The Lowdown
Alright, let’s get into it. Corners is a reef setup that handles a south-west swell best and it takes a bit of an easterly breeze to be clean. Water temp is sitting around 84°, which is pretty much spot on average for this time of year, so nothing weird there.
Right now, Saturday morning, we’ve got a small 2ft south-west swell rolling in at 8 seconds. That’s a short-period windswell, not much punch, but with the wind glassy out of the east, the surface is looking clean. The combined swell energy is weak at 129, so don’t expect much push. It’s surfable but pretty ordinary.
Saturday afternoon stays small, same 2ft, with a cross-off breeze keeping it clean, but still nothing to get excited about.
Sunday through to Thursday morning is a write-off. The swell stays tiny, mostly 1ft to 2ft, and the wind cranks up. Sunday and Monday have a moderate breeze cross-off, but the energy drops right off – weak as. Tuesday and Wednesday are just poor with stronger winds and bugger-all swell. Thursday afternoon shows a slight bump: 2ft south swell with a period bumping to 10 seconds, and a fresh offshore wind out of the east-northeast. Energy climbs to 103, but it’s still marginal. The wind is strong enough to make paddling a mission.
Then Friday the 21st of August sees a real change. A south swell pushes up to 6ft at 10 seconds – that’s a moderate groundswell with a bit of period – and the energy jumps to 582, moderate/strong. Morning has a fresh offshore breeze, so it’s going to be clean. That’s the standout of the whole period. It’s small enough for intermediates but has enough body for a fun session. However, by afternoon the wind swings northeast and hits 31 mph, a near gale, and that’s just too strong to paddle into.
Saturday the 22nd carries similar size, 6-6ft south-southwest swell, but again the wind is howling out of the northeast at 28 mph, strong offshore but borderline impossible to get out back. The energy is huge – 603-856 – but unless you’re a machine, it’s more of a windsurf or kite day.
Sunday the 23rd the swell drops to 4-6ft, but the wind shifts east-southeast and cranks up again, and it’s cross-off. Surf’s there but messy with the breeze.
From Monday the 24th right through to the end of the month, it’s back to poor. Swell stays small, mostly 2-4ft, and the wind is onshore or cross-shore, making everything lumpy or choppy. The 27th and 28th of August show a little window: 3ft south swell at 10 seconds, moderate offshore wind, and energy around 148-153. The surf is ordinary but at least clean. It’s a last-ditch option if you’re desperate.
Bottom line: the only real window is Friday morning the 21st of August. That’s your best bet. The rest is either flat, blown out, or too windy to enjoy. Corners needs a calm day to shine, and this forecast doesn’t give us many.

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.
