The Lowdown
Alright, surf’s up. Let’s get into it.
The Overall Picture
Okay, first things first. We’ve got a solid run of swell on the horizon here. It’s not going to be a week of pumping barrels, but there are windows where Langosta is going to be working, and looking clean. The energy in the water is moderate, with the combined swell energy readings mostly sitting in the 200 to 800 range, which tells you there’s enough push to make it fun out there.
The standout window looking ahead is the morning of Wednesday, September 16th. That’s the pick of the lot, with a strong 840 combined energy reading, a clean 4ft SW swell, and a gentle offshore ENE breeze. That’s as good as it gets for this stretch. The morning of Tuesday, September 15th is also a good one, with that very good surf condition tag, a 3ft SW swell, and a cross-offshore wind. Those are your two mornings to circle on the calendar.
The Day-by-Day
Let’s break it down, starting from today. Friday morning (Sept 11) has a 4ft SW swell with a 16-second period, but the forecast is marginal due to tide issues. The NE cross-off wind will keep it clean, but it just won’t have that spark. Friday afternoon gets a bit cross and messy.
Saturday, September 12th, the swell drops to 3ft. The morning is clean with a NE cross-off breeze, but it’s just not very big. You’ll get some fun little waves but nothing to write home about. The tide is still a question.
Sunday, September 13th, is small, only 2ft. It’s surfable, but just ordinary. The afternoon gets glassy with the wind dying off completely, but with that tiny swell, you might be on a longboard just to get a few.
Monday, September 14th, the swell is still small, around 2-2ft, but the period jumps up to 19 seconds. That’s some long-period energy. The morning offshore wind will clean it right up, and it might be worth a paddle if you’ve got a log. That long period will help it shape up on the rivermouth.
Tuesday, September 15th, is where things start to get interesting. The morning has a nice 3ft SW swell with a cross-off ENE wind, and it’s tagged as “very good surf conditions.” Get out there early. The afternoon gets blown out by a cross-onshore wind, so it’s a morning session.
The Standouts
As I said, Wednesday morning, September 16th, is the one. Langosta is looking at a 4ft SW swell, which is the biggest of the period, with a clean 16-second period. The wind is a light offshore ENE, so it should be glassy and clean. This is your best bet. It’s a beach, reef, and rivermouth setup, so that SW groundswell is going to wrap in nicely.
Thursday morning, September 17th, is also a cracker. The swell is a solid 3ft, but it’s the wind that wins here – a complete glass-off. It’s going to be clean and pretty. Another morning session.
Friday, September 18th, gets a bit messy. The morning swell is 3ft but not clean. The afternoon gets blown out with a moderate cross-onshore wind, and the poor conditions tag says it all. It might be a day to do something else.
The Second Week and Beyond
The weekend of the 19th and 20th is a bit of a mixed bag. Saturday morning is glassy with 2ft of long-period swell, so it could be fun on the right board. Sunday, the 20th, sees a pulse of energy jump back up to 3ft with a long 19-second period, but the wind is set to be onshore, which will junk it up. It’s a promise of energy, but the conditions might not cooperate.
Monday, September 21st, is onshore and lumpy, with a moderate breeze making things cross-chop. Not great.
Tuesday, September 22nd, the morning is worth a look. It’s glassy with a 3ft SW swell. That light air is a winner, and it’s one of the better calls for the second week.
After that, things get a bit trickier. There’s a stretch from Wednesday afternoon, September 23rd, through to Thursday, September 24th, where the wind picks up and it’s just messy and poor. That’s 1-2 days of not much.
It finally cleans up again on Friday, September 25th morning, with a light offshore and a small 3ft SW swell, and again on Saturday, September 26th morning, with a tiny 2ft but a 20-second period and clean conditions. Those are your promising long-range calls, but keep your expectations in check. It looks like some fun, clean small waves, but nothing big.
Alright, that’s the long-range look. Be smart, pick your windows, and I’ll see you out there.

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.
Langosta is 46 km (29 miles) from Nicoya. If you plan a holiday in Guanacaste, look for hotels and other accommodation in Nicoya. Nicoya has rooms for a wide range of budgets as well as car hire and transport links.
