The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s comin’ down the line for Conchalio. We’ve got a solid run of surf ahead, but it’s a game of two halves: the first week offers smaller, cleaner waves for the learner crew, while the second week packs a punch for the experienced surfers.
The first proper surf kicks off Saturday morning, August 22. The water temp is about average for this time of year, so you won’t be needing a thick steamer. Saturday morning, it’s glassy calm with a clean 3 ft swell from the south, period at 11 seconds. The energy’s moderate (319). It’s a sweet little window for the beginner crew. The afternoon goes onshore and messy, so hit it early.
Sunday the 23rd and Monday the 24th keep the same vibe: small but clean. Sunday morning with the NE breeze is glassy, 3 ft from the SSW at 14 seconds (380 energy). Monday is even better, 2 ft from the same direction but with a very long period of 18 seconds (418 energy). That long period will make the waves line up a bit more shapely, but it might break a little too straight at the beach here. Still, clean as a whistle.
Tuesday the 25th through Thursday the 27th are a bit quieter, with swell dropping to 1 ft–2 ft. The wind stays light and mostly cross-off to glassy, so you’ll still find a ripple if you’re desperate. Energy drops to around 110–230, so it’s weak. Not worth burning the petrol for.
Now, Friday the 28th is where things start to get interesting. The morning is glassy again, but the swell jumps to 2 ft from the SW with a groundswell period of 20 seconds (792 energy). That’s a lot of energy for the size – those sets will be clean and powerful. The standout for the first week is Saturday the 29th. Morning glassy conditions, swell bumping up to 5 ft from the SW at 16 seconds, and energy cranking to 1107. That’s strong wave energy. It’s going to be too big for beginners and is a proper expert-only session. The wind is off, the waves are clean – that’s your top pick.
Sunday the 30th and Monday the 31st keep the morning glassy, with 5 ft and 4 ft swell respectively, but the afternoons get blown out. The Tuesday morning, September 1, is calm again with 3 ft, but the risk of thunderstorms later on spoils it.
The second week gets even better. Wednesday September 2 looks a bit iffy, but Thursday morning September 3 is clean with 3 ft from the SSW at 17 seconds (681 energy). Then Friday September 4 is the absolute standout of the whole run. Morning sees 4 ft from the SSW at 17 seconds (1199 energy) – strong – and the wind is light cross-off, so clean. The afternoon? Glassy, 5 ft from the SW at 17 seconds, energy at 1330. That’s a five-star session for experienced surfers only. Saturday September 5 morning is also clean with 5 ft at 16 seconds (1168 energy). Sunday the 6th rounds it out with a glassy 4 ft, 15 seconds.
Crowds are a possibility at Conchalio, especially on those clean weekend mornings. It’s a fairly consistent spot, so when it’s good, people will be there. Get there early if you want a park.
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.
