The Lowdown
Righto, listen up. Rusty here, and I’ve been eyeballing the charts for Conchalio. This spot is a real treat for beginners—exposed to the west swell, and for the next couple of weeks, it’s serving up some seriously clean conditions if you pick your windows right.
We’ve got a stretch of small, long-period groundswell rolling in, mostly from the south-west and south-south-west. The water’s sitting at a warm 86°, which is a touch warmer than normal for this time of year. Now, the standout window kicks off Tuesday the 8th of September. The morning is looking prime: 3ft of swell from the SSW, a period of 13 seconds, and total calm—not a breath of wind. That’s glassy perfection for a learner-friendly wave. The combined swell energy is moderate at 572, so there’s enough push to be fun without being intimidating.
Wednesday the 9th morning is another beauty. We’ve got 3ft of SSW swell, a period stretching out to 16 seconds, and a glassy morning under a slight air. It’s clean as a whistle. Energy is a notch higher at 623. Thursday the 10th morning is where it really peaks for the week: 3ft of SSW swell with a 17-second period, glassy calm, and a combined energy reading of 930—that’s moderate energy but on the stronger side of it for the size. That’ll be some long, lined-up little runners. The Friday morning session on the 11th also looks solid: 4ft of SW swell, 16 seconds, glassy. You’d be mad to miss it.
There’s a gap in the top-tier quality after that. Saturday the 12th morning is still good with 3ft and a glassy start, but the afternoons start to get onshore and messy. From Sunday the 13th through to Monday the 14th, the surf dips down to 2ft, and while there are some glassy mornings, the energy drops off and the conditions get more ordinary or poor. You’re better off waiting.
The second week throws up some promising action, though it’s a bit further out so take it with a pinch of salt. Tuesday the 15th morning has a light offshore from the NNE, 2ft of long-period SSW swell, and clean conditions. By Wednesday the 16th morning, we’re back in the groove: 4ft of SSW swell, 16 seconds, and glassy. Energy is 738. Thursday the 17th morning also brings clean, offshore conditions with 3ft of swell. And then keep an eye on Sunday the 20th and Monday the 21st. Both mornings and even the afternoons on the 20th are showing 3ft of SSW swell with a 19-second period and clean, cross-offshore winds. The energy builds to 787 and 893 respectively—moderate to strong energy, and those long-period waves will wrap in nicely here.
If I had to call the absolute best of the lot, it’s hands-down Tuesday the 8th and Thursday the 10th mornings. Glassy, small, clean, and forgiving. The only thing to note: with a 4ft swell on the 11th and 16th, it’s still fine for beginners, but the longer period means the sets will be spaced out. The crowds can turn up here sometimes, so get your session in early.
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.
