The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s coming up for Langosta. This is a beach, reef, and rivermouth setup, and it’s a consistent little spot, so it’s gonna be giving us waves pretty much non-stop right through the next couple of weeks.
We’ve got a solid run of surf starting Monday the 7th. The water’s a touch warmer than normal for this time of year, sitting at 86°, so it’s a nice, comfortable paddle out.
Monday morning the 7th is a beauty. We’re looking at a clean 4 ft swell from the SW, with a nice long period of 14 seconds, and a light cross-offshore breeze from the NE at 6 mph. The wave energy is moderate (542). It’s a really good start, clean waves, and the kind of conditions that make you want to call in sick. The afternoon gets a bit iffy with a cross-on wind, so get on it early.
Tuesday the 8th and Wednesday the 9th have the same story: clean mornings with offshore winds (E at 9 and 12 mph) and solid SW groundswell dropping from 2 ft to 3 ft. The periods are very long, around 16 to 18 seconds, which is a classic groundswell. That long period means more energy and better-shaped waves, but at a rivermouth and reef setup, it’ll be just fine. The combined energy is moderate (625 and 674) but the quality is there. Afternoons get messy with the storms, so dawn patrol is the move.
Now, Thursday the 10th is the standout. The morning session is an absolute ripper: 4 ft of SW swell with a 17-second period, and a gentle offshore from the ENE at 9 mph. The wave energy bumps right up to a strong 1110. This is excellent for experienced surfers – it’s got push, it’s got shape, and it’s gonna be clean. This is the best session on offer without a doubt. Afternoon is a write-off with the cross-on wind.
The rest of the first week fades a bit. Friday the 11th and Saturday the 12th have smaller 3 ft to 4 ft surf, but the mornings are still clean enough for a fun paddle. The energy drops back to moderate (400-700 range). Sunday the 13th gets smaller again, with 2 ft, but that clean morning offshore wind makes it worth a look for a longboard or a foiler.
The second week starts quiet. Monday the 14th has a tiny 2 ft clean morning wave, but it’s a very long 19-second period. It’ll be small and slow. Things pick up again from Tuesday the 15th, with the swell rebuilding to 3 ft-3 ft, and good clean mornings with offshore winds. The conditions look promising. By Wednesday the 16th, we’re back to 4 ft with a glassy morning, which is a nice little bonus.
The real sleeper might be Friday the 18th. The morning is glassy – zero wind – with a 3 ft SW swell. That’s a rare treat, flat calm water, and even though it’s a shorter period, the conditions will be pristine. The weekend after that looks a bit messy with onshore winds and smaller surf, so the first ten days are where the main action is.
Overall, the best wave is hands down Thursday morning the 10th. That’s the one to circle. If you can’t make that, the clean mornings of the first week are all solid.
Stay stoked, and I’ll see you in the lineup.

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.
