El Muro - surf spot statistics

El Muro in Chile is a consistent surf spot with reliable ground swells year-round, rarely experiencing flat conditions. The swell is predominantly ground swell, accounting for 88-96% of the time, with minimal wind swell interference. Mean swell heights range between 1.5m to 1.8m, peaking from May to August, offering slightly larger and more powerful waves during these months. However, wind conditions are challenging, with bad (onshore or unfavorable) winds dominating 83-95% of the time. The best wind windows appear from May to July, when good wind probabilities rise to 14-17%, though still low overall. Given these factors, the optimal months for surfing El Muro are May through July, when swell size is marginally bigger, and wind conditions, while still often poor, have slightly higher chances of being rideable. Early mornings or protected sections may help mitigate wind issues. Outside this window, swells remain steady but wind conditions worsen, making clean surf sessions rare. Advanced surfers comfortable with stronger winds and consistent ground swell will find the spot surfable year-round, but mid-winter offers the best compromise between swell energy and occasional favorable winds.

April at El Muro, Chile, offers consistent surf with an average swell height of 1.6m and a solid 14.1s period, indicating powerful, well-spaced waves. The swell is predominantly from the SW (64.9% of waves between 1-2.5m), with WSW and W also contributing to clean, surfable conditions. Smaller SW swells (0.5-1m) occur occasionally, but the majority are in the 1.5-2m range, ideal for intermediate to advanced surfers. Wind conditions are less favorable, with only 10% of days providing ideal offshore winds. The dominant winds are from the SSW and SW (blowing 10-30kph 34% of the time), which can create choppy onshore conditions. However, lighter winds (0-10kph) from the S and SW appear in 8-15% of cases, offering cleaner sessions. Overall, expect punchy, powerful waves with good shape when winds cooperate, but be prepared for occasional wind-affected surf. The long-period SW swell ensures quality energy, making it a reliable spot in April for those comfortable with overhead conditions.
