The Lowdown
G'day, Rusty here. Look, I'm not gonna sugarcoat it – this next couple of weeks is a real grind for surf. We've only got one spot on the cards, and it's not exactly going to be pumping. The forecast is for Tandjung-Lefts, and it's a consistent, advanced-level reef break that's fairly exposed to the swell. The water temp is sitting about average for this time of year.
Right off the bat, Tuesday the 8th of September is a write-off. Solid 5ft to 6ft SSW groundswell packing some serious energy (2582-3049) – that's proper power – but it's all cross-on and choppy. It looks more interesting for a kite session than a paddle.
Wednesday the 9th of September sees the biggest swell of the run, hitting 8ft from the SSW at 16 seconds. That's a heavy groundswell for this place. The energy's still massive (2846), but it's just messy. For a reef break, that cross-on wind is a killer. It's not going to be pretty.
Honestly, the whole first week is a blur of cross-on wind and marginal conditions. The swell hangs around 5ft to 7ft from the SSW, but it's permanently messy. There's a 15-second period on the 10th and 11th, which would normally be an exciting long-period groundswell, but the wind just ruins it. It's a hard pass until things settle down.
The only real standout, and I use that term loosely, is the very end of the forecast. Heading into the 23rd of September (Wednesday), we see a pulse of long-period groundswell hitting again, 5ft from the SSW at 18 seconds. The energy jumps back up (2387), and while the wind is still cross-on, it's just a light breeze. It's promising but less certain being over two weeks out. For this part of the world, that combination of a long-period groundswell and lighter wind on a reef is the best offer you're going to get, so keep an eye on it.
Otherwise, this is a real flat spell. Days of 12th to the 22nd are mostly poor with only tiny windows of marginal surf. A few days in there, like the 15th and 16th, are complete blanks. For this area, that's a pretty normal run of luck.
Rusty.

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.
