar for Friday, the 21st of August at Corners. That’s the one to be on. The rest is a lot of waiting and watching.
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.
