The Lowdown
Alright, folks, Rusty here. Let's talk about what's happening at Corners.
Right now, the next few days are a total bust. We've got a big, messy swell hitting on Saturday the 22nd – the combined energy is 1405 (moderate to strong), but that 3.0m S swell at 9 seconds is just wind-chopped and ugly. It's only just surfable, and that's being generous. Same story Sunday and Monday – the swell drops, but the wind stays cross-off and the conditions are average. The first week is a real letdown.
The real gem is waiting for us on Friday the 4th of September. That morning, Corners is looking at a solid 2.2m SE groundswell, with a period of 13 seconds – that's proper juice. The combined energy is a strong 1727, and the wind is blowing moderate offshore from the east. That means clean, lined-up waves on a reef that breaks fairly consistently. This is the one to circle. The swell direction is S, and the optimum is SW, so it's not a perfect match, but it's close enough for good shape. The water is about 29°C, which is pretty normal for this time of year.
That session on the 4th is for the experienced surfers only – 2.2m with a long period is too much for beginners. That 13-second period means the waves will have plenty of power and punch, with longer waits between sets, making it easier to get out. A reef break is the perfect spot for that kind of long period energy.
The 5th of September keeps the good vibes going. Saturday morning has a 1.7m SSE swell, still 12 seconds, with a fresh offshore breeze from the ENE. The combined energy is 918 (moderate), and it's rated as marginal, but that clean offshore wind makes it a great option for a smaller, more manageable wave. The afternoon gets bigger at 2.0m, but the wind goes cross-off, so the morning is the better bet.
Before that, there's a long dry spell from the 22nd of August all the way through the 3rd of September. Nothing but poor surf and marginal calls. A few tiny waves, like 0.8m on Tuesday the 25th, but nothing worth getting excited about.
So, the plan is simple: ignore this week. Save your energy for Friday the 4th of September early morning. That's the window. Clean, powerful reef waves.
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.
