The Lowdown
Alright gang, Rusty here again. Let's talk about the surf in proper feet and miles-per-hour.
So, the first few days ain't looking too flash. The wind is a steady cross-on from the ESE or SE, blowing at 9 to 12 mph, sometimes gusting to 15 mph. It’s messing up Tandjung-Lefts. There’s swell, coming in at 5 to 7 feet from the SSW, but the onshore breeze is making it choppy and messy. The water is about 80°, which is normal for the season. The combined energy is high, between 1360 and 2969, but with that wind, it’s a lot of wasted energy.
We’re in a bit of a lull until Monday, August 10th. That afternoon, the swell picks up to 8 feet from the SSW, with a long period of 18 seconds, giving us a solid 4574 in combined energy. The wind is still cross-on at 12 mph, but you can feel the energy building. It’s still a bit rough, but it’s the first real window.
The big standout is shaping up for Tuesday, August 11th. The morning shows a solid 10-foot SSW groundswell, with a period of 17 seconds and a massive 4513 combined energy. That’s a serious amount of water. For Tandjung-Lefts, a reef break, this long-period groundswell from the south is perfect. The wind is still cross-on, so it won’t be glassy, but this is powerful, heavy surf. Over 8 feet, this is for experts only. The crowd here is sometimes a factor, so expect some company.
The run continues through Wednesday, August 12th, with the swell shifting a bit more southerly, still holding 7 feet in the morning, and then we get another big pulse on Wednesday, August 19th. That afternoon, we’re looking at another 10-foot SSW swell, with an 18-second period and a massive 5464 combined energy. The wind is a little lighter, only 9 mph, which helps, but it’s still cross-on. That’s a long-range call, so it’s promising but keep an eye on it.
For the best of the bunch, I’d say the morning of Tuesday, August 11th is your best bet – that’s the biggest, most powerful, and most consistent window. The afternoon of the 19th is a close second, but it’s further out, so less certain. This reef loves those long-period SSW swells, even with the wind. Just get your timing right.
Rusty.

A general guide to surfing at Tandjung-Lefts can be found by selecting the local surf guide option on the grey menu.

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.
