The Lowdown
Alright, let's talk waves.
The next week and a half is a bit of a mixed bag around here. We've got some fun energy showing up, but the wind is going to be the big player. It's all about picking your sessions.
The first few days, Tuesday and Wednesday, we're looking at small surf with a bit of a fresh offshore breeze, keeping things clean but without much push. The combined energy is weak, around 57 to 61 on Tuesday, building slightly into Wednesday. It's rideable on a longboard, but not exactly going to get the heart rate up. A little bit of a south swell mix is in there.
Thursday sees a bit more size, maybe 4ft, but the wind switches onshore and it gets messy. That's a day to stay on land. Friday's a bit of a wash-out, and even the bump in energy (452) won't save it.
Now, Saturday the 5th looks like the first real window. The wind drops out, going glassy in the morning with that swell still hovering around 3ft. It's not big, but it's clean and could be fun on the inside. Then by Saturday afternoon, that south swell kicks up to 5ft and with light offshore wind, things start to look more interesting. Combined energy jumps to 454.
The weekend into next week stays a bit inconsistent, with the wind filling in on Sunday and Monday. It's not terrible, but again, the quality is just okay. The swell is still there, around 3-4ft, but the cross-off winds aren't ideal.
Things get serious on Monday the 14th. That’s when the ocean starts to wake up. We're looking at a solid 6-7ft south swell with a 14-second period, and the wind is offshore from the ENE. Combined energy is a massive 1454. That’s the standout morning. Corners (Big Island) is a reef break that handles this kind of groundswell well, and it's going to be proper. This is the one to circle. The water temp is sitting at 83°, which is about average for this time of year.
After that, the swell just keeps on coming. By Tuesday the 15th, it’s pushing 10ft at 15-16 seconds, and Wednesday the 16th is looking huge, at a solid 15ft. But at that size, with the winds being cross-off, it’s going to be a serious, expert-only affair. This is definitely NOT for beginners—anything over 8ft is only for the experienced crew. That big, long-period groundswell might be a little too straight coming in at the beach, but at a reef like Corners, it could be something very, very special. Keep in mind, it’s a bit of a trek out in the forecast, so don't book your flights yet.
Before that, though, the period from the 9th to the 13th looks a bit messy. Winds are up and the swell is a bit inconsistent. But don’t worry, it looks like the ocean is just building for that epic run to finish up the 16-day window.
I'll be in the water on that Monday, that's for sure.

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.
