The Lowdown
Alright, Rusty here. Let's talk about what's coming up for our local stretch of coast.
Right off the bat, we’ve got some clean, small waves to get things started. The forecast kicks off with a solid run of surf, but you’ll want to pick your moments as the afternoons tend to get a bit messy.
First up, the standout window is this coming Monday morning (24 August) at Conchalio. We’re looking at a 2ft SSW groundswell, with a long 18-second period pushing moderate energy (418). The wind is glassy, coming light from the NNE, which is going to leave the surface smooth as a mirror. The water temp is about average for this time of year, so no surprises there. This is a beginner-friendly break, and with conditions this clean, it’s a perfect session for getting your feet wet.
The mornings are definitely the move here. Tuesday (25 August) and Wednesday (26 August) both start glassy with E and NE winds, keeping that 2-2ft SSW swell clean. The energy drops a bit into the weak-to-moderate zone (337 and 194), but for a small-wave board, it’s still fun. The afternoons turn cross-onshore and choppy, so plan to be out early.
Thursday morning (27 August) is glassy again with a 1ft swell, but the energy is a touch higher (230) thanks to a longer 18-second period. It’s tiny, but clean.
Now, here’s where it gets interesting. Friday (28 August) morning is a real highlight. The swell picks up to 3ft from the SSW, period drops to 16 seconds, but the energy jumps to 636 (moderate). The wind is a light cross-offshore from the NNE, making for clean, lined-up waves. This is a very good session.
Saturday (29 August) morning is the big one. Swell size jumps to 5ft from the SW, with 16-second period and a combined energy of 960 (strong). Winds are light cross-offshore from the north. This is the best of the first week – clean, solid, and punchy. It’s still manageable for most, but that size is getting into more interesting territory.
Sunday (30 August) morning keeps the 5ft SW swell going, but with glassy SSE winds. The energy is still strong (786). Another fantastic morning.
Looking into the second week, the pattern holds. Monday (31 August) and Tuesday (1 September) mornings have glassy conditions and smaller 3-4ft SSW swell. The energy is still moderate (570 and 373). Clean, but not as powerful.
Then we get to the real standout of the whole forecast. Friday (4 September) morning is a cracker. A 6ft SSW groundswell, with a 17-second period, pushes a massive energy reading of 1878 (very strong). The wind is a clean offshore from the NNE. This is excellent surf, but at 6ft, it’s getting too big for beginners. This is for the experienced crew.
Saturday (5 September) morning is just as good. Still 6ft from the SSW, 16-second period, with glassy calm winds. The energy is 1565. Again, expert territory, but absolutely pumping if you can handle it. The long period means these waves will have heaps of power and long waits between sets – perfect for a point break setup.
Sunday (6 September) and Monday (7 September) mornings stay good, with 4-5ft SSW swell and clean winds, but the energy starts to drop back down (841 and 717). The last day of the forecast, Tuesday (8 September) morning, is back to 3ft with glassy conditions and a 14-second period.
So, the bottom line: Saturday morning (29 August) and Friday morning (4 September) are your two best bets. Saturday is the best of the first week for a bigger crowd of intermediates, and Friday the 4th is the expert-level standout. The mornings are always the call here – the afternoons get blown out. Don't sleep on that Friday the 4th session.
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.
