The Lowdown
Rusty here again. Let’s break down the same stretch in imperial.
The only real swell window is the first couple of days, then the ocean takes a nap for about a week and a half.
Monday, August 17th is the clear standout. We’ve got a solid 6ft swell coming from the ESE, with a side-offshore southerly breeze at 15 mph making for clean, lined-up waves. The period is a touch short at 8 seconds, so the sets will be a bit more frequent and less grunty, but with moderate energy (482) and water temp about average at 60°, it’s a solid session for Langs beach. The offshore wind is gonna give you some nice, clean faces.
Monday afternoon keeps that same 6ft, shifting more east with a slightly longer 9-second period and lighter SSW offshore wind (577 energy). It might glass off even more. This is the best you’ll get for the whole 16 days.
Tuesday, August 18th the swell halves to 2ft, and even with the light wind, the energy drops hard (84). Small, but maybe a longboardable knee-knocker.
From Wednesday, August 19th all the way through to Saturday, August 30th, it’s a long, empty stretch. You’re looking at swell under 2ft for days, with most readings showing 1ft or less and energy values below 50. Even the glassy mornings on the 20th and 21st have barely a ripple at 1ft to 2ft. Not worth the wetsuit hassle.
Saturday, August 30th brings a tiny pulse from the NNE with 3ft and a 10-second period (148 energy), with a cross-offshore wind. Very ordinary, but at least you could get wet.
Monday, August 31st is similar – 3ft, NNE, with a southerly offshore (148 energy). Clean, but small.
The takeaway: hit Monday the 17th or you’re waiting more than a week for the next, much smaller, chance.
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.
