The Lowdown

Alright, folks, Rusty here. Let’s have a look at what’s cookin’ for Playa-Conchalio over the next couple of weeks.

Straight up, the first week is a bit of a mixed bag—some real nice morning windows, but the afternoons get blown out. The real standout is way out there at the tail end of the window, around the 29th of August and into the 30th. That’s where the magic is.

For the first few days, we’re looking at a solid, consistent groundswell. Tuesday morning, the 18th, kicks off with a glassy 4 ft SW swell (14 second period) and a good amount of energy (526). The water temp is about average for this time of year, so no surprises there. The wind is off the land, glass, and the waves are clean. But by afternoon, the onshore kicks in and it’s junk. Same pattern repeats Wednesday and Thursday mornings: glassy conditions, clean little 3 ft to 2 ft SW swells, but the afternoons are a write-off. Friday the 21st is small and weak, not worth paddling out for.

We get a little bump on Saturday the 22nd morning—3 ft from the S, period drops to 11 seconds, but it’s glassy and clean. That’s a decent little session. Then Sunday the 23rd morning is another beauty: 3 ft SSW groundswell with a 14-second period and a massive 538 energy reading. Glassy, clean, and the crowd might be there, so keep your eyes open.

Then we hit a bit of a lull through the middle of the week. The 24th through the 27th are small, mostly under 2 ft, and the energy drops off. It’s surfable on the mornings but nothing to write home about.

Now, hold on to your board. The 28th morning shows signs of life with 3 ft SSW, 16-second period, and 484 energy. Glassy again. But the real prize is Saturday the 29th of August. The morning session is pumping: 5 ft SSW groundswell, 17-second period, 1163 energy—that’s serious juice. Glassy, offshore, and it’s calling for experienced surfers because at 5 ft, it’s getting a bit stout for beginners. The afternoon gets a little bump up to 5 ft, but the wind turns cross-onshore, so it’s not as clean. Sunday the 30th morning is nearly as good: 5 ft SSW, 15 seconds, 1105 energy, and glassy again. That’s a top-tier morning for the crew who know what they’re doing.

The swell hangs on into Monday the 31st morning—5 ft, 14 seconds, 789 energy, glassy—still a very good session. And even into Tuesday the 1st of September, we’ve got 4 ft SSW, 13 seconds, calm and glassy. It’s not the same power as the 29th, but it’s clean and fun.

The 2nd of September morning wraps it up with a nice 4 ft SSW, 12-second swell, 808 energy, and glassy conditions. A solid way to finish the run.

So, if you’ve got a free morning, aim for the 29th of August, the 30th, or the 31st. That’s the best of the lot. The rest of the time, it’s early bird gets the worm, because the afternoons are a mess.

Stay stoked,
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.
