The Lowdown
Alright folks, Rusty here. Let's take a look at what's coming up.
The first real chance to get wet is Saturday morning, August 15th. We've got a nice 5ft SW groundswell rolling in with a very long 16-second period, packing a solid punch (moderate energy at 1074). The wind is glassy out of the NNE at just 3 mph, so the water will be like a mirror. Water temp is right around 86°, which is normal for this time of year. This is a standout for the experienced crew, as that long-period groundswell can be a bit of a challenge at the beach but will line up nicely at the right spots. The main break is Conchalio, a fairly consistent spot that's usually good for beginners, but with this size and period, it's definitely more for the advanced surfers.
Sunday the 16th still has some 4ft SW swell hanging around, but the magic is gone. The morning is clean with a light cross-offshore breeze, but it's not the same. The following week sees the swell drop off and the quality goes downhill fast. There's a big gap of average to poor conditions from Monday the 17th through Friday the 21st, with the swell bottoming out around 2ft and losing its period. The wind gets messy in the afternoons too.
Things get interesting again on Friday morning, August 28th. We get a late-season pulse: 3ft SW groundswell, 16-second period, glassy conditions, and a solid energy reading (791). It's a promising long-range standout, but it's a long way out, so don't book the trip just yet. The following weekend, the 30th, also looks tidy with a 4ft SSW swell and clean offshore winds, but the 15th is still the main event.
So, the bottom line: Saturday the 15th is your day. After that, keep your eyes on the end of the month for another shot of clean, long-period groundswell.
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.
