The Lowdown
Alright, grab your board and let's get into it. Rusty here.
We've got one spot on the radar for the next couple of weeks: Conchalio. It's looking like a classic setup for this place, with a decent pulse of swell arriving right away. The water temp is sitting at 86°, which is about 2° warmer than usual for this time of year, so it's noticeably balmy.
The action kicks off this Saturday morning, September 5th. We're looking at a solid 6 ft swell from the SSW, with a long 16-second period. That's proper groundswell energy, and with 1390 units of combined energy (moderate wave energy), it's got some real punch. The wind is dead calm, glassy conditions, so the surface will be like a mirror. This is the standout of the whole forecast. The swell direction is a touch south of the ideal W, but the size, period, and wind combo make it a no-brainer. Be aware, though, at 6 ft, this is getting a bit chunky for beginners, and the long period will mean it's better for the points and reefs than the beach breaks. Crowds are sometimes an issue here, so get in early.
Saturday afternoon sees the wind shift cross-on and pick up to 15 km/h (9 mph), turning it choppy and messy. Not worth it.
Sunday morning, September 6th, the swell drops a little to 5 ft with a 15-second period, but the wind is cross-shore and light. It’s surfable but nothing special. The energy drops to 942, still moderate.
Monday morning, September 7th, is another good call. The swell is down to 4 ft, but it’s still a clean 14-second period from the SSW, and the wind is glassy again. This is a much more manageable size for most surfers.
After that, the surf trends down through the middle of the week. Tuesday morning the 8th and Wednesday morning the 9th have small, clean waves in the 3 ft to 3 ft range with long periods, but the energy is dropping fast (down to 440). They're fun, small waves.
We get a little bump on Thursday morning, September 10th. A 3 ft, 17-second period SSW swell rolls in, combined energy jumps back to 930, and it’s glassy. That’s a nice surprise and another top pick for the clean conditions.
Friday morning the 11th is similar: 4 ft, 16-second SSW, glassy. Another solid morning session.
After that, the swell fades out slowly over the weekend and into the following week. There's a gap from about the 13th onwards where it gets really small, 2 ft to 3 ft, but the conditions remain mostly glassy in the mornings. There's a tiny spike of longer-period energy on the 14th (19 seconds!) and 15th, but it's only 2 ft to 3 ft.
Looking further out, the mornings of the 16th and 19th of September show some promise. The 16th has a 4 ft, 16-second SSW swell with glassy NE wind. The 19th has a 2 ft, 19-second SSW swell with clean cross-offshore wind. These are long-range whispers, so don't bank on them, but they're worth watching.
To wrap it up, Saturday morning the 5th is the absolute best of the bunch – big, clean, and powerful. Thursday the 10th and Friday the 11th mornings are your next best bets for clean, fun waves. The rest is a slow fade into small, clean morning waves.
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.
