The Lowdown
Alright folks, Rusty here. Let’s have a look at what we’ve got for Lang Co.
Right off the bat, I gotta be straight with you – we’re looking at a pretty bleak run of surf through this whole 16-day window. The charts are showing small, weak energy for the vast majority of the time, and when there is a little bump, the conditions just don’t line up well for a proper paddle session.
Starting now, it’s a long, quiet stretch. From Wednesday the 26th right through to Tuesday the 1st of September, we’ve got a whole week where there's barely a wave worth paddling for. The mornings see tiny, weak pulses of energy, with the combined energy reading often under 100 – that’s barely a ripple. We’re talking 0.3ft to 0.7ft swell at times, and the wind is all over the place, keeping things messy or just plain flat.
There’s a little spike of energy coming in on Tuesday afternoon, the 1st of September. Swell bumps up to 5ft from the NNW, with the combined energy hitting 220 (moderate). The wind is WNW 12 mph, blowing cross-offshore, which will keep the surface clean. But here’s the catch: that period is a super short 6 seconds. That’s windswell, not groundswell – it’ll be crumbly, weak, and pretty junky. The water temp is around 87°F, which is about average for this time of year for Lang Co. Honestly, with the size and the messy nature of that windswell, this setup looks a lot more interesting for kite surfing than for a standard paddle session. I wouldn’t get your hopes up for a classic wave.
The rest of the week into the weekend and beyond stays poor. Wednesday the 2nd has another pulse of NNW swell at 4ft with a 6-second period, but the energy is lower (180) and the 12 mph cross-offshore wind doesn’t save it from being poor quality. After that, it’s back to minimal energy and tiny waves for days on end. The latter half of the first week and the whole second week up to Thursday the 10th of September is a dead zone – zero surfable options showing up. Long period swell means nothing if there’s no swell to begin with.
So, the bottom line: there is no standout session here, not a single one I’d point you to as a must-go. The whole 16-day window is a bust. The consistent pattern for Lang Co is that when conditions are this poor, it tends not to stay bad forever, but this particular forecast is locked in for a long, quiet run. Better luck next week.
Rusty.

Information about the Lang Co Surf forecast
The above surf forecast table for Lang Co provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Lang Co can be found by selecting the local surf guide option on the grey menu. Our Lang Co 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 (Lang Co) 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 Lang Co 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.
Lang Co is 28 km (17 miles) from Da Nang. If you plan a holiday in Da Nang, look for hotels and other accommodation in Da Nang. Da Nang has rooms for a wide range of budgets as well as car hire and transport links.
