The Lowdown
Alright, Rusty here. We got a proper run of surf shaping up at Conchalio, but you gotta pick your moments. Water temp is 87°F, more than a degree and a half warmer than usual for this time of year - feels like a warm bath, so leave the rubber at home.
First waves show Thursday morning, August 27th. Small - 1ft of SSW groundswell, 18-second period, glassy as a mirror with a light NNE breeze. Wave energy is moderate at 230. It’s clean fun for the beginners. Afternoon gets choppy with a cross-on wind, so early is the call.
Friday the 28th looks better. Morning glass again, 3ft SSW swell, 16 seconds, and the energy jumps to strong at 636. That’s long-period groundswell for a beach break, so expect some nice walls but longer lulls. Crowds are ‘sometimes’ here, you might see a few heads.
Now the standout. Saturday morning, August 29th. That’s your session. 5ft of SW swell, 16 seconds, glass off, and energy is very strong at 1083. For experienced surfers, this is excellent. It’s pushing the beginner limit, but anyone with skills is in for a treat. The afternoon hits 5ft and gets onshore, so get out early.
Sunday the 30th is still pumping - 5ft SW, 14 seconds, glassy morning, energy down to 895 but still very strong. Another great dawn patrol.
Monday the 31st: 4ft SW, 13-second period, glassy with no wind. Energy moderate at 561. Clean and fun, but backing off. Tuesday September 1st keeps it going: 3ft SSW, glassy morning, period dropping to 13 seconds.
Wednesday September 2nd, the wind turns cross-offshore from the ESE - that’s clean faces all day. 3ft SSW, 13 seconds, energy at 551.
Then a quiet spell Thursday the 3rd with thunderstorms and cross-on wind, swell dropping to 3ft. Not much going on.
But hold on - Friday morning, September 4th, a new pulse hits. 4ft SSW, 17-second period, glassy, energy very strong at 1114. That’s proper groundswell. Saturday September 5th morning is the big one: 6ft SSW, 16 seconds, energy at 1619. That’s expert territory - over 5ft, so beginners stay on the beach. Afternoon gets risky with storms and cross-on wind.
The second week settles down with morning glass on Sunday 6th (4ft), Monday 7th (4ft), Tuesday 8th (3ft) - all clean, all good for intermediate surfers.
One more flare: Thursday morning, September 10th, 5ft SSW, 16 seconds, glassy, energy at 1054. Excellent for experienced surfers again.
Bottom line: your best bets are Saturday August 29th morning, and the big Friday 4th and Saturday 5th September mornings. Get the early ones.

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.
