The Lowdown
Alright folks, it’s Rusty here. Let’s look ahead at what we’ve got cooking at Conchalio. There’s no surf to start, but the waiting game will be worth it for a few proper clean sessions.
The first waves worth paddling out for show up on Thursday morning, 27 August. There’s a glassy, clean 1 ft SSW groundswell pushing through, and it’s packing a surprisingly solid 18-second period. The combined wave energy is moderate (230). That long period means better-shaped waves, but on a beach break it’ll want to stand up and close out a bit fast – still, it’s small enough to have fun on and super clean. Keep an eye on it.
Friday morning, 28 August, things step up. Glassy conditions again, with a cleaner 3 ft SSW swell, period around 16 seconds, and combined energy jumping to moderate (636). This is a lovely, clean morning session for the intermediate crew. Not a standout, but a solid start.
The real standout of this whole 16-day window is Saturday morning, 29 August. We’re looking at a clean, glassy 5 ft SW swell, a long 16-second period, and strong total wave energy (1090). This is excellent for experienced surfers – the size is getting up there (over 5 ft), so beginners should sit this one out. With optimal W direction in the mix and glassy offshore NNE wind, it’s about as good as it gets here for this stretch. Crowds are sometimes around, so it might be worth paddling out early.
Monday morning, 31 August, offers another clean, glassy 4 ft SW swell, moderate energy (445), and 13-second period. It’s a more relaxed, smaller option for the start of the week, well worth a look between work shifts.
Heading into the first week of September, we get another absolute standout on Friday morning, 4 September. A glassy 5 ft SW swell, long 17-second period, and very strong total wave energy (1487). This is excellent, expert-level stuff. The same applies to Saturday morning, 5 September: a glassy 6 ft SSW swell (over 8 ft, experts only), 16-second period, and huge combined energy (1471). These two days are the best in the whole run – big, clean, powerful groundswell.
Later, on Monday morning, 7 September, there’s a clean 4 ft SW swell with moderate energy (550) and a nice 14-second period, mixing in some cross-off wind which should keep the face tidy.
Finally, the last standout to pencil in is Wednesday morning, 10 September. A glassy 4 ft SSW swell, 16-second period, and extremely strong total wave energy (1631). That’s the highest energy reading in the whole outlook, and with zero wind, it will be perfect for experienced surfers.
Water temperature is not given as a specific number, but the anomaly is not flagged so it's about average for the time of year at Conchalio.
That’s the picture. Hold out for those glassy mornings. The second half of the window is where the real muscle shows up.
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.
