The Lowdown
Righto, grab a coffee and settle in, 'cause the surf story for this stretch is a bit of a mixed bag. We’re looking at Tandjung-Lefts, a solid advanced reef break that's fairly exposed to the swell. The water’s sitting at a pretty standard 80° for this time of year, so no drama there.
The first week is a bit of a write-off, to be honest. The wind is stubbornly coming from the east-southeast, putting a cross-onshore chop on everything. We’ve got a consistent SSW swell hanging around 5 to 6 ft, with a solid 14 to 16 second period – that’s proper groundswell energy. But the wind just kills it. You’ll be looking at choppy, bumpy conditions with poor surf quality from Monday the 14th all the way through the week. The combined energy is moderate to strong (values in the 1000-1400 range), but it’s just not clean enough to get excited about.
We finally start to see a glimmer of hope around Thursday the 17th, but it’s still just marginal. The wind eases slightly, and the swell holds, but it’s not until the morning of Friday the 25th that things really start to shift. The wind swings to a light cross-shore from the south-southeast, and the swell bumps up to 6 ft. The combined energy jumps to 1445 – moderate to strong – and the conditions start looking much more promising for a session.
Now, the real standout is the Sunday the 27th and Monday the 28th. This is the one to circle on your calendar. On Sunday the 27th afternoon, we see the swell jump to a solid 10 ft from the SSW, with a very long 20-second period. The combined energy hits a massive 6694 – that’s strong, powerful surf. The wind is a light cross-onshore, which isn’t perfect, but for a wave that size and that much energy, it’s going to be a proper, heavy reef break. This is expert territory only; 10 ft is big, and the long period will make it even more powerful and walled-up. It’ll be a challenging paddle, but the energy and shape will be there for those who can handle it. Monday the 28th morning holds similar size at 10 ft with a 17-second period, and the energy is still very high at 4391. It’s a long-range call, so don’t bet the house on it, but this is the window to be watching.
Crowds at Tandjung-Lefts can be an issue at times, but with these conditions, the crew will be out.
So, if you’re an advanced surfer, save your energy for that last weekend of September. The first week is a write-off, but the second week builds to a potentially epic, heavy finish.

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 Tandjung-Lefts 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.
