The Lowdown
Alright, Rusty here, let’s have a look at what’s cookin’ over the next couple weeks.
To be straight with you, the first few days are a bit of a write-off. There’s some size on the charts, but the wind is just messy – cross and cross-off with a fresh breeze, plus the risk of thunderstorms. The swell is mostly short-period, lumpy chop. Not worth paddling out for. That run of poor conditions lasts from Friday the 21st right through the weekend.
We start to see a glimmer of hope on Saturday the 22nd. The wind cleans up to a cross-off, and the swell bumps up. The standout window is Saturday morning. Corners is seeing a solid 10ft S groundswell, and with that cross-off breeze, the surface will be clean. The energy is strong, sitting at 2251. This is a powerful, expert-only wave at that size – well over the 8ft mark, so leave the foam boards at home. The water temp is 84°, which is bang on average for this time of year.
Sunday the 23rd drops back a bit – 6ft SSW swell, still clean with a cross-off ESE wind, but it’s only marginal. Not a standout, but if you’re keen, it’s rideable. Monday the 24th is similar, around 5ft and clean, but nothing special.
Tuesday the 25th is small, dropping to 3ft, and the wind swings around to a gentle offshore from the NNE. It’s clean, but tiny. Then things get weird on Wednesday the 26th. The swell jumps back up to 10ft from the WNW, but the wind is onshore and cross-on, making it a lumpy mess. Thursday the 27th is the same story – 8ft to 10ft of W swell, but that onshore wind kills it. This is more of a kite-surfing setup than a paddle session.
From Friday the 28th onwards, it’s a slow, quiet fade. The swell drops under 3ft, the wind stays cross-off or offshore, but the energy is weak (under 100 in the energy reading). The period gets longer, up to 11 seconds by early September, which would usually be a good sign for a point or reef, but the size just isn’t there. The water stays warm but the surf is flat and ordinary right through to the end of the forecast.
So the only real standout is Saturday morning the 22nd at Corners. Big, clean, powerful. Don’t miss it if you’ve got the skills. After that, it’s a waiting game.
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.
