The Lowdown
Alright, grab a coffee and settle in, I’ve had a good look at the charts for Kandui Left. The next 16 days are a proper mixed bag – a slow, choppy start, but there’s a beautiful run of clean, glassy conditions waiting for us in the first week of August. You’ll want to be patient for the good stuff.
The first few days, from the 26th of July through to the 29th, are pretty average. We’ve got a consistent 3ft to 5ft swell, but it’s coming from the SSE with a short, weak 10-second period and a cross-onshore wind that’s keeping things choppy and messy. The wave energy is moderate, sitting around the 500-600 mark, but it’s just not clean enough to get excited about. The water temp is a warm 86°, which is about average for this time of year.
Then, on the morning of the 30th of July, we see a real shift. The swell direction swings to the SSW, the period jumps to a very long 19 seconds, and the wind turns cross-offshore. The wave energy is strong (1251). This is groundswell. It’s clean, but it’s a reef break, so that long period will create some proper, powerful lines. For experienced surfers only, this is the first real standout.
The next few days are a bit of a write-off with that cross-onshore wind, but then we hit the real gold. The morning of the 4th of August is where it’s at. The wind is glassy, out of the northwest, and the swell is a solid 6ft from the SSW with a 16-second period and strong wave energy (1517). It’s clean, it’s powerful, and it’s a dream for the intermediate to expert crew. The 6th of August is another absolute stunner, with a 7ft SSW swell, a 16-second period, and glassy conditions. The energy is very strong (2188). And the 7th of August – the morning is completely calm, with a 6ft, 15-second swell and wave energy over 1583. Glassy perfection.
If I had to pick one or two true standouts, it’s the morning of the 4th of August and the afternoon of the 6th of August. Both have that magic combination of a good-sized SSW groundswell and glassy, offshore winds. The 7th of August morning is also a cracker. Crowds are inevitable at Kandui Left, so get in early.
After that, the second week gets a bit messier. The 8th and 9th of August have bigger swell, up to 7ft, but the wind picks up, creating a cross-chop. The 10th of August sees the swell pumping up to 8ft from the south, but with a strong cross-onshore wind, it’s going to be choppy and messy – more of a kite-surfing setup than a paddle session.

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.
