The Lowdown
Alright, listen up. Let's break down what's shaking at Langosta. This spot is a consistent beach, reef, and rivermouth that loves a good WNW swell. The water is a warm 86°F, which is a touch warmer than usual for this time of year.
The first real standout is Friday, September 4th. The morning is your best bet. Swell is a solid 5 feet from the SW, with a long 17-second period pushing a ton of energy (1443). That's a powerful groundswell. The wind is blowing straight offshore out of the east-northeast, so it's gonna be clean and lined up. This is proper surf for experienced folks – it's got some punch. The afternoon turns sloppy with a cross-on wind, so get it early.
Saturday the 5th is another morning session. The swell holds at 6 feet from the SW, still a long 16-second period (1459). A light easterly offshore breeze will keep it clean. Good waves for the experienced crew. Afternoon gets messy again.
Sunday the 6th is a bit smaller, 5 feet SW, but the period drops to 14 seconds. Still, morning offshore winds mean clean shoulders. The energy is moderate (862). A fun, manageable size.
Monday the 7th sees the swell dropping to 4 feet, but the wind is clean. Tuesday the 8th is a real treat – the morning is clean, and then Tuesday afternoon looks glassy with a 2-foot swell from the SW and a 17-second period. The energy is lower (514), but for a glassy, long-period wave, it'll be a dream for a longboard.
Wednesday the 9th is a beauty, too. Morning is clean, and the afternoon turns glassy again with a 4-foot swell. That's a sweet, clean window.
We hit a lull from Saturday the 12th through to Monday the 14th. The swell drops below 3 feet, and the winds get messy. The energy is low (227-421), and it's a quiet patch. The longer period on the 14th (19 seconds) hints at something building.
The surf picks back up on Wednesday the 16th. The morning shows a 4-foot SW swell with a 16-second period (726) and a light offshore wind. That's a solid return. Thursday the 17th morning is glassy with a 3-foot swell – a perfect, clean morning.
The long-range highlight is Friday the 18th. The morning is looking glassy with a 3-foot swell from the SW, but the period... 21 seconds! That's a massive, long-period groundswell. The energy is moderate (738), but the wait between sets will be worth it. This is a classic point-break wave, and with glassy conditions, it's a real standout. Just keep in mind it's a long-range call, so it's promising but not set in stone.
Saturday the 19th looks a bit rough, so aim for that Friday morning.

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.
