The Lowdown
G’day, this is Rusty. Let’s talk about what’s on the table at Kandui Left. This is a reef break, fully exposed to SW swells, and the water’s sitting at about 85°F, which is pretty normal for this time of year – nothing unusual there.
The start is a bit average. From Friday the 28th through Sunday the 30th, we’ve got some waist-to-chest high swell running, but the wind is cross-shore and chopping things up, and the tide looks off. Not really worth suiting up for. Monday the 31st is a bit better – 6ft to 7ft SSW swell with a light cross-shore breeze, but it’s still marginal.
The first real standout comes Tuesday the 1st of September. The morning delivers a 8ft SW groundswell with a 17-second period, and wave energy is pumping at 3263 (moderate to strong). The wind is a light cross-shore, so it’s clean. That’s a powerful, long-period swell – best for experienced surfers at this size. Crowds are always a given here, so expect plenty of company.
Thursday the 3rd morning is another runner – 5ft SW swell with a clean cross-off breeze. Clean and excellent for experienced surfers. Then in the second week, Saturday the 5th morning sees a waist-high swell with light cross-off winds again, and Sunday the 6th morning jumps to 6ft from the south with a 16-second period, clean.
The absolute best windows come from Tuesday the 8th through Thursday the 10th. Tuesday afternoon the 8th goes glassy on a tiny 2ft SW swell – perfect conditions. Wednesday the 9th morning is glassy too, with 4ft of SW groundswell with a very long 18-second period. Thursday the 10th offers 5ft to 6ft SW swell with clean cross-off winds. This three-day stretch is the pick of the whole outlook. Friday the 11th afternoon goes glassy again on a solid 7ft SSW swell, and Saturday the 12th morning holds 7ft clean as well – but that’s expert territory.
First few days are flat-ish and messy, but from Tuesday the 1st onwards, there’s plenty of quality. Those glassy mornings from the 8th to the 12th are where it’s at. Don’t miss Thursday the 10th.
Rusty.

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.
