The Lowdown
Alright, let’s talk in feet and miles per hour. Corners is looking at a rocky start, with a few windows of clean surf if you’re willing to wait.
Sunday the 23rd kicks off with 5ft swell from the SW at 10 seconds. The wind is a cross-off from the ESE at 12 mph, keeping things tidy. Water temp is 84°F, normal for the season. Combined energy is moderate at 415. Sunday afternoon sees the swell bump to 5ft from the SSW, still clean.
Monday the 24th drops to a weak 3ft from the SW with a short 8-second period. Energy plummets to 117. Tuesday the 25th is even smaller at 2ft and 2ft, with a strong north wind.
Wednesday the 26th gets hairy. Risk of thunderstorms and a severe gale from the WSW at 47 mph. Swell jumps to 15ft from the WSW at 9 seconds, with massive energy at 4872. It’s blown out and dangerous. Thursday the 27th keeps the energy with 13ft from the SSW at 12 seconds (4182 energy), but a strong cross-shore wind at 25 mph makes it lumpy. Thursday afternoon might clean up a bit with a cross-off wind, but it’s still 12ft – experts only.
Friday the 28th morning is your best bet. 8ft from the SSW at 11 seconds, energy 1587, with a clean cross-off wind from the ESE at 12 mph. Saturday the 29th morning is also good with 7ft, same period, and clean wind.
Sunday the 30th afternoon has a small 4ft from the SSW, but the wind turns offshore from the E at 12 mph, making for glassy conditions. Energy is low at 232.
From Tuesday September 1st through Saturday September 6th, the swell is tiny – 1ft to 3ft – with energy often under 100. Strong winds but no waves. Sunday September 7th is the same.
The standout is Friday morning August 28th: 8ft, clean, long period, and manageable for advanced surfers. Saturday morning August 29th is a close second.
Anything over 5ft is too big for beginners, and the 13ft+ days are for experts only.
Signing off, 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.
