Barra de Potosi - surf spot statistics

Barra de Potosi, Mexico, offers consistent year-round surf conditions with ground swells dominating the swell regime almost exclusively. The swell is nearly always present, with ground swell percentages ranging from 90% to 100% across all months, ensuring reliable wave energy. The mean swell size varies from 0.9m in the winter months (December-January) to a peak of 1.6m in September, suggesting slightly larger and more powerful waves as the year progresses toward the late summer and early fall. Wind conditions are the primary limiting factor, with unfavorable winds occurring more frequently (49-68%) than favorable winds throughout the year. The best balance between swell size and wind conditions occurs from June to September, when the swell remains solid (1.5-1.6m) and the likelihood of good winds improves slightly, peaking in September at 51%. While the waves are rideable year-round due to the high ground swell consistency, late summer and early fall (June-September) present the most favorable combination of swell size and marginally better wind odds, making this period the optimal window for surfers seeking dependable conditions. Winter months offer smaller, more manageable waves but come with higher chances of onshore winds.

April at Barra de Potosi offers consistent surf conditions with a focus on mid-period swells and variable wind patterns. The average swell height is 1.3m with a solid 15s period, indicating well-organized and rideable waves. The dominant swell directions are SSW (61.53% of waves in the 1-1.5m range) and SW (8.66% in the same range), providing favorable energy for the spot. Larger swells (1.5-2m) from the SSW occur 13.54% of the time, offering punchier sections for advanced surfers. Wind conditions are a mix, with only 32% of days providing ideal offshore or light cross-shore winds—typically from the NE to ENE (17.26% combined in the 0-20kph range). However, moderate onshore SW and WSW winds (up to 20-30kph) are present 10.89% of the time, which can degrade wave quality. Overall, April delivers reliable surf with peak conditions when swell aligns with lighter NE winds, though surfers should monitor wind shifts closely for optimal sessions.
