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.

November at Barra de Potosi offers generally favorable surfing conditions, with a mix of rideable swells and manageable winds. The average swell height is 1.1m, supported by a strong 14.5s period, ensuring consistent, well-spaced waves with good energy. The dominant swell directions are from the SSW and SW, accounting for the majority of waves in the 0.5-1.5m range (over 70% of the time), occasionally reaching 2m+. This south to southwest angle aligns well with the beach, producing clean, peeling waves when conditions align. Wind is favorable for surfing 43% of the time, with lighter breezes (10-20kph) most common from the NE to SW. Stronger winds (20-30kph) occasionally occur but are less frequent. Offshore or light cross-shore winds from the NE quadrant provide the best surface conditions, while stronger SSW or SW winds can create chop. Expect a reliable mix of waist-to-head-high waves, with some larger sets on swell pulses, making it a solid month for intermediate to advanced surfers. The key will be timing sessions around wind shifts and swell consistency.
