The Lowdown
G’day, it’s Rusty here.
Alright, let’s be straight with you. Looking at the next couple of weeks, it’s a pretty bleak stretch for Langs beach. We’ve got a long run of days where the surf is just too small and the wind is all over the shop. The first real bit of anything worth paddling out for isn’t until the 31st of August, and even then it’s not exactly classic. It’s a solid ten days or so of waiting through knee-high slop and cross-shore junk before we see any real size.
The good news is we’ve got two standouts. The first is the morning of the 31st. The swell jumps to a clean 5ft, coming from the NNE with a short 6-second period. There’s light ESE wind, and the energy is building—we’re talking moderate wave energy at 209. It’s still a short-period windswell, so it won’t be super lined-up, but it’s the cleanest it’s going to get for a while. The second standout is a day later, on the 1st of September. The swell is bigger at 6ft, still from the north, with a bit more energy behind it at 569. There’s a light NE wind, but it’s a touch onshore, and the period is still short at 8 seconds. It’ll be punchy and offering more power, but with that cross-on wind, you’ll want to pick your peaks. It’s a bigger swell, so this is definitely more for the experienced crew. With that kind of size and a beach break, it might be a bit much for beginners.
The water temp is sitting at 59 degrees when we finally get waves, which is about normal for this time of year, so you won’t need the thickest suit.
For the first standout, Langs beach is generally fairly consistent, so that helps. It’s exposed and picks up the north-east swell, which is what we’re getting. Expect the usual crew out there, so you’ll have some company. The second one, a day later, is still at Langs beach but the wind isn’t as clean.
The run-up to the 31st is rough. The 23rd and the 26th have some onshore junk with rain and chopped-up conditions. The 30th has more size but it’s messy with a cross-off wind at 15 mph. Not worth the paddle. Just wait for Monday morning.
The long-range stuff after the 1st looks like it drops back into the poor category, so keep your expectations low.
Signing off, Rusty.

Information about the Langs beach Surf forecast
The above surf forecast table for Langs beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Langs beach can be found by selecting the local surf guide option on the grey menu. Our Langs beach surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Langs beach) regularly then make a mental note of the wave energy from the surf forecast table each time you go. 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. 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.
