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.

June at El Muro, Chile, offers solid surf conditions with a dominant SW swell direction, contributing to the majority of waves in the 1–2.5m range (over 70% of the time). The average swell height is 1.7m with a strong 13.5s period, providing consistent, well-formed waves ideal for intermediate to advanced surfers. The most frequent swell range is 1.5–2m (25% SW, 8.8% WSW), ensuring powerful, clean rides when combined with the long period. Wind conditions are less favorable, with only 15% of days offering ideal offshore or light winds, mainly from the N to ENE sectors. However, SSW and SW winds—often onshore—prevail, creating choppier conditions (SSW winds at 10–20kph occur nearly 14% of the time). For the best sessions, target days when winds shift northerly or easterly, leveraging the dominant SW swell for hollow, well-organized waves. Despite occasional wind challenges, June delivers dependable swell energy for strong surfers.
