The Lowdown
G’day, it’s Rusty here. Let’s cut to it. The next couple of weeks at Conchalio are going to be a treat, with the real magic happening in those first few hours of the day. The ocean is warm at 86°, so it’s all about boardies and a light rashie.
Starting with this coming Sunday morning, the 9th, we’ve got a solid 4ft of SSW swell rolling in on a 14-second period, with a strong energy of 578. The wind is just a whisper out of the NE, leaving it glassy as a lake. This is clean, pushy surf, and you’d be mad to miss it. The afternoon, though, the wind swings to the SSW and messes it up, so be out there early.
Monday the 10th morning sees the swell settle to a bit under 3ft from the SSW, still with that 13-second period and energy around 395. Light NE wind again, so you'll get some clean, fun waves. Tuesday the 11th morning follows the same pattern, with a similar 3ft of swell and 367 energy, and a glassy NNE wind.
Wednesday the 12th is a gem for the morning; the wind is absolutely dead calm, and there’s 3ft of long-period SSW groundswell at 16 seconds, with solid 501 energy. This is the sort of day that just feels easy, with the long period giving the waves a bit more shape and power than the size suggests. Thursday the 13th morning keeps the good vibes going with 2ft of groundswell and a glassy surface.
Now, get ready for the first standout. Friday the 14th morning shows a jump in energy to 799, with 4ft of SW swell on a juicy 18-second period. The ENE wind is just a slight air, leaving it clean. This is the first proper taste of the good stuff. But the real gem of the run is Saturday the 15th morning. We’re looking at 5ft of SW groundswell, energy peaking at a strong 948, and the wind is dead calm. It’s going to be big, clean, and relentless. This is the session you set your alarm for.
Sunday the 16th morning still holds up with 4ft of SW swell, a 15-second period, and 721 energy, with a light N wind keeping it glassy. The daily pattern through the rest of the first week keeps pumping out clean, smaller surf in the mornings, with Monday and Tuesday offering up around 3ft to 3ft of clean swell.
The second week, things get a bit more varied. Thursday the 20th morning brings a change, with 4ft of S swell, but the period drops to 10 seconds and energy is at 552. The W wind is dead calm, so it’ll be glassy, but that shorter period will make it a bit more closed out and not as clean-lined. The swell backs off again after that.
But then, on Sunday the 23rd morning, there’s a late pulse. 3ft from the SSW on a long 19-second period, and the energy is right back up to 766. The SSE wind is light, so it should be pretty clean. This long-period swell is one for the points and reefs – it could be a proper treat if it lines up. The Monday the 24th after that offers up a smaller, but still clean, 3ft from the SSW on an 18-second period, with good energy at 515, and the wind stays light in the morning.
So, the bottom line: be a morning person. The afternoons are almost all victims of onshore wind, so you have to beat the clock. The two big standouts are Saturday the 15th and Friday the 14th; those are your top-tier sessions. The long-period swells later in the second week, on the 23rd and 24th, are promising too but not something to bank on just yet.
Conchalio is a fairly consistent break, so you’re never waiting around too long. It’s a friendly wave for beginners, but when it's pushing towards 4ft plus, give it a bit more respect. You might find a few people out on those clean mornings, but it shouldn't be too crowded.
Get amongst it, this is a solid forecast.
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.
