The Lowdown
Alright folks, Rusty here. Let’s talk about what’s happening over the next couple of weeks.
We’ve got a slow start, but the back half of the outlook is looking much better. The first solid session kicks off this Sunday morning, the 30th of August, with a clean window. The week ahead has a few build-ups, but the real standout is going to be Friday the 4th and then again that Thursday the 10th of September. There’s a noticeable gap in quality surf after the first Sunday, with a few days of smaller, cleaner conditions mid-week before the energy really picks up.
Right, let’s get into it. Our main spot is Conchalio. The water is sitting at 86°F, which is pretty normal for this time of year, so no surprises there.
The first real green light is Sunday morning, the 30th. It’s glassy, clear skies, with an ESE breeze at only 3 mph. Swell is coming from the SW at 5 ft, period 14 seconds – that’s a solid groundswell with plenty of push. Combined energy is moderate at 865. It’s not massive, but it’s clean and the optimum swell direction is W, so we’re close. Expect good, clean lines. The afternoon gets a cross-on, so I’d be in the water early.
Monday morning, the 31st, is glassy again, but the swell has dropped a bit to 4 ft (SW, 13s). Energy is down to 472. Still clean, still fun, but smaller. The afternoon turns cross-on and choppy, so it’s a morning mission.
Tuesday morning, the 1st of September, is clean with a cross-off breeze from the ESE. Swell is 3 ft from the SSW at 13s. Energy is weak at 386. It’s okay, but you’re not going to get blown away.
Wednesday morning, the 2nd, is glassy again with a 3 ft SSW swell (13s). Energy is moderate at 605. Another clean, small morning. The afternoon has the wind turning onshore.
Thursday morning, the 3rd, is dead calm and glassy. Swell is 3 ft from the SSW but with a very long 16s period. Energy is moderate at 520. That long period means it’s best for a point or reef setup – this is a beach break, so it might get a bit wally. The Thursday afternoon is actually better: glassy with a 4 ft SW swell (15s) and energy of 777. That’s a nice little session.
Now, the big one. Friday morning, the 4th of September. This is the standout. Calm, glassy, some clouds. Swell is 5 ft from the SSW with a 17-second period. Combined energy is strong at 1353. This is excellent surf for experienced surfers. The 5 ft afternoon gets a cross-on, so again, the morning window is the pick. This is a real highlight.
Saturday morning, the 5th, has a cross-on and a 6 ft SSW swell (16s). Energy is strong at 1394. That’s getting solid, but the wind is off. If you’re a kiter, the setup here with that size and cross-wind might be more interesting than paddleboarding.
After a few choppy days, the next gem is Thursday morning, the 10th of September. Glassy, calm-ish, with a 5 ft SSW swell and a 17s period. Energy is strong at 1133. Another excellent session for experienced surfers. The long period is a bonus for the points.
The rest of the run into the second week has some glassy mornings but smaller swell – the 12th and 13th have 3 ft and 3 ft swells, and the 14th is a tiny 2 ft but with a very long 19s period. That’s clean but small.
So, to wrap it up: the best windows are Friday morning the 4th and Thursday morning the 10th of September at Conchalio. Get in early and enjoy the clean, glassy conditions with a solid SW groundswell.
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.
