The Lowdown
G’day, this is Rusty. We’ve only got one spot on the radar for the next 16 days: Kandui Left. It’s a reef setup that loves swell from the southwest, and that’s exactly what’s on the cards. The water’s sitting at 85.3°, which is pretty much bang on average for this time of year, so no surprises there.
There’s no surf worth talking about until Thursday morning the 3rd of September, and even then it’s a bit average. Thursday morning sees 4.9ft of SW groundswell with a period of 14 seconds, but the wind’s a cross sea breeze at 9 mph, so expect a little chop. The combined energy is strong (1091). Thursday arvo’s a write-off: same height, but a cross-onshore at 6 mph makes it messy.
Friday the 4th is where we start seeing a glimmer. The morning has 4.3ft of SSW swell (13-second period) with a clean cross-offshore breeze at 9 mph – that’s the first decent window. Energy’s moderate (726). Friday arvo the wind turns cross-on, so the morning’s the go.
Saturday the 5th is a bit of a tease. The swell drops to 4.3ft in the morning and 3.6ft in the arvo, both with a very long 17-second period from the SSW. That long period means the wave shape should be nice and lined up, but the cross-shore wind (9 mph) keeps it from being glassy. Energy is strong (1112 morning, 1089 arvo). It’s surfable but not a standout.
Sunday the 6th gets blown out. 4.6ft swell in the morning with a moderate cross-shore at 16 mph – lumpy. Arvo sees the swell drop to 2.6ft but the wind howls at 19 mph from the SSE. Not worth paddling out. Energy is very strong (1579) but ugly.
Monday the 7th is poor. 4.3ft swell with a cross-shore at 16 mph in the morning, and the arvo turns worse with a moderate cross-onshore at 12 mph – choppy as hell. Energy stays strong (1122, 1130).
Tuesday the 8th sees the swell at 4.3ft in the morning with a very long 18-second period from the SSW. Wind is a gentle cross-shore at 9 mph – okay but not stellar. The arvo has 3.3ft with the same long period (18 seconds) and nearly glassy conditions (3 mph cross-shore). The energy jumps to very strong (2116 arvo). It’s a chance if you’re keen, but the tide might be a factor.
Now, Wednesday the 9th of September – that’s a proper highlight. Morning brings 4.9ft of SSW groundswell (15 seconds) with a clean cross-offshore breeze at 9 mph. Energy is strong (1477). The report calls it excellent for experienced surfers. This is one of the best on offer. The wind stays clean, so the reef should be working nicely.
Thursday the 10th is another standout. Morning: 5.2ft of SSW swell (16 seconds) with glassy conditions – wind is just 3 mph from the ESE, dead glass. Energy is very strong (1739). This is the best session of the whole run. Absolutely pristine conditions for that reef. Get on it early.
Friday the 11th also looks excellent in the morning: 5.6ft of SSW groundswell (16 seconds) with a cross-offshore breeze at 6 mph. Clean and punchy. Energy very strong (1705). The arvo gets a cross-onshore, so stick to the morning.
Saturday the 12th has 4.6ft of SW swell (14 seconds) in the morning with a clean cross-offshore at 12 mph, but the real gem is the afternoon:
Short Range ForecastModerate rain (total 18mm), heaviest on Thu morning. Warm (max 28°C on Thu morning, min 26°C on Fri night). Winds increasing (calm on Fri night, fresh winds from the SE by Sat night). | Days 4-6 Weather SummaryHeavy rain (total 25mm), heaviest during Tue morning.

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.
