The Lowdown
Alright, Rusty here. Let's have a look at what's on the table for the next couple of weeks.
Honestly, it's a grim stretch for Corners. The whole 16-day window is a bit of a write-off. We're looking at a long, dry spell with barely a ripple. The water's sitting at 81° which is a good bit colder than you'd expect for this time of year – about 3.4° off the mark, so you'll feel that nip.
The first recommendation doesn't come in until Sunday the 19th, and even then it's a struggle. The swell is a weak 2.3ft from the SW, with a short period of 8 seconds, and the combined energy is a paltry 84. It's only holding on because of the glassy conditions in the morning. That's your one saving grace – it'll be clean, but the waves themselves are ordinary. The afternoon on Sunday gets a bit of a cross-onshore breeze, so that window shuts fast.
After that, it's a long, bleak run. From Monday the 20th right through to the end of the month, the swell barely registers. The heights are tiny, the periods are short, and the combined energy is weak, often dropping into single-figure values. We're talking 1ft to 2ft of slop most days. There are a few mornings with glassy conditions, like Tuesday the 21st and Wednesday the 22nd, but the swell is so small it's not worth paddling for.
Just when you think it's over, we get a bit of a tease. On Saturday the 25th and Sunday the 26th, the direction swings to the SE with a longer period – 11 and 12 seconds – and the energy finally climbs into the triple digits (125 on Sunday morning). The wind is clean, offshore even. But the size is still minute, barely 1ft to 2ft. It's a promise of quality with no substance. Then the wind goes absolutely mental. On Monday the 27th, we're looking at a violent storm-force wind from the NNE, hitting 71 mph. That's not surfing, that's survival. The whole week after gets hammered by gale to near-gale force cross-onshore winds whipping up a messy, choppy, blown-out sea. The swell does bump up to 4.3ft on the 29th, but with a 6-second period and fresh cross-onshore winds, it's a complete mess. It's more of a kite-surfing setup than anything you'd want to paddle into.
Bottom line: there's nothing here to get excited about. The best you'll find is a tiny, clean wave on Sunday the 19th morning, but it's barely surfable. Otherwise, you're better off finding something else to do for two weeks.

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.
