The Lowdown
Alright, Rusty here again. Let’s break down the next couple of weeks.
First few days are a bit dead. The wind is messy and the swell is small, so you’re not missing much. Better to wait it out.
Things start to get interesting around Friday the 24th. That morning at Langosta, we’ve got a 3ft swell from the SW with a very long period of 24 seconds. The wind is offshore from the NE, so it’ll be clean. The combined energy is strong (852). This is a real standout. The swell direction isn’t bang on the optimum, but with that period and clean conditions, the waves will be well-shaped and lined up. It’s a consistent spot, so you’ll get plenty of waves. The water is a touch warmer than normal at 86°, which is nice.
The real highlight though is Sunday the 27th morning. Swell is up to 4ft from the SW, period at 16 seconds, and the wind is a clean offshore from the E. The combined energy is 1380 (strong). That’s excellent for experienced surfers. Then Tuesday the 28th morning is glassy with a 5ft SW swell at 18 seconds and energy at 1645 (very strong). This is the one to circle on the calendar. It’s getting into the size range where it’s for experienced folks only, but it’s going to be epic.
The swell drops a bit after that, but there are still clean, fun mornings through the end of July and into early August. The first Monday in August (the 3rd) has a clean 4ft SSW swell with a light offshore and moderate energy.
Best bets: Friday the 24th morning for the long-period lines, and Sunday the 27th through Tuesday the 28th for the bigger, cleaner groundswell. Watch the afternoon wind shifts.
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.
