The Lowdown
Alright folks, Rusty here. Let’s take a look at what’s coming up for our local stretch.
We’ve got a bit of a slow start to the forecast period, but once the swell gets its act together, this place is going to fire. The first few days are offering small, rideable waves, with the real magic starting next week. The water temp is sitting right around 86°, which is about average for this time of year, so no surprises there.
The first real standout is Monday the 20th of July. Conchalio is looking clean and glassy in the morning, with a 3ft SSW swell pushing in at a solid 16 seconds. That’s a nice groundswell, and with the glassy conditions, it’s going to be a super fun session for all levels. The combined energy is 557 (moderate), so there’s enough push to get into some nice waves. Crows are sometimes an issue here, so be ready for a few others in the water.
Now, hold onto your leashes, because the real pulse arrives on Friday the 24th of July. The morning session is going to be epic. We’re looking at a 3ft SSW swell, but the period is a massive 24 seconds – that’s a very long period groundswell, and it’s going to unload with a lot of energy (1128 in the combined energy reading). This is expert territory, as the power will be serious. The wind is completely calm, making it dead glassy. For experienced surfers, this is the session of the fortnight. Just be aware, with that kind of period, the waves will want to run straight at a beach break, but Conchalio is an exposed beach, so pick your peak carefully.
The energy just keeps building. Saturday the 25th and Sunday the 26th of July are both seeing excellent conditions for experienced surfers, with glassy mornings and swell heights climbing to 4ft, with periods still in the 18-21 second range (combined energy over 1000). This is a solid run of surf.
The biggest swell of the forecast hits on Monday the 27th and Tuesday the 28th of July. We’re talking 5ft SSW swell with periods of 17-19 seconds. The combined energy readings are massive – 1765 and 1860. This is a big, powerful swell. Monday morning is glassy and perfect for experts, while Tuesday morning has offshore winds keeping it clean. The sheer size and power here mean it’s a day for the experienced crew only.
The swell starts to ease back towards the end of the month, but there are still some fun, clean windows. The 30th of July morning has a glassy 4ft SW swell, and the 31st of July morning offers clean 3ft waves.
The bottom line: The early part of the week is a slow build, but the real standout is the morning of Friday the 24th of July for that epic, long-period groundswell. The entire run from the 24th through the 28th of July is a serious swell event, with the 27th and 28th offering the biggest waves for experts only. Don’t sleep on the glassy mornings of the 20th and 21st for a cleaner, more manageable 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.
