The Lowdown
Right, let’s have a look at what’s on the cards for Corners. Straight up, the next week or so is pretty grim – small, weak, and ordinary. There’s a tiny window of something better at the very end, but it’s a long way off.
We're starting off with Corners. The water temp is about 84°, which is bang on average for this time of year. For Thursday morning the 13th, there might be a glassy moment with a tiny 3-ft S swell, but the energy is weak at 178 and it’s short period at 8 seconds. It’s surfable, but just barely. Thursday afternoon is a write-off with poor conditions.
Friday the 14th morning is glassy again with a similar 3-ft SSW swell, but still weak and ordinary. That trend holds through Saturday the 15th – glassy mornings, tiny swell around 2-ft, weak energy (126 and 105). Clean, but there’s hardly any push.
Sunday the 16th morning is a little better with a clean 3-ft SSW swell and a light cross-off breeze, but the energy is only 124. The afternoons all week are pretty poor or just ordinary.
There’s a bit of a pulse that shows up around Thursday the 20th afternoon, with a sudden jump to 8-ft from the SE, and the combined energy hits 952 – that’s strong. But the wind is a moderate cross-off from the ESE, and the period is still short at 9 seconds. This swell is pushing up into the 8-ft to 6-ft range through Friday the 21st, with energy in the 900s and 454. This is getting into expert territory, and it’s a fairly exposed reef break, so it’ll be powerful but messy with that cross-off wind.
The standout window, if you can wait, is on Saturday the 22nd morning. The swell drops to a more manageable 4-ft from the S, period still 9 seconds, but the wind is light from the E (cross-off) and the energy is a moderate 270. Conditions are clean. This is the best on offer – it’s not a classic, but it’s the most surfable window after a long dry spell. It’s still only 4-ft, so more of a fun-sized day for the experienced crew.
After that, it tanks again. From Sunday the 23rd onward, it’s mostly poor with building wind, and by Monday the 24th a strong breeze and then a near gale from the NNW just wraps it up. The last few days of the month show tiny swell and bigger wind. Friday the 28th morning might offer a tiny 2-ft S swell with light wind, but again, it’s small and ordinary.
So, overall? A pretty bleak run. The only real shout is Saturday morning the 22nd, but even then, keep expectations low. It’s been quiet, and it’s going to stay that way for a while.

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.
