The Lowdown

Alright folks, Rusty here with the skinny on what’s cooking at Conchalio.

We’ve got a solid run of cleaner, smaller surf kicking things off, with some real quality mornings on the cards. The water temp is sitting at a warm 87°, which is a touch warmer than normal for this time of year, so you might not even need the full spring suit. The opening days look like a classic early glass-off scenario.

Tuesday morning the 15th is all about perfection. It's small at 2ft from the SSW, but with a glassy surface and a super long 18-second period, those waves will have some real push for the size. The combined swell energy is moderate (547). A standout for a classic log or a mid-length.

Wednesday morning the 16th builds a touch, hitting 4ft from the SSW on a 16-second period, still with that morning glass. Swell energy is strong (922), making it the pick of the first few days for something with a bit more power.

Thursday the 17th and Friday the 18th keep the same theme: clean mornings with glassy winds and waist-to-chest high waves from the SSW and SW. Friday afternoon gets interesting—it drops back to 2ft but the period jumps to 20 seconds, which is a very long groundswell. That kind of period can make for some weirdly straight waves at a beach break unless the sandbanks are perfect, but if they are, it’ll be a rippable little wave.

Saturday the 19th and Sunday the 20th are a mixed bag. Clean mornings with small, long-period swell again, but the afternoons get blown out by a cross-onshore breeze. The Sunday morning session on the 20th is worth noting: 3ft, 19-second period, glassy. Another cracker.

Monday the 21st starts with a clean 4ft SW swell (18-second period), strong energy (823) but watch for afternoon thunderstorms kicking up a cross-shore breeze.

Then we get a bit of a lull from Tuesday the 22nd through to Friday the 25th. The swell drops, the period shortens, and we’re looking at small, weaker waves with a lot of wind and stormy afternoons. It’s not a write-off, but the quality dips noticeably.

Now, if you've got the skill and the nerve, mark your calendar for Saturday the 26th. That morning, a solid 8ft S swell with a short 10-second period hits with an offshore wind and glassy conditions. The combined energy is massive (1460). This is expert territory only—too big for beginners, and that short period will make for some thick, punchy walls. The wind holds offshore through the afternoon at 8ft, so it’s a full day for the experienced crew.

Sunday the 27th is a letdown—big leftover swell but cross-shore and onshore winds turn it into a mess. Monday the 28th is a complete loss with strong onshore winds and poor quality.

Looking way out, Tuesday the 29th morning sees a drop back to 4ft with a decent 12-second period and glassy conditions again. Then Wednesday the 30th has a clean 6ft morning building to a 7ft afternoon, both from the SSW, with glassy winds. That afternoon is a standout for the second week: clean, punchy head-high waves, but it's far enough out to be less certain.

So overall, the clear standouts are the Tuesday morning 15th for a long-period, glassy small-wave session, and the Saturday morning 26th for the big, punchy stuff for experts only.

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.
