The Lowdown
Alright, grab your board. Let’s talk about what’s coming up for Corners (reef).
Straight up, it’s a slow start. We’ve got a flat spell for the first few days. Tuesday the 21st through to Thursday the 24th is basically a write-off – tiny, weak swell with poor conditions. You’re looking at waves around 0.7ft to 2ft and the wind is either onshore or just messy. The combined energy is barely registering (48 down to 8), so don’t even bother paddling out. It’s a real quiet patch.
Friday the 25th starts to show a little life. The morning is still pretty weak, but the afternoon brings a bump up to 4ft from the SE with a period of 10 seconds. The energy jumps to 263 (moderate) and the wind is cross-offshore, keeping it clean. It’s still marginal, but you can see the pulse coming.
Now, hang on. Saturday the 26th builds. Morning sees 6ft, afternoon hits 7ft from the SE. Energy is climbing (589 to 784), and the wind stays cross-offshore. The period is still 10 seconds, so it’s a bit of a short-period swell, but it’s getting there. This is more for the experienced crew – 7ft is getting chunky for beginners.
And then… Monday the 27th. That’s the real standout. This is the one we’ve been waiting for. The morning brings a solid 12ft from the SSE with a 12-second period. That’s a proper groundswell, and the energy reading is 5609 – that’s strong, very strong. The wind is offshore from the E, so it’s going to be clean and lined up. This is exceptional for experts. The afternoon drops a bit to 10ft, but still excellent. If you’re an advanced surfer, this is your day. The swell direction is SW optimum, and we’re getting SSE, which is close enough to work well on this reef.
Tuesday the 28th is still pumping big, but the wind switches cross-onshore. The swell is 12ft from the S, but it’s going to be choppy. The energy is massive (3668 to 7088), but the quality drops. It’s big, but messy. Wednesday the 29th drops a bit to 8ft, still cross-onshore, and it’s fading. After that, it’s a steady decline. Thursday the 30th and Friday the 31st are back to poor, onshore junk. By the start of August, the wind is howling – 37 to 62 mph cross-shore. That’s not surf, that’s a washing machine. The swell is tiny and the conditions are blown out. Forget about it.
So, the call is simple: the first few days are a total bust. The best surf on offer is Monday the 27th. That’s the standout. Big, clean, offshore, powerful. It’s for experts only. Earlier on Saturday the 26th is a decent warm-up if you’re comfortable in the 7ft range. The rest of the run is either too small, too windy, or too messy.
The water temperature is about average for this time of year, nothing extreme.
Stay sharp, and don’t sleep on that Monday.
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.
