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.

October at Barra de Potosi offers solid surf conditions, with an average swell height of 1.4m and a consistent period of 14.6s, ensuring well-formed and powerful waves. The dominant swell direction is primarily from the SSW and SW, contributing to 61% of waves in the 1-2m range, while larger sets (2m+) appear around 4% of the time. Wind conditions are favorable 45% of the time, with light to moderate breezes typically coming from the N to ENE in the mornings, often turning onshore (SSW-WSW) by midday. However, stronger winds (>20kph) are rare, occurring only 14% of the time. The combination of decent swell energy and manageable winds makes this a reliable month for intermediate to advanced surfers, with peak sessions likely during morning hours when winds are lightest. Expect some variability, but overall, October delivers consistent surf with good shape and minimal wind disruption.
