The Lowdown
Alright, Rusty here. Let’s talk about what’s cooking at Lang Co over the next couple of weeks.
Honestly, it’s a pretty slow start. The first week is a real write-off with tiny, weak surf and iffy conditions. The first bit of hope shows up around Thursday, September 10, with a small pulse from the NE – not enough to get excited about. Friday, September 11, has a bit more size, but it’s onshore and messy. Then things finally start to turn around.
The real standout window begins Saturday, September 12. We get a solid 5ft groundswell out of the ENE, with a 9-second period and moderate wave energy (446). The real beauty is the wind: glassy in the morning, then clean offshore from the WNW in the afternoon. This is the best quality of the whole forecast. Lang Co is a sandbar break, and with that swell direction and offshore wind, it’s going to be clean and lined up. The water temp is sitting at 86°F with a positive anomaly of 0.9°, so it’s a touch warmer than average for the time of year – very comfortable.
We get a few more good days after that. Sunday, September 13, holds clean 4ft swell, but the wind is a bit stronger. Monday, September 14, bumps back up with 5ft to 6ft swell and clean conditions, with wave energy jumping to a very strong 707 on the afternoon. Tuesday, September 15, keeps the clean theme going with 5ft swell.
Now, the next big standout is Wednesday, September 16. The afternoon brings a powerful 8ft swell from the NNW with an 8-second period and huge wave energy (1885). That’s a lot of water moving – this is for experienced surfers only. The wind goes glassy, which is incredible for a swell this size, but that short period means it’ll be a bit sectiony and punchy. Best suited for the more competent crew.
Thursday, September 17, still has good size with 7ft to 8ft swell, but the wind is stronger cross-offshore, so it won’t be as clean as the 16th. By Friday, September 18, it’s dropping back to a cleaner 5ft. After that, the swell fades fast into the weekend of September 19-20, with tiny, weak waves and onshore winds. A bit of a flat finish.
So, to sum it up: the first week is mostly a dud. The best windows are Saturday the 12th through Tuesday the 15th for clean, manageable waves. And if you’re an expert, the afternoon of Wednesday, September 16, is a must-charge.

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.
