The Lowdown
Alright folks, Rusty here. Let's have a look at what the ocean's got cookin' for us at Langosta over the next couple of weeks. It's a bit of a slow start, but there's some real firepower coming down the line.
We've got a stretch ahead that starts off small and builds into something special. The first few days are a tease, with small clean waves for the beginners and longboards, but the real meat is further out. This is a beach, reef and rivermouth setup exposed to the west-northwest, so she needs the right swell direction to really light up.
The wait is on for the end of August. The first real standout is shaping up for the morning of Friday the 28th. The swell jumps to 3 ft from the southwest with a long, juicy 19-second period. That's a proper groundswell with real energy behind it (706). The wind's going to be light cross-offshore, so the waves should have some nice shape to them. It's not huge, but the quality looks excellent for a session on the bigger boards.
But if you're an experienced surfer, circle the morning of Saturday the 29th. That's the pick of the whole run. We're looking at a solid 5 ft of southwest swell, still with decent 16-second period, and the wind is straight offshore from the east-northeast. The combined energy is cranking (1237), and the conditions are set for clean, powerful waves. This is definitely one for the lads who know what they're doing.
The good energy keeps rolling into the next week. The morning of Monday the 1st of September has a clean 3 ft swell with light offshore winds. Not a standout, but a solid day. Then the end of the first week of September brings more size. The morning of Saturday the 5th of September shows a 6 ft southwest swell with an offshore breeze. That's a big, powerful day (1707) suited only for the experienced crew.
A word on the water: it's feeling about average for this time of year around Langosta, so no need to dig out the thickest wetsuit just yet.
Take care of that Thursday morning the 3rd of September. There's a 2 ft swell with a super long 20-second period from the southwest. That long-period groundswell is going to be breaking pretty straight and fast on a beach break setup, so keep your wits about you. It might be better for the rivermouth or reef sections if they're working.
Overall, we've got a slow warm-up, a real standout on the 29th of August, and a few more solid days for the experienced surfers in the first week of September. The second week is more of a waiting game with smaller, cleaner options.
Stay stoked, 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.
