La Bocana - surf spot statistics

La Bocana in El Salvador offers consistent year-round surf conditions, with ground swell dominating nearly every month, rarely dropping below 92% prevalence. The smallest swell size averages around 0.9m in January, gradually increasing to peak at 1.5m in September before tapering off again by December. Wind conditions are less favorable, with "bad" winds (onshore or cross-shore) outweighing good offshore winds in every month, averaging between 51-61% unfavorable winds. The best balance between swell size and wind conditions occurs from November to February, when winds are slightly more manageable (45-49% good days) and swells remain in the 0.9-1.1m range—ideal for intermediate surfers. The largest swells arrive from May to September (1.4-1.5m), but the higher proportion of poor wind conditions (60%) makes sessions more hit-or-miss. March and April also see decent swell (1.1-1.2m) with wind stats similar to winter, offering an underrated window. July stands out as the only month with a marginal no-swell probability (1%), though this is negligible. For advanced surfers chasing size, September delivers the biggest waves (1.5m), but patience with wind will be required. Beginners may prefer December or January, when smaller waves and slightly improved wind odds (47-45% good days) allow for more controlled sessions. Ultimately, La Bocana’s consistency in ground swell makes it a reliable spot year-round, but the trade-off is persistent wind challenges, requiring surfers to time sessions carefully.

September at La Bocana delivers consistent surf with an average swell height of 1.5m and a solid 14.3s period, ensuring powerful, well-spaced waves. The most dominant swell directions are SSW (49.9% in the 1-1.5m range) and S (8.17% in the same range), with larger sets reaching 2-2.5m from SSW (4.24%) and WSW (0.45%). While most waves are in the 1-2.5m range, there’s a tendency for SSW swells to produce overhead conditions (27.13% at 1.5-2m). Wind conditions are favorable 40% of the time, with the majority of winds blowing light to moderate (10-20kph) from the S to SSW (5.14% and 4.63% frequency, respectively). However, stronger winds (20-30kph) occasionally come from the W and WSW, which may create bumpy conditions. Overall, September offers solid, clean surf with a mix of mid-sized and bigger waves, best suited for experienced surfers when the SSW swells and lighter winds align.
