The Lowdown
Alright, let's get real. It's looking like a slow grind for a while. For the next stretch, we're staring at small, weak surf. For days on end, we’ll have ankle-biters and barely enough energy to push you over the foam ball. This flat spell runs through the 19th. Don't even bother.
Come the 20th of August, it gets bigger but it turns to junk. We’ll see the swell jump to around 2.3m, but the wind will be blowing onshore and cross-shore, tearing the surface to pieces. The energy will be there, but it'll be a washing machine. Not a surf day. That rubbish holds on for a few days, slowly fading out.
Then, we get a little taste of clean. By the 23rd, the wind dies and we hit a glassy 0.7m. It’s tiny, but clean. The morning of the 24th will also be glassy, but still pretty small.
Now, the one to circle on the calendar: Monday, the 31st of August. That's the day. We’ve got clean, light offshore winds and a new, better quality groundswell pushing in at 1.1m. It’s the biggest, cleanest swell of the whole window. Corners, the reef, will be the spot. The period is a touch longer, so it should have a bit more push. It’s not going to be a massive day, but it’s our only real standout. That’s the session to chase.
The water’s at 29°, which is about normal. So, keep the powder dry and wait for that last day of August. That's the one.
Rusty out.

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.
