The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cooking at Conchalio.
First up, the water temp is sitting at 86°, which is a good degree warmer than usual for this time of year. That’s notable, so you’ll be in boardshorts or a thin spring suit for sure.
The opening window kicks off Sunday the 6th of September. Early morning on Sunday, we’ve got a clean 5ft SSW groundswell rolling in with a solid 15-second period, and the wind is glassy. The swell energy is moderate (940). This is a standout session. It’s a beginner-friendly break, so the size is right on the edge for learning, but the long period means the waves will have good shape. It’s exposed to the west, and even though the swell is from the SSW, it’s going to wrap in nicely. Crowds are possible here sometimes, but with conditions this clean, it’ll be worth the company.
The afternoon on Sunday goes onshore, so the surf gets a bit ragged. Monday morning the 7th brings it back—4ft SSW, 14 seconds, glassy again, with moderate energy (645). That’s another clean, fun session, but the swell is a touch smaller.
There’s a gap of a couple of days with smaller surf and mostly onshore afternoons, but the highlights keep coming. Tuesday morning the 8th is glassy with 3ft SSW, still a nice long period of 13 seconds. Wednesday the 9th is similar, glassy with 3ft. Then Thursday the 10th morning is a real standout: glassy, clean, 3ft SSW with a 17-second period, and the combined energy jumps up to 930. That’s a proper groundswell pulse, and the volume is there. This is the best on offer in the first week—perfect for a longboard or a funboard.
Friday the 11th morning is also glassy with 4ft SW, 16 seconds, and good energy (729). Another great morning. The pattern holds: mornings are gold, afternoons get blown out.
Moving into the second week, the consistency remains solid. Saturday the 12th morning is glassy, 3ft SW, 14 seconds. Sunday the 13th morning is glassy but smaller at 2ft. Monday the 14th has a glassy morning with 2ft but a very long 19-second period—that’s a groundswell that will wrap around the point here nicely. The energy is still moderate (367).
The real standout in the second week is Wednesday the 16th morning: glassy, 4ft SSW, 16 seconds, and strong energy (818). That’s a big, clean morning for Conchalio. Thursday the 17th morning is also glassy with 3ft. Friday the 18th morning is flat calm, glassy, with 2ft and a 20-second period—very long period, low energy (514), but if you’ve got a log, it’ll be fun.
The final call is Sunday the 20th morning: glassy, 3ft SSW, 19-second period, energy at 588. A clean, mellow way to end the run.
Overall, the mornings are the window. The first Sunday morning and the Thursday the 10th morning are the standout highlights. You’d be a fool to miss those. The rest of the week is a solid run of clean, glassy mornings with consistent SSW groundswell. It looks great for a beginner-friendly spot, but don’t sleep on that long period—it’ll make the waves stand up nicely.
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.
