The Lowdown
G’day, Rusty here. Let's have a look at what's coming down the line for us at Langosta over the next couple of weeks.
Alright, straight up, the first week or so is going to be pretty underwhelming. We’ve got some small, weak swell around, but the wind and conditions just aren’t playing the game. It’s not until Sunday the 23rd of August that things start to look like they’re worth paddling out for.
Thursday the 20th is a write-off – poor surf with onshore and cross-onshore winds. Friday and Saturday won't be much better, with tiny 1ft to 2ft swell and cross-off or cross winds. You’ll get a few ankle-slappers if you’re desperate, but honestly, save your energy.
Finally, on Sunday morning the 23rd, we see a bit of life. The swell is still only 2ft, but it's coming from the SW with a long 19-second period, which is a proper groundswell. The morning has light cross-off winds from the ENE, keeping it clean. The afternoon gets even better – glassy conditions with a calm wind and a touch more energy (combined energy of 353). These are small, clean, and lined up, perfect for a longboard or a funshape with no one around. For the standouts? Sunday 23rd afternoon is the pick of the first week. The water temp is about average for this time of year, so a spring suit will be fine.
Monday the 24th and Tuesday the 25th keep the small but clean theme going with moderate offshore ENE winds in the mornings and light offshores in the afternoons. Reliable, but nothing to get too excited about.
Wednesday the 26th drops off a bit, and by Thursday the 27th the onshore winds return. That stretch is a skip.
Then we get a bit of a jump on Friday the 28th of August. The swell bumps up to 3ft with a long 19-second period, but the wind is a moderate cross-shore, creating a chop. The combined energy jumps up to 699, but it’s messy. Not a classic.
Now here’s the real action. Saturday the 29th of August sees the swell jump to 6ft from the SW with a 16-second period and moderate cross-off winds keeping it clean. The combined energy is strong (1515). That’s proper chest to head high swell with decent power, but the cross-off wind means it might be a bit lumpy. It’s only for the experienced crew.
Sunday the 30th of August is where it’s at for the whole run. The morning delivers 5ft SW swell with a 15-second period and a moderate offshore ENE wind, making for clean, lined-up waves. Combined energy is a solid 1042. This is excellent for experienced surfers. The afternoon also delivers 5ft with light cross-off winds from the SE and clean conditions. If you can handle the size, Sunday 30th morning is the standout of the entire outlook. Crowds are possible at Langosta, as it’s a consistent break.
Monday the 31st drops back to 4ft with clean morning winds, but the afternoon gets blown out by a cross-onshore. Tuesday September 1st has a glassy morning with 3ft swell – a nice little session if the swell holds.
Wednesday 2nd and Thursday 3rd of September see clean morning conditions with 2ft to 3ft long-period swell. Good for small-wave gear. Friday 4th of September finishes the run with a glassy morning and 4ft, 16-second SW swell, giving a combined energy of 732. This is a very good option to close out the forecast, but being so far out, it's promising but less certain.
Overall, the first week is a slow burner. The second week offers the real meat, with Sunday 30th August being the standout for experienced surfers and Sunday 23rd August afternoon being the best for a light, glassy session.
Rusty.

Information about the Langosta Surf forecast
The above surf forecast table for Langosta provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Langosta can be found by selecting the local surf guide option on the grey menu. Our Langosta 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 (Langosta) 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 Langosta 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.
