The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s coming up for the next couple of weeks.
Honestly, it’s a bit of a rough start. For the first few days, we’ve got a serious pulse of energy from the south and southwest, but the wind is absolutely howling. You’re looking at a solid 18ft SSW swell with a 30 km/h gale from the south whipping it into a mess. That’s big, but it’s going to be a blown-out, dangerous beast. The combined swell energy is a massive 8070, so there’s plenty of power, but it’s all for the wrong reasons. Unless you’re a seasoned charger looking for a fight, stay on the beach for Saturday. The water temperature is 86°F, which is a touch warmer than normal for this time of year, so at least you won’t be cold while you’re watching.
Sunday and Monday are more of the same story: big, messy cross-chop from the SSE wind and loads of energy (4272 and 2116 respectively). The swell drops a bit, but the quality is junk. These are not days for a good time in the water.
Things start to look a little more interesting by Wednesday morning, the 12th of August. The wind finally drops, swinging to a light SE breeze, and by the afternoon we get a brief window of glassy conditions. The swell is down to 5ft from the SSW (9 second period), and the combined energy is a more manageable 353. It’s not big, but it’ll be clean. The problem is that Corners (your local reef break in the sub-region) is a fairly consistent spot that needs a solid SW swell, and this is on the smaller side. It’s worth a look if you’re desperate for a trim.
Thursday the 13th, a light NNE cross-offshore wind keeps the surface clean, but the swell drops further to 3ft from the SW. The energy is down to 273, so it’s a small, weak wave. It’s surfable but ordinary. This pattern of small, clean, but weak waves continues through to the end of the week and into the next weekend.
The real standout in this whole 16-day window is actually a pretty mellow one. If you’re after a session that’s not a battle, look at Wednesday afternoon, the 12th of August. The conditions will be glassy, the 5ft SSW swell (9s period) will be the biggest clean wave we see, and the crowds are a factor here – this spot is *often* busy, so you’ll have company. But for a clean, easy paddle, that’s your best bet.
Beyond that, from the 14th of August onward, the surf turns into a real struggle. The swell drops to below 3ft, with combined energy falling into the double digits (down to 35 on the 21st). The wind is a mix of cross-off and onshore, but the waves are just too small and weak to get excited about. There’s a solid 8-day gap of poor to marginal surf from the 15th to the 22nd. The second week offers nothing substantial. The 22nd of August sees a bit of a bump from the SSE with 4ft swell and clean offshore winds, but the period is a short 7 seconds, so it won’t have any punch.
To wrap it up: the first week has a massive, windy mess, one small but clean window on Wednesday the 12th, and then it’s flat and forgettable. The wait for the next proper swell might feel long.
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.
