The Lowdown
Alright, let’s break it down for Corner. The next couple of weeks are a real rollercoaster.
Right now, Tuesday morning is flat and forgettable – 3ft of southwest swell, 10-second period, weak energy, cross-off wind. Not worth suiting up. Tuesday afternoon drops even smaller to 1ft.
Wednesday morning shows a bit more life: 4ft from the SSW, 13-second period, moderate energy, but the wind’s cross-on, so it’s a bit chopped. The afternoon cleans up nicely with light cross-off breezes, 4ft SSW swell and a solid 13-second period. That’s a clean, fun session for an intermediate.
Thursday is the big one. Morning brings a solid 10ft of SW swell at 12 seconds – that’s heavy, expert-only territory with massive energy. Wind is cross-off and clean, so if you’ve got the guts, it’s on. Thursday afternoon stays big at 8ft from the SSW, 14-second period, and excellent conditions for experienced surfers. Energy is still very strong. This is the best on offer.
Friday and Saturday are duds – poor surf, cross-on winds, small weak swells. Saturday afternoon actually has another 10ft SSW swell, but with strong onshore winds (28 mph) making it a blown-out mess.
Sunday sees another pulse of big swell: 10ft from the S at 14 seconds, energy through the roof, but cross-off wind keeps it clean. Still, that’s big and heavy, only for the experienced. Monday morning is a hidden gem: 5ft from the S, 11-second period, glassy conditions with barely any wind. That’s a clean, fun session for intermediates. Crowds are sometimes an issue here.
After that, the second week is mostly poor. From Tuesday the 25th through to the end of the month, it’s small swell, cross-off or cross-on winds, and weak energy. A few marginal windows – like Saturday the 29th morning with 5ft S swell at 8 seconds, clean but short period – but nothing special. The gap of real quality runs from the 25th all the way to the 2nd of September, where we finally see a tiny 3ft SSW swell with light cross-off winds. Surfable, but ordinary.
For kite surfers, the big windy days like Saturday the 22nd with 28 mph cross-off winds and 10ft swell might be more interesting than paddling.
Water temp is about average for the time of year.

Information about the Corner Surf forecast
The above surf forecast table for Corner provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Corner can be found by selecting the local surf guide option on the grey menu. Our Corner 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 (Corner) 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 Corner 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.
