The Lowdown
Alright, Rusty here. Let's talk surf for the next couple of weeks.
We've got a wild few days ahead. The surf is coming in, but it's going to be a rough and windy ride before we see any real gems. There's a big gap of several days early on where, frankly, the surf is more of a kitesurfer's dream than a paddle surfer's.
The only break in the mix is Corners. It's an exposed reef break and it's going to get hammered by some serious swell energy, but the wind is a problem. From Thursday the 20th right through to Monday the 24th, we're looking at strong to gale-force cross-off shore winds with thunderstorms likely. The swell gets big—like 13ft on Saturday morning from the SSE with moderate energy (2799)—but it's going to be a messy, blown-out choptastic mess. Those 12ft to 13ft swells are solidly in the expert-only zone if you were even considering it, but with howling wind, this is not a paddle surf setup. You'd be better off on a kite.
Things start to clean up a little on Tuesday the 25th morning. We finally get some offshore wind—light from the East at 12 mph—and a smaller 4ft S swell with a 9-second period. The energy is low (262), but it's clean. The water is a warm 84°, which is just about average for this time of year. By Wednesday the 26th, we get a similar story: 4ft from the SSW with a 10-second period, light breeze, and clean conditions. It's nothing epic, but it's the pick of the bunch for the first week. The last real standout is Thursday the 27th morning: clear skies, a light N wind at 12 mph, and a 4ft S swell with a 9-second period. The energy is still modest (300), but it's surfable and clean.
After that, it trails off. From the 28th through to the 30th, the swell fades to under 3ft, and by the 31st it's looking poor and windy again. The first few days of September are just a write-off with gale-force cross-shore winds and thunderstorm risks. There's a little bump of swell on the 2nd and 3rd—3ft to 4ft from the SW—but with strong winds, it's not worth the effort.
So, if you're looking for the best of it, your window is Tuesday the 25th morning through Thursday the 27th morning at Corners. Don't expect much, and keep your expectations low for the rest of the run.
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.
