The Lowdown
Alright folks, Rusty here. Let’s take a hard look at what Playa-Conchalio has in store for us over the next couple of weeks. It’s a bit of a mixed bag, so let’s get into it.
Right off the bat, Thursday the 20th is a write-off. The water is warm – about 87°, feeling a touch warmer than normal for this time of year – but the wind is a messy cross-on shore from the SSW at 12 mph, making the 2ft SW swell a chopped-up mess.
Friday the 21st morning, though, that’s where it perks up. The wind drops to a glassy 3 mph from the ENE, and you’ve got a clean 3ft SSW swell with a decent 11-second period. That’s a nice little window for the beginners – the wave energy is moderate (220) and the conditions will be smooth. The afternoon turns into onshore slop again, so get it while you can.
Saturday the 22nd morning is another glassy session, this time with a 3ft S swell and a 387 wave energy reading. Clean, small, fun for a log. The afternoon wind swings onshore again, though, so it’s a half-day affair.
Sunday the 23rd morning sees the swell period jump to 14 seconds, giving a long-period groundswell feel. The energy ramps up to moderate-high (502), but it’s a cross-shore wind. The waves will be there, but a bit bumpy. The afternoon gets onshore and messy.
The following week starts with some promising early-morning glass: Monday 24th, Tuesday 25th, Wednesday 26th, all with 3 mph or less wind from the east or north-east, and a consistent 2-2ft SSW swell. Not huge, but clean and surfable. The wave energy drops from 416 down to 156, so the juice isn’t there, but for a quiet morning paddle it’ll do.
Now, the real standout window is coming up. The morning of Saturday the 29th of August looks excellent. We’ve got a 5ft SW swell, period of 16 seconds, and glassy conditions with no wind. The wave energy is strong at 1109. This is a proper groundswell, and at Conchalio the long period might make it a little straight, but with the wind being dead calm, the quality should be fantastic. This one is for experienced surfers. Sunday the 30th morning is nearly as good – 5ft SSW, glassy, strong energy (1004).
The first few days of September keep the run going. Monday 31st and Tuesday 1st both have clean mornings with 4ft SSW swell, 14-second periods, and glassy wind. Very good conditions for a solid session. Wednesday 2nd morning is also glassy with a 4ft SSW swell.
Further out, Friday the 4th of September morning looks like the next big standout. We’re talking a 5ft SSW swell, 17-second period, and clean cross-offshore wind from the east at 9 mph. The wave energy is very strong (1851). That’s a lot of water moving for a more advanced crew. It’s over a week away, so keep a loose eye on it, but it has excellent potential.
For the best on offer, I’m calling Saturday 29th morning and Friday 4th September morning as the two top sessions. Both have that combo of bigger swell, clean wind, and high energy. Crowds at Conchalio can happen sometimes, so on those mornings, get out early.
Overall, this is a decent stretch. Lots of small, glassy mornings for beginners, and a couple of solid, proper days for the experienced crew. Stay patient, pick your mornings.
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.
