The Lowdown
Alright, Rusty here, let's check out what's brewing at Langosta.
This spot's a consistent beach, reef and rivermouth that's wide open to the swell. The water's a warm 86°F, which is a touch warmer than usual for this time of year. Over the next couple of weeks, there are a few clear winners, but you'll have to pick your moments.
Thursday the 10th kicks off with a clean 4ft SW groundswell, but that cross-off wind from the ENE at 19 mph is a bit strong, and the energy is moderate (843). It's surfable but nothing special. Friday the 11th is similar, with a dropping swell and moderate cross-off wind in the morning.
Saturday the 12th morning is clean with a light breeze and a 3ft SW swell, but the energy is dropping (370). Sunday the 13th has a glassy afternoon with a tiny 2ft SW swell and a 13-second period. Small and clean, but not a standout.
Now, Tuesday the 15th morning is a proper standout. Clear skies, a gentle offshore ENE breeze at 9 mph, and a 3ft SW groundswell with a 15-second period. The energy is solid (518), and it's glassy. Crowds can be a thing here sometimes, so get out early. This is a log or mid-length dream.
Wednesday the 16th morning is another cracker. A 4ft SW swell with a 16-second period, light offshore ENE wind, and clean as a whistle. The energy is pumping (866). That's the best of the first week—smooth, punchy, and easy paddling.
The second week has a few OK mornings, like Thursday the 17th and Friday the 18th, but nothing that'll make you cancel plans. The real big boy move is Wednesday the 23rd morning. A solid 8ft SW swell, but the period is a short 8 seconds. The energy is strong (1341), and it's clean with a light cross-off breeze. That one's strictly for the experienced crew—way too big for beginners, and the short period means it'll be a bit wild and fast.
If I'm calling it, Tuesday the 15th and Wednesday the 16th are your best bets. Clean, offshore, good groundswell, and just the right size for a fun session. Don't sleep on it.
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.
