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.

May at El Muro, Chile, offers consistent surf with an average swell height of 1.7m and a strong period of 13.7s, ensuring powerful, well-formed waves. The swell is predominantly from the SW (62.5% of waves in the 1-2.5m range), providing clean, long-period groundswells ideal for intermediate to advanced surfers. Wind conditions are less favorable, with only 14% of days offering ideal offshore winds (light ENE-E). The most common winds are onshore S-SSW (10-30kph), which can create choppy conditions, particularly in the afternoons. Smaller days (1-1.5m) are manageable for less experienced surfers, while larger days (1.5-2.5m) deliver more hollow, heavier waves. Morning sessions are best to avoid stronger winds. Overall, May delivers solid SW swells but requires patience for optimal wind conditions.
