The Lowdown
G’day, it’s Rusty here. Look, I’ll level with ya – the next couple of weeks at Corners is a real mixed bag. We’ve got a run of ordinary to poor conditions for days on end, and it’s not until the end of August and into early September that things start looking interesting. There’s a big lump of swell building late in the piece, but it comes with a cross-shore wind that’ll keep it from being perfect. Let’s break it down.
We kick off Wednesday the 19th of August – honestly, don’t even bother. Tiny 1ft SW swell, period just 8 seconds, cross-off wind, and a risk of thunderstorms. The combined energy is a measly 24 (weak). The water temp here is 84°, which is about average for this time of year, no drama there. Thursday the 20th picks up a bit to 3ft to 4ft S swell, but still with a cross-off wind and more storm risk. Friday the 21st stays similar, around 3ft SW/SSW, but wind strengthens to a strong breeze from SE/ESE, making it ugly. Saturday the 22nd sees a jump – 10ft to 13ft SSE swell, but that’s paired with a strong cross-off breeze (28 mph) and thunderstorm risk. The combined energy hits 1628 (moderate to strong) but it’s blown out. Sunday the 23rd holds 10ft to 12ft SSE swell, period stretching to 11 seconds on the arvo, but still cross-off wind. The energy is 2975 (strong), but the surf quality is poor – just a marginal tick from the forecast. Monday the 24th drops back to 10ft then 6ft SSE, still messy. Honestly, all this wind and stormy vibe makes it look more like a kite session than a paddle.
There’s a bit of relief on Tuesday the 25th of August. Morning delivers 4ft S swell with offshore E wind at 16 mph, and the combined energy is 325 (moderate). The score is a 2 – “expect good surf conditions.” Still not epic, but cleaner. The arvo drops to 2ft SSW with a 10-second period – surfable but ordinary. Wednesday the 26th turns ugly again with fresh cross-shore wind from NNW and swell barely 3ft. That pattern of small, messy surf continues right through to the end of the month and into September 1st, with waves rarely over 3ft, mostly poor conditions, and combined energy often well below 100 (weak). A dry spell of several days, no lie.
But hold onto your board – we’ve got a standout on the horizon. Wednesday the 2nd of September is the one to circle. The swell jumps hard: 15ft to 16ft SSE, with a very long period of 14 seconds – proper groundswell. Combined energy is massive: 7536 to 9018 (very strong). Now, because it’s a long-period groundswell from SSE, and Corners is a reef break exposed to SW/SSE swell, it should wrap in nicely. The wind is cross-shore from NNW at 12-16 mph, so it won’t be glassy, but it’s not onshore either. This is expert territory – 16ft is only for the very experienced. The forecast gives it a 6-7 out of 10, which is the best we see in the whole window. Thursday the 3rd holds similar, 15ft to 16ft SSE, still with long 14-second period, energy over 6800 (very strong), but more clouds and cross-shore wind.
So the best on offer is Wednesday the 2nd of September into Thursday. Big, long-period SSE groundswell at Corners, just over a week away, but that cross-shore wind is a caveat – it’ll keep the surface from being perfect. Still, if you’re a confident surfer and can handle heavy reef waves, that’s your window. The rest is a whole lot of waiting.
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.
