The Lowdown
Right, mates, Rusty here. Let’s have a look at what’s cookin’ for us over the next couple of weeks.
Straight up, it’s a tough start. We’re looking at a long, flat spell with nothing but tiny, weak dribble for the first week. The water’s a warm 86°, which is about 2° warmer than usual for this time of year – feels like bathwater, but that’s about the only positive.
We’re talking about Corners (reef), a fairly consistent advanced spot that usually needs a decent SW swell. But from today, Thursday the 30th of July, all the way through to Saturday the 8th of August, it’s a ghost town. The swell is either non-existent or microscopic – 1ft to 2ft at best – with periods under 10 seconds. The combined energy is laughable, barely hitting 37. It’s glassy a few times, which is a tease, but you can’t do anything with it. Then from the 3rd of August, the wind picks up, and we get a few days of clean, cross-off breezes, but with zero swell, it’s just a flat, clean lake. There’s a solid 8-day gap with no real surf on offer.
Then, hold onto your board. The 7th of August, Friday, the forecast goes absolutely mental. A massive 25ft to 26ft W/SW groundswell is predicted to slam in, with a very long period of 12 seconds and combined energy readings of 15957 and 23190 – that’s very strong energy. But the wind is howling at 75 to 80 mph, hurricane-force, cross-onshore, with heavy rain and thunderstorms. That’s not surf, that’s survival. The computer says it’s too big for this break, and I’d agree – that’s a solid no-go for anyone but the most insane big-wave chargers, and even then, the wind is a deal-breaker. This is way over 8ft, strictly for experts only, and with that wind, it’s dangerous.
The weekend of the 8th and 9th of August sees the swell dropping, but it’s still big, 12ft to 13ft, and the wind is still a messy, lumpy cross-shore gale. Not good.
The best chance of something rideable shows up on Monday the 10th of August. The swell drops to a much more manageable 5ft to 6ft from the S/SSW, with a 11 to 12 second period. The wind eases to a moderate breeze, cross-off, and it’s clean. The combined energy is moderate, around 1124 to 1210. It’s still a bit of a gamble with the risk of thunderstorms, but that morning looks like the pick of the whole two weeks. The swell is a bit big for beginners, but for intermediate and up, it’s your best shot.
From Tuesday the 11th onward, it fades again. We get clean, offshore winds on the 12th and 13th, but the swell drops back to 2ft from the S with a short 10-second period and weak energy. It’s just ordinary, small, and weak.
Overall, it’s a flat start, a dangerous spike, and then a small window of clean, fun-sized swell around the 10th of August. That Monday is your best bet.
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.
