The Lowdown
Alright, mate, Rusty here. Let’s break down the next couple of weeks. It’s a bit of a mixed bag, to be honest. We got some solid swell windows, but the wind is going to be the main factor in how good it actually gets. Don’t expect perfection every day, but there are a couple of sessions definitely worth circling on the calendar.
The first few days are pretty average. We kick off Tuesday morning with a clean-ish 6ft SSW groundswell, but that cross-shore wind has got it a little bumpy. The water’s a warm 85°, which is pretty much spot on for this time of year. The energy is moderate, sitting at 1455. Not terrible, but not great. The afternoon drops off a bit. Wednesday morning brings a glimmer of hope with a glassy 5ft SSW swell and the energy backing off to 826. It’s cleaner, but the size is a bit underwhelming. Thursday sees a jump in period to 19 seconds, which is a proper groundswell, and the energy climbs to 2166, but the wind is a bit messy, keeping things from being truly special.
Now, if you’re looking for the standout, keep your eye on the start of next week. From Monday the 31st, the swell starts to build and by Tuesday the 1st of September, we’re looking at a solid 8ft SSW swell with a 16-second period. The energy reading is a strong 3277, which is the biggest push of the whole period. The morning wind is light and cross, so it could be a bit lined up, but the size is getting serious. That’s one for the experienced crew.
The week after that, the size backs off a touch, but there’s a really nice window on Sunday the 6th of September. The morning has a clean, cross-offshore wind and a 4ft SSW swell. It’s not huge, but it’s clean and the energy is 815. It’s the kind of day where you can just get a few nice ones without a fight. Then on the 9th, we see the period jump back up to 19 seconds, but the swell is small and the energy is moderate. It’s a long-period groundswell, but it might be breaking a bit too straight on this reef for a proper wave.
So, the call is this: the big day is Tuesday the 1st of September, for the size and power. But for the cleanest, most user-friendly surf, that Sunday the 6th of September morning is your best bet. The rest of the time, you’re picking through the average stuff.
Rusty out.

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.
