The Lowdown
Alright, Rusty here, and I’m looking at the 16-day picture for Langs Beach. Let me tell you, it’s a bit of a slow burner, but there’s a couple of bright spots if you’re patient. The water is sitting at 60°F, which is pretty much normal for this time of year, so no surprises there.
The first week is mostly a bit of a non-event. We’ve got a few windows, but nothing that’s really going to get the heart racing. Saturday morning, the 15th of August, is the first real chance, with a 4ft easterly swell and a 7-second period. The combined energy is weak at 221, and with a cross-off breeze from the SSW, it’s clean but small. It’s a beginner-friendly option, but don’t expect much power.
Then we hit a bit of a lull. Sunday the 16th drops to 3ft, and Monday the 17th actually brings a bit more size – 6ft from the ESE on Monday morning, with a moderate energy of 528. The wind is offshore, which is a big plus, but the period is short at 8 seconds, so it’s a bit bumpy. It’s a marginal call, but for the more experienced among us, it could be worth a look. The afternoon is cleaner with a 5ft ESE swell, period up to 9 seconds, and a moderate offshore wind. It’s not epic, but it’s the best of a fairly average bunch in that first week.
After that, the surf drops right off. From Tuesday the 18th all the way through to Friday the 28th of August, it’s a long, quiet stretch with waves mostly under 2ft. There’s a few tiny pulses, but nothing rideable. It’s a proper dry spell for paddle surfing.
Now, the real interest comes right at the end of the forecast. Saturday the 29th of August shows a 8ft NNE swell, with a 9-second period and a combined energy of 985 – that’s moderate to strong, and it’s a big one. The wind is cross-off from the ESE, keeping it clean, but at 8ft, this is strictly for the experts. It’s a bit of a beast. Sunday the 30th drops to 6ft but still has solid energy at 932, with a 9-second period. It’s more manageable, but still a powerful, clean wave. The optimum swell direction is from the NE, and this NNE swell is pretty close, so Langs Beach will be working well.
If I had to pick the standout, it’s got to be Saturday the 29th of August. That 8ft NNE swell with clean cross-off wind is the biggest, most powerful swell of the whole period. It’s a proper groundswell, and while the period isn’t super long, the energy is there. Just be ready for a serious session – it’s not for the faint-hearted.
Rusty.

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 Langs beach 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.
