The Lowdown
Alright mate, Rusty here, and I’ve got a look at what’s coming up for Corners. Let’s just say it’s a mixed bag with a bit of a wait for the good stuff.
Right now, we’re kicking off with a flat spell. The first few days are pretty grim – Thursday the 19th and Friday the 20th are all about tiny, weak swell and stormy winds, nothing to get excited about. The water’s sitting at 84°F, which is bang on average for this time of year, so at least you won’t need a thick suit.
We’ve got a bit of a gap before anything really shows up. Saturday the 22nd is where things start to get interesting, but it’s not for the faint-hearted. A big pulse of swell rolls in, with combined energy hitting a massive 3168, and waves pushing 13ft. That’s serious, expert-only territory. The wind is cross-off, so it’ll be clean, but that size with a short period of 10 seconds means it’ll be a handful. Sunday the 23rd keeps the juice going with 12ft swell and energy at 2868, but again, that’s for the experienced crew only.
The standout, and the one I’d be circling on the calendar, is Sunday the 30th of August. Finally, the conditions line up. We’ve got a nice 4ft swell coming from the NW with a 10-second period, and a light, cross-off breeze from the NE. That’s the recipe for clean, lined-up waves at this reef. The water’s still warm, and the energy is a manageable 468. It’s consistent here, so you’ll get plenty of waves. Crowds can be an issue though, so get in early.
After that, it trails off again. The first week of September looks small and messy, with a few short-period bumps that won't do much. The 3rd of September shows another pulse of 8ft from the NW, but with a short period of 7-8 seconds and a fresh cross-off breeze, it’ll be a bit lumpy and best for the advanced crew.
So, bottom line: if you’re an expert, the big weekend of the 22nd-23rd is on, but for the rest of us, hold out for that beautiful Sunday the 30th. That’s your best bet.
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.
