The Lowdown
G’day, I’m Rusty, and here’s how the surf’s lookin’ for your local stretch.
We’ve got a solid run of waves comin’ through, with a real standout session on the way that’ll have you frothing. The early mornings are where it’s at, with clean conditions and glassy surfaces. The first week is a slow burn, then it really fires up into the second week, especially for the experienced crew.
Let’s kick it off. Tuesday morning, August 25th, is a beauty right out of the gate. The swell is 2ft from the SW, with a long period of 16 seconds. It’s gonna be glassy, with a light NNE breeze at 3 mph. The combined energy is moderate (337). This is a true standout for clean, fun waves on the long period groundswell. Perfect for a beginner-friendly spot like Conchalio, but be aware that long period swells can break a bit straight at a beach, so look for the bank.
The afternoon glass is a bit blown out by a cross-on S wind, not worth paddling out for.
Wednesday morning, August 26th, is glassy again, with a 2ft SSW swell at 15 seconds, but the energy is low (156), so it’s just ordinary. Thursday morning, August 27th, is glassy but the swell drops to 1ft, though the period is a very long 18 seconds. Energy is moderate (230). It’s a clean, quiet session for a slow cruise.
Friday morning, August 28th, is where the energy picks up. Clean, glassy conditions with a 3ft SSW swell at 16 seconds. The combined energy is strong (636), and this is a real treat. The waves will have some push. The afternoon gets cross-on, so don’t bother.
Saturday morning, August 29th, gets seriously interesting. The swell jumps to 5ft from the SW, period 16 seconds, with a light cross-off ESE wind at 3 mph. The energy is very strong (1076). This is excellent for experienced surfers—the waves have real power. The water temp is about average for this time of year, nothing unusual. It’s clean, but that 5ft is getting a bit much for beginners.
Sunday morning, August 30th, is glassy with 5ft from the SW, period 14 seconds, and strong energy (767). Good fun, but the afternoon gets destroyed by an onshore SW wind.
Monday morning, August 31st, is glassy with a 4ft SSW swell (444 energy). Decent but nothing special.
Tuesday morning, September 1st, is clean with a cross-off wind and 3ft SSW swell (421). Fair.
Wednesday morning, September 2nd, is glassy again with a 2ft SSW swell but a very long 18-second period. Energy is moderate (500). Good for a chill session.
Thursday morning, September 3rd, is glassy with 3ft SSW swell at 16 seconds (513). Nice, clean lines.
Now, here’s the absolute standout. Friday morning, September 4th. The swell hits 6ft from the SSW, period 17 seconds, with a light offshore NE wind at 3 mph. The combined energy is massive (2018). This is big, powerful, clean groundswell for experts only. Over 8ft it’s for experts, but at 6ft it’s still a serious step up. The direction matches the break’s optimum. This is the best session on offer, but it’s more than a week away, so keep an eye on it.
Saturday morning, September 5th, is glassy with zero wind, and a 6ft SSW swell at 16 seconds (1452 energy). Another excellent, clean session for experienced surfers.
Sunday morning, September 6th, is glassy with 4ft SW swell (614 energy). Good fun.
Monday, September 7th, is glassy with 4ft SW swell (468). Decent.
Tuesday, September 8th, sees glassy conditions in the morning with 3ft SSW swell (544), and even the afternoon looks clean with a cross-off wind and 3ft swell (527). Both sessions are solid.
Wednesday morning, September 9th, finishes the run with a glassy 3ft SSW swell (681). Good energy.
Overall, the early mornings are the key. The best on offer is Friday September 4th and Saturday September 5th for the experienced crew, with massive energy and clean conditions. The water temp is just average for the time of year.
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.
