The Lowdown
Alright folks, Rusty here. Let’s get into what’s shaping up around Kandui Left. For the first several days, it’s a bit of a struggle with messy conditions, but the second half of the run has some real firepower locked in if you’re patient.
Right now, it’s a mixed bag. The water temp is sitting at 30°, about 1° warmer than the annual usual – not a big shift, just a touch toastier than average for this time of year. Friday the 28th kicks off with some inconsistent 7ft SSW groundswell coming in at a long 16 seconds, so there’s push, but the cross-shore wind has it looking choppy and average at best. That early energy is pretty high, but the quality just isn’t there. The weekend looks flat and messy, with dropping size and moderate cross-shore breezes – not worth getting wet for.
We see a gradual pickup heading into the new week. Monday the 31st has a solid 6ft to 7ft SW swell with a long period, but still, the winds are cross-shore, so it’s going to be lumpy. Tuesday September 1st shows the biggest size yet at 8ft SW with a period of 17 seconds. That’s a powerful, meaty groundswell, but still let down by the breeze.
The turning point looks to be the morning of Thursday, September 3rd. For the first time, we get a clean session with cross-offshore winds, 5ft SW swell at 15 seconds. The setup is finally lined up and the wave face should be groomed. That’s a decent window for the experienced crew.
Later on, things get really interesting. Thursday, September 10th dawns with glassy conditions – absolutely dead calm – and a solid 5ft SW groundswell with 16-second period. That’s the kind of morning you wait for. But the standout period is September 11th and 12th. Friday the 11th pulls in a serious 8ft SSW swell with 17-second period. The wind goes cross-offshore in the afternoon, cleaning it right up. That is big, powerful, long-period swell – definitely for experts only. Saturday the 12th is an absolute stunner: glassy conditions all morning and afternoon, with a steady 8ft SSW swell and 17-second period. It’s going to be a long-period groundswell, so it’ll unload with real punch. Expect well-shaped, heavy waves with long waits between sets, which makes paddling out a bit easier – but you better be on your game.
Overall, the first week is mostly a write-off. The real action hits from September 10th through 12th. Thursday the 10th and Saturday the 12th are the absolute pick of the run for clean, glassy, powerful surf.
Stay patient, check the tides, and get ready for some serious Kandui Left magic.

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