The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s coming down the line for Langosta.
First up, the water temp is sitting about average for the time of year, so no surprises there. The waves are small for the first few days, but don’t write it off yet. We’ve got a solid run of groundswell building, and the second half of the first week is where it starts to get interesting.
Wednesday the 5th is a bit of a washout. Tiny 2ft SW swell with a clean morning but a messy afternoon. Not worth paddling out for. Thursday the 6th is similar, with the swell holding around 2ft to 2ft, but the wind goes light offshore and glassy in the afternoon, so if you’re desperate for a splash, that’s your window. The energy is weak (125 to 110).
Friday the 7th is where things perk up. The swell jumps to 2ft to 2ft, but the period is a very long 18 seconds – that’s proper groundswell. The energy is moderate (444). The wind is cross-off, keeping it clean. This is a good sign of things to come.
Saturday the 8th is an early standout. The morning sees a 3ft SSW swell with a 16-second period, and a strong offshore wind from the ENE. The energy is solid (610). By the afternoon, it’s even better: the swell bumps up to 4ft from the SW, the wind drops to glassy, and the energy is still strong (516). That afternoon session is going to be pure, clean fun. The swell is still small enough for beginners, but the quality is there for everyone.
Sunday the 9th is a bit of a mixed bag. The morning gets hammered by a fresh 30 km/h breeze, which trashes the 3ft swell. The afternoon improves with a lighter wind, but it’s just “good,” not great. Monday the 10th is back to small and messy, with a cross-on wind in the afternoon.
Now, hang on tight for the second week. Tuesday the 11th delivers a clean 3ft swell with a moderate offshore wind in the morning, but the afternoon gets choppy. The energy is moderate (423).
Wednesday the 12th and Thursday the 13th are small, with the swell dropping to 2ft. The wind is mostly offshore or clean, but the energy is low (around 245). Worth a look if you’re keen, but nothing special.
Friday the 14th is a major standout. The morning is a bit windy, but the afternoon… wow. The swell hits 4ft from the SW, with a very long 18-second period, and the wind turns light offshore. The energy is very strong (1186). This is excellent surf, but that 4ft with 18 seconds of period means it’s going to be clean, powerful, and better suited to the reef and rivermouth sections of Langosta. This is the pick of the entire forecast.
Saturday the 15th keeps the swell solid at 5ft from the SW, with a 16-second period. The afternoon is the one to go for, with light offshore winds and very strong energy (1098). This is getting into the territory where it’s better for experienced surfers, but the quality is undeniable.
Sunday the 16th sees the swell drop a touch to 4ft, but the wind is fresh and cross-off, keeping it clean. The energy is still strong (677). Monday the 17th and Tuesday the 18th hold around 4ft, with the wind staying cross-off, but the energy drops back to moderate (around 420-476). Good, consistent waves, but the magic of the 14th and 15th is gone.
Wednesday the 19th is a small, clean morning with a 3ft swell and a light offshore, but the afternoon gets messy with a cross-on. Thursday the 20th wraps up the forecast with a small 2ft SSW swell and a very long 18-second period, but the wind is cross-off, and the energy is moderate (389). A clean, small day to finish.
Overall, the standout is Friday 14th August afternoon and Saturday 15th August afternoon for the best combination of size, power, and offshore conditions. The rivermouth and reef are going to be your friends for that long-period groundswell.
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.
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.
