The Lowdown
Alright folks, Rusty here. Let’s talk about the next couple of weeks at Conchalio. This is a consistent little beginner-friendly spot, and while it’s not going to throw up any massive slabs, there’s a nice run of clean, rideable mornings coming our way. The water is sitting at 86°, which is pretty much average for this time of year, so no surprises there.
The pattern starts off a bit messy this afternoon, Monday August 10th. We’ve got a 3ft SSW swell pushing in, period around 13 seconds, but a cross-on wind from the south at 12 mph has things choppy and blown out. Not worth paddling out for this one.
The real window opens up on Tuesday morning, August 11th. It’s glassy as a mirror with a light northerly breeze, and that 3ft SSW swell (13 sec) will be clean and workable. You won’t need a gun, just a fun little log. The energy is moderate (367).
Wednesday morning, August 12th, is a standout. Dead calm, glassy conditions, and a solid 3ft SSW groundswell with a 16-second period. The combined energy kicks up to 501 (moderate). This long-period swell will hold up beautifully at this exposed beach break—expect some proper shape and long lulls between sets. It’s a good morning for beginners to get some practice.
Thursday morning, August 13th, is another glassy morning with that 2ft SSW swell (15 sec). Light and clean, energy around 343. Nothing huge, but fun.
Now, Friday morning, August 14th — this is the best on offer. The swell jumps to 4ft from the SW, with a long 18-second period. The combined energy hits 799 (strong). And it’s dead calm, glassy. That’s a recipe for some of the cleanest, most lined-up waves you’ll see in this window. It’s still manageable for beginners—nothing over 5ft—so it’s a great day to get out with a longboard.
Saturday morning, August 15th, the swell bumps up to 5ft from the SW, 16-second period, and again: zero wind, glassy. The energy is 964 (strong). This is solid for the spot, still beginner-friendly, but with some push behind it. Best for mid-lengths or hybrids.
Sunday morning, August 16th, the swell drops slightly to 4ft from the SW, 15-second period, and we’ve got light offshore winds from the NNE at 6 mph. Clean conditions. Energy at 667 (moderate). A good, cruisy morning.
From Monday, August 17th, right through the rest of the second week, the pattern settles into smaller, glassy mornings. Swell hangs around 2ft to 3ft, mostly from the SSW, with periods around 13 to 16 seconds. No big energies, but plenty of clean windows. The mornings of August 18th, 20th, 22nd, 24th, and 25th all show glass or offshore winds. It’s a slow, consistent run for a longboard or a foamie.
There’s a gap of a few days in the second week where afternoons get poor, but if you hit those glassy morning sessions, you’ll find something rideable. Nothing huge, but the consistency is there. Crowds at Conchalio are sometimes an issue, and because it’s such a friendly wave, it does get busy on clean days—so get in early.
This is Rusty, signing off.

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.
