The Lowdown
G'day, Rusty here. Right, let’s have a look at what’s on the cards for Conchalio. We’ve got a run of small, clean conditions to start, but the real juice builds late in the outlook. The water is a touch warmer than normal for this time of year at 87°, so that’s a nice bonus.
First up, Monday the 14th sees a tiny 2ft SSW groundswell with a long 19-second period and glassy winds in the morning. It’s a beginner-friendly wave, but the energy is moderate at best (291). The morning is clean, but the afternoon turns onshore and messy. Not the day to rush.
Tuesday the 15th has a similar 2ft SSW swell in the morning, but the energy jumps up (548) and it’s clean with cross-off winds. A bit more push, still small. Afternoon gets choppy with cross-on wind.
Wednesday the 16th morning offers 4ft SSW swell with moderate energy (908) and clean, cross-off conditions. That’s a solid little window. The period is still long at 16 seconds, giving good shape, but it’s a beach break so those long-period lines might break a bit straight. Still, a fun session for intermediates.
Thursday the 17th morning is a gem: 4ft SW swell, glassy, clean, with moderate energy (670). That’s a sweet combo for a dawny.
Friday the 18th stays small (2ft, 20-second period) but the morning is dead glassy. The energy is moderate (520) and it’s a lovely calm start. The swell direction (SSW) isn’t the ideal W, but when it’s this clean, you take it.
Saturday the 19th and Sunday the 20th keep the small, glassy mornings going. Sunday the 20th actually bumps up to 3ft with strong energy (815) and glassy conditions – that’s a standout for the first week. The long-period (19s) SSW swell will offer nice lines, but again, at a beach break it might wall up a bit.
Monday the 21st through to Wednesday the 23rd sees similar 3ft to 3ft SW swells with clean mornings, but afternoon thunderstorms and onshore winds spoil the fun.
Now, the real standout hits on Saturday the 26th. We get a solid 8ft SSW swell with a 10-second period and glassy conditions all morning. The energy is strong (1331). This is a proper size, but it’s getting big for beginners – over 8ft later in the day, so this one is for experienced surfers only. Sunday the 27th is still pumping with 6ft to 7ft SW swell, though the afternoon gets onshore.
The biggest wave energy comes on Monday the 28th and Tuesday the 29th, with 7ft to 8ft SW swell, long 11-second period, and clean cross-off winds in the mornings. The energy is very strong (1355 to 2167). These are the top days for the entire outlook – big, powerful, and clean. But this is expert-only territory. The swell direction (SW) is off the optimum W, but the quality and consistency make it the highlight. Crowds are possible here at Conchalio, so get in early.
So, the best bet overall is the window from Saturday the 26th through to Tuesday the 29th, with Monday the 28th and Tuesday the 29th mornings being the absolute peak. The first week has plenty of small, clean fun, but the second week delivers the real punch.
Rusty.

Information about the Conchalio Surf forecast
The above surf forecast table for Conchalio provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Conchalio can be found by selecting the local surf guide option on the grey menu. Our Conchalio 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 (Conchalio) 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 Conchalio 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.
Conchalio is 2 km (1 miles) from the city of La Libertad. If you plan a holiday in El-Salvador - Costa del Balsamo, look for hotels and other accommodation in La Libertad. La Libertad has rooms for a wide range of budgets as well as car hire and transport links.
