The Lowdown
Alright, let’s talk about Langosta. This spot is a mix of beach, reef and rivermouth, consistent as they come, and open to a west-northwest swell. Water temp is about 86°F, a touch warmer than usual for this time of year.
Right now, it’s sleepy. Friday the 17th has a tiny 1ft SW groundswell with a 15-second period, but a fresh cross-off breeze is blowing. It’s clean, but there’s hardly any power. Combined energy is only 142, so it’s weak.
Through the weekend and into the new week, the swell stays small, mostly under 3ft, with long periods that make the waves fat and sluggish. Winds are cross-off or offshore, keeping things clean, but the energy stays moderate at best, in the 200 to 400 range. Not much to write home about.
Late on Wednesday the 23rd, we get a small 1ft SW groundswell with a 26-second period and 382 energy, but the real standout starts around Thursday the 24th of July. Friday morning the 24th brings a 3ft SW groundswell at 24 seconds, energy jumps to 853, with a gentle cross-off breeze. It’s small but clean and shapely—good for a log.
Saturday morning the 25th is promising: 3ft SW at 21 seconds, light offshore wind, and very good conditions expected. Energy hits 944, which is decent for the size.
Now, Sunday the 26th of July is the real gem. Morning is glassy, 4ft SW at 19 seconds, energy at 938. By afternoon, still glassy with 4ft SW at 18 seconds and energy pushing 1307. That’s strong and smooth—the reef will be working, and the rivermouth should have some beautiful lines. No wind, just clean, rolling surf. This is your best bet of the whole outlook.
Monday the 27th holds size at 4ft SW with 18 seconds but the wind picks up to a moderate cross-off. Still surfable, just not pristine.
Tuesday the 28th of July is another stand-out for the experienced crew: 5ft SW groundswell at 18 seconds, energy at 1527—very strong—with clean conditions and light winds. That’s a proper swell, so only for those who know what they’re doing. Afternoon gets a bit ragged.
After that, things ease off into early August, with occasional glassy windows but nothing that touches that Sunday the 26th or Tuesday the 28th. Crowds are a regular thing here, so expect company.
First week is quiet. The good stuff kicks in around the 24th and peaks on the 26th and 28th. Go get it.

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.
