The Lowdown
Alright folks, it’s Rusty here. Let’s be real from the start – this is a tough one. We’re looking at a 16-day window for Corners, and for the first week and a half, it’s basically a no-go. There’s a massive gap from the start through to the 8th of August with nothing rideable. The water is a touch warmer than normal for this time of year, sitting at 86°F.
We’re stuck with tiny, weak swell and poor conditions right through the first week. Up to the 7th, it’s a wasteland of nothing, with some days showing zero swell at all. Then, on the 8th of August, things go completely nuts. The combined swell energy is absolutely enormous at 53356, and we’re looking at a 34ft swell from the south. That’s a hurricane-force monster. The wind is cross-off, but the swell is just too big, even for this exposed reef. It’s a spectacle, not a surf session.
The 9th of August drops to a 20ft south swell, still powerful with moderate wave energy (11491), but the wind swings cross-shore and it gets lumpy. It’s a marginal call at best. The 10th and 11th are still messy with strong onshore winds and dropping swell, from 8ft down to 5ft, but the wind makes it a blown-out mess.
Now, the real standout, and the only time I’d get excited, is on the 12th of August (Wednesday) . The morning session is the pick of the whole period. We’ve got a 4ft groundswell from the southwest, with a long 12-second period. The wind is glassy, coming from the SSE at 3 mph. It’s clean, it’s glassy, and the combined energy is a solid 803 (moderate). This is a proper reef-break wave with good shape. For an advanced spot, this is quality. The 13th of August (Thursday morning) is also a good call, with a 4ft SW swell, a 12-second period, and a light cross-off breeze from the NNE. That’s clean too, with moderate energy at 736. The 14th of August offers a smaller 4ft SW swell, but the period drops to 9 seconds, and the energy is weaker at 364.
So, the long and short of it: the first week is a write-off. The 8th is a dangerous, massive swell. The 12th and 13th are your best bets. Get on the 12th morning if you can – it’s the cleanest, most surfable wave in the whole forecast.
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.
