The Lowdown

Alright folks, Rusty here. Let’s chew the fat on what’s coming for our local breaks.

We’ve got a solid run of surf coming up, but it’s not all game on from the start. There’s a bit of a gap before the first proper window opens. The first real action we’re looking at kicks off Friday the 14th, but the conditions are a bit fiddly. The energy is there, with a long-period SW groundswell around 4ft pushing in, but the wind is a fresh cross-offshore, making it tricky. The wave energy is moderate (901). It’s a bit of a marginal call for the Friday morning session.

Friday afternoon cleans up a little, the wind swings lighter, but the swell is still just 4ft. The energy jumps up to a more moderate 1132, but honestly, it’s not the gem of the run.

The real standout for this first week is Sunday the 16th. The morning is looking magic. We’ve got a clean 4ft of SW groundswell, with a gentle breeze coming from the NE. The wave energy is sitting at 677, and the forecast says to expect very good surf. The period is 15 seconds, so it’s a proper groundswell with good shape. This is a beach, reef, and rivermouth setup, so that long period should wrap in nicely. The water temp is about average for this time of year.

Monday the 17th is another beauty. The morning has a light offshore wind from the ESE, with a clean 4ft swell. The real gold is the afternoon though—glass. Absolutely glassy conditions with a 4ft SW swell. That’s the kind of session you wait for. The energy is moderate (500).

After that, the swell starts to taper off from Tuesday the 18th onwards. The mornings are still clean with small waves, but the afternoons get blown out by onshore winds. We’ll see a few fun, clean mornings, especially on the 19th and 20th, with very small waves around 2ft to 3ft, but nothing to get too excited about.

There’s a bit of a dry spell from the 21st through to the 27th. The waves drop right off into the 2ft range. The morning windows are clean, but the energy is low (down to 115). It’s surfable, but very ordinary. The 23rd sees a spike in period (19 seconds) on a tiny 2ft swell, which is promising for a really clean, peelable wave if you’ve got a log, but the size is just not there.

The forecast then starts to look up again on Friday the 28th. A new pulse of SW groundswell is expected, pushing back up to 3ft with a 16-second period. The wind is a brisk cross-offshore from the NE, so it’ll be clean. The energy is back up to 490. It’s a week away, so don’t book the time off yet, but it’s a promising end to the outlook.

So, to wrap it up: The Sunday morning (16th) and Monday afternoon (17th) are your absolute best bets for this entire stretch. Classic, clean, glassy conditions with a solid long-period groundswell.

Stay stoked.

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.
