The Lowdown
Alright, Rusty here. Let's take a close look at what's shaping up for us over the next couple of weeks.
We’ve got one spot, Playa Conchalio, and it’s looking like a real nice run of surf is on the cards. The overall pattern is one of consistent, clean conditions with building swell, especially through the end of August and into the first week of September. The water temp is about average for this time of year, so nothing unusual there.
We get going on Sunday morning, August 23rd. It’s small, with 2.6ft of SSW swell, but the wind is glassy from the ENE at 3.1 mph. Combined energy is moderate (472). It’s a clean start for beginners given the size. The afternoon turns to junk with a cross-on wind, so make the most of the morning.
Monday the 24th and Tuesday the 25th follow a similar script: glassy mornings with 2.3ft of swell, and afternoons getting chopped up by a southerly breeze. The Tuesday morning is pure magic though – dead calm wind, glassy as a mirror, with a long-period swell (16 seconds) and 2.3ft of SW swell. That long period suggests better-shaped waves at this beach. Combined energy is moderate (324).
Wednesday the 26th sees an offshore wind in the morning, keeping things clean with 2.0ft waves, but the energy drops (186). Thursday 27th is similar with a glassy offshore start for 1.3ft, clean but small. The real standout in this first week is Friday morning, August 28th, with just a whisper of wind (0 mph, glassy) and 2.6ft of SSW swell at 16 seconds. The combined energy jumps to 636, and it’s a day for the longboard or a fun mid-length.
But the best on offer for the whole run has got to be Saturday morning, August 29th. It’s going to be pumping for a beach break. We’re looking at 4.6ft of clean SW swell, a very long period of 16 seconds, and absolutely dead calm conditions. The combined energy is cranking at 1186. That’s strong, powerful surf. At over 4.9ft, it’s not for the groms – this is for the experienced crew looking for a proper session. The afternoon gets messy, so it’s a dawn patrol special.
After a few days of slightly smaller but still glassy mornings (Sunday 30th to Tuesday 1st September), with swell around 3.6ft to 3.0ft, the next standout point is Friday morning, September 4th. This is a second push of energy with 4.9ft of SSW swell at a long 17 seconds. The combined energy is massive at 1597. It’s another morning of dead calm, glassy conditions. Again, this is big enough to be for experienced surfers only.
Saturday morning, September 5th, is also a banger: 5.6ft of swell with the same long period, zero wind, and glassy conditions. Combined energy is 1633. These are the biggest, cleanest waves of the outlook, but given the size (over 8.2ft? No, 5.6ft is under that but still serious), you’ll want to be confident in the water. The run continues with clean, glassy mornings into Sunday the 6th and Monday the 7th, with swell dropping back to 4.6ft and 3.6ft, but the quality stays high.
Overall, the mornings are where it’s at. The afternoons mostly get ruined by wind or cross-onshore conditions. The standout is Saturday morning, August 29th, and again the Friday and Saturday mornings of September 4th and 5th for the bigger, more powerful swell. Get on it.

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.
