The Lowdown
Alright, fellow wave hunters. Rusty here, and I’ve taken a long, hard look at what’s coming our way. It’s a tale of two extremes, so strap in.
First off, the next week or so is a total write-off. We’re looking at flat, weak conditions with barely a bump on the surface. The combined swell energy is struggling, mostly under 30 (30). It’s a frustrating stretch of tiny, poor surf, and honestly, there’s nothing to get excited about. You’d be better off tuning up your board or doing some reef walking.
But don’t lose hope, because the second week brings a monster. The real story is the morning of Friday, 7 August. The models are showing a massive, powerful swell slamming into Corners (reef). Swell heights are predicted to hit a staggering 23 ft from the WSW, with a very long period of 12 seconds. The combined energy reading is off the charts at 20163 (20163). This is serious, heavy, groundswell energy. This is not a day for the faint of heart. The wind and tide notes say it’s favorable, but at this size, it’s strictly for experts only. The long period will make it a proper, deep-water bomb, perfect for a reef like this, but it will be relentless.
The morning before, Thursday, 6 August, also sees a massive, dangerous swell, with 16 ft from the NW and a violent storm-force wind. That’s a big, dangerous mess, not surfable. The real standout for the truly skilled is that Friday morning.
After that peak, the swell drops but remains solid through the weekend. Sunday, 9 August morning offers a much more manageable 6 ft from the SSW, with a 12-second period and clean, cross-offshore winds. The energy is still strong at 1445 (1445). This is the best of the rest, offering excellent conditions for experienced surfers who want big, clean waves without the death-defying size of Friday.
The water is sitting at a warm 86°F, which is a touch warmer than normal for this time of year.
So, to sum it up: endure the flat spell, then mark your calendar for Friday, 7 August for the biggest, most serious swell of the window. If you’re legit, that’s your day. For everyone else, Sunday, 9 August morning is the clean, powerful option.
Stay safe out there.

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.
