The Lowdown
Alright, Rusty here. Let’s have a look at what’s cooking for the next couple of weeks.
We’ve only got one spot worth talking about, and that’s Langosta. It’s a beach, reef and rivermouth setup that’s consistent and exposed to the west-northwest. The whole 16-day window is a bit of a slow burn, so you’ll need patience, but there are a couple of moments that’ll make it worth paddling out.
The first standout is Sunday the 16th. Morning glasses off with a dead calm wind and the swell sits at 4 ft from the SW with a period of 15 seconds. That’s a solid groundswell, and the water temp is about average for this time of year. Combined energy is moderate, coming in at 606. This is the cleanest you’ll have it—glassy waves, proper shape, and the crowds at Langosta can be often, so you might want to get there early. By the afternoon, it stays clean with a light cross-off breeze and the same 4 ft SW swell. That’s a full day of fun.
Monday the 17th is also promising. The morning holds 4 ft SW at 14 seconds, with a cross-off breeze. By the afternoon it goes glassy again, and the combined energy ticks up a notch to 526. That’s the kind of session where you can get into a rhythm.
After that, the swell slowly fades through the week. From the 19th onward the heights drop to under 3 ft, and the winds get a bit messy in the afternoons. There’s a gap from around the 21st to the 22nd where the mornings are small and the afternoons are cross-on. Nothing to write home about.
A little promise pops back up on Sunday the 23rd of August with a 2 ft SW swell but a period of 19 seconds—that’s a very long period groundswell. It’ll bring clean morning conditions if the cross-off holds, but the size is small and the energy is still weak, only 284. Then Monday the 24th has offshore wind in the morning and the same small 2 ft southerly groundswell. Worth a look if you’re desperate.
That’s the story. A few glassy windows and some proper groundswell shape, but overall the energy is moderate and it’ll be small by the second week. Keep your eyes on Sunday the 16th and Monday the 17th.
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.
