The Lowdown
Alright, this is Rusty.
Well, to be honest, looking at the next two weeks, it’s a pretty grim picture for Corners. We’re in for a long stretch of nothing before things get interesting, and then it gets dangerous. Let’s break it down.
We’re starting off with a real flat spell. From Friday the 31st of July, right through to Wednesday the 5th of August, the swell is tiny – barely 1 foot from the SSE, with periods under 10 seconds. The wind is a mess of cross and cross-off stuff, so it’s not even clean. The wave energy is weak, with readings like 11 and 23, so honestly, don’t bother. You’ll be scratching around on a longboard for nothing. It stays like this for a solid week, with Thursday the 6th being a total washout with no swell at all and howling winds.
Then, things flip completely. The standout period, and I mean the only one worth talking about, is the morning of Friday the 7th of August. That’s a big, big swell. We’re talking 29 to 33 foot waves from the WNW with a period of 13 seconds. The combined energy is a massive 26,328, which is extreme. But here’s the problem: this is a reef break, and that size is only for absolute experts. Even then, the wind is a storm-force cross-shore, so it’s going to be a total mess. The guidance says it’s too big for this break, and I agree. The Saturday and Sunday after that are just as huge, with hurricane-force winds and dangerous conditions. This isn’t a surf session; it’s a survival situation. The water temp is a warm 86°F, which is a touch warmer than normal for the time of year.
After that chaos, the swell drops but the quality doesn’t improve. From Monday the 10th of August onwards, we’re back to small, weak swells. The wind stays strong and cross-shore, so nothing cleans up. The energy levels drop back to moderate, like 2,012 and then 713. The best you’ll see is a marginal 3 feet from the S on the morning of the 12th of August with a clean cross-offshore wind, but it’s not going to be anything special.
Look, this is a tough outlook. The only real surge is a dangerous one, and the rest is flat or poor. The pattern is clear: save your energy for mid-August and hope the forecasts change for the better.
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.
