The Lowdown
Hey crew, Rusty here with the lowdown on your local surf.
The long-range picture is pretty consistent but tough. There's a constant, solid south-southwest groundswell, but the wind is blowing from the wrong direction, keeping things choppy for the better part of two weeks. You're gonna need to pick your moments.
We've only got one break in the mix, Tandjung-Lefts, a consistent advanced reef that handles south swell like a champ.
Starting from Wednesday, August 19th, we've got a strong 8ft SSW swell with that nasty cross-onshore wind. The same story holds true through to the end of August. The swell stays solid – between 5ft and 8ft – with long, 15 to 17 second intervals, which is prime groundswell. But a persistent cross-onshore breeze of 9 to 16 mph is keeping the surface messed up, creating a lumpy, choppy ride. Saturday the 22nd is a particular low point with stronger winds.
The one clear winner, the session you should be aiming for, is Friday, August 28th. The wind finally relents and goes light cross-shore. The swell is still a meaty 7ft from the SSW with a 16-second period. This will be the cleanest the wave looks for the entire forecast. It's not perfect, but it's the best we're going to get.
Looking further ahead to Monday, September 1st, another big pulse of SSW swell hits, around 7ft with a 17-second period and a ton of energy. The wind might try to improve, but it's still forecast to be cross-onshore. It's a potential gem if it cleans up, but the long-range forecast means we'll have to wait and see.
Water temp is a comfortable 80°F, right where it should be for this time of year. Crowds at Tandjung-Lefts are listed as "sometimes," so expect some company on the good days. Just a heads up, with the swell between 5ft and 8ft for most of the time, this is strictly for experienced surfers. It’s been a bit of a battle with the wind, but there's a light at the end of the tunnel on the 28th.
Stay stoked, 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.
