The Lowdown
Alright, this is Rusty coming at you from the shores of Playa-Conchalio.
Looking at the next couple of weeks, we’ve got a solid run of surf on the cards here. The water is sitting at a warm 86°, which is a touch above average for this time of year, so you can leave the thick rubber at home. The pattern starts a bit slow but builds into a really nice pulse of swell, especially towards the end of the first week and into the second.
Let’s kick things off on Tuesday the 1st. The morning session is looking good with some clean 3ft swell out of the southwest, a long 13-second period giving it some proper push. The wind is glassy, just a slight air from the southeast, so the surface will be clean. The combined energy is sitting at a solid moderate level (428), so there’s plenty of push for a beginner-friendly wave. The afternoon goes a bit wonky though with a cross-shore wind, so get out early.
Wednesday the 2nd starts with a bit of cloud and a light onshore wind, but the swell sticks around at 3ft with a similar period. It’s not a total write-off, but not the pick of the week either. The afternoon has a risk of storms and a cross-on breeze, so I’d give that a miss.
Now, Thursday the 3rd is where it starts to get exciting. Morning glass-off conditions with a northwest breeze, and we’ve got 3ft swell building. By the afternoon, it’s pushing 4ft from the southwest with a long 15-second period. The energy jumps up to 736, and the winds go glassy again. This is a proper window of clean, fun waves.
Friday the 4th is a standout. The morning brings 5ft swell from the southwest with a long 17-second period and absolutely no wind. It’s glassy, clean, and the energy is cranking at 1366. This is getting into proper territory – solid, powerful waves for experienced surfers. The afternoon gets a bit tricky with a cross-on breeze and the swell building to 5ft, but the morning is the real deal.
Saturday the 5th morning is another cracker. Completely calm winds, glassy conditions, and 6ft of southwest swell. That’s getting up there, so if you’re not comfortable in overhead surf, maybe sit this one out. The energy is very strong at 1390. The afternoon has an onshore breeze so it won’t be as clean.
Sunday the 6th morning still has decent 5ft swell with glassy conditions. The energy is dropping a bit (952), but it’s still a good session. The afternoons start to get a bit messy with onshore winds through the rest of the first week.
Moving into the second week, the pattern holds. Monday the 7th morning is clean with 4ft swell, and Tuesday the 8th has another glass-off with 3ft. The best of the second week looks like Thursday the 10th morning – glassy, calm winds, and 3ft of long-period 17-second swell. The energy is strong at 930. Friday the 11th morning is also a good shout with similar conditions. Later in the week, Saturday the 12th and Sunday the 13th mornings still offer clean 3ft to 3ft waves, but the energy is dropping off.
Right at the tail end, Tuesday the 15th morning and Wednesday the 16th morning both have clean glassy conditions with 2ft to 3ft swell and long periods. The energy is moderate, but the conditions will be perfect for a longboard or a funboard session.
So to sum it up, the absolute best windows are Friday the 4th and Saturday the 5th mornings for the biggest, cleanest swell. Thursday the 10th morning is the pick of the second week. This break is fairly consistent, so even the smaller days offer something rideable. The crowd factor is worth noting – it can get busy here sometimes, so get in early for the peak sessions.
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.
