The Lowdown
Alright, Rusty here, let's talk about what's on the cards for our local stretch.
We've got a solid run of surf ahead at Langosta, with only a bit of a wait for things to really fire up. The water is sitting at 86°, which is a solid 4° warmer than usual for this time of year, so it’s going to feel like a warm bath out there.
The first few days, Sunday the 13th and Monday the 14th, are more about getting a wet suit on than getting anything special. Small 2ft SW swell with moderate energy (around 191), and while the morning winds are clean and offshore, it's just not got the push. Monday afternoon sees a glimmer of hope with the wave comment picking up, but it's still small.
Things start to change on Tuesday the 15th. The morning has a 2ft SW groundswell with a period of 18 seconds and building energy (515). That long period is great for a reef setup like this, but it might make the waves a little straight at times. Still, gentle offshore winds should keep it clean.
Wednesday the 16th morning is a real standout. We're looking at a 4ft SW swell with a solid 16-second period and combined energy cranking up to 830. That's moderate to strong energy. The wind is gentle and offshore from the ENE, which is perfect for keeping the face smooth. This is the best on offer in the first week—a proper session for intermediates and above. It's a bit much for beginners though at that size.
The rest of the first week has some good morning windows, like Thursday the 17th with a 3ft SW swell and moderate offshore wind, but the afternoons get a bit messy with onshore breezes.
Looking further out, the real highlight pops up on Saturday the 26th. The morning session brings a solid 7ft SW swell with strong energy (1612) and a moderate offshore breeze. This is big and powerful, definitely for experienced surfers only. It's a long-range call, so keep an eye on it, but if it comes together, it'll be the standout of the entire outlook. The afternoon drops off quickly with a smaller, cleaner 3ft swell.
The run of mornings from the 20th to the 24th also offers some nice, clean 3ft to 4ft SW swells with glassy or offshore winds, perfect for a longboard or a funboard. Crowds at Langosta can be a problem, as it's often busy, so getting out early is the key.
There's a consistent run of surf here, so don't let the quiet start put you off. The forecasts can always change for the better.
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.
