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.

December at Barra de Potosi offers decent surf conditions with a mix of rideable swells and variable winds. The average swell height is 0.9m, paired with a solid 14.3s period, indicating well-spaced, clean waves with good energy. Most swells come from the SSW (41.62% in the 0.5-1m range, 19.77% in 1-1.5m) and SW (20.68% in 0.5-1m), providing consistent, workable waves, though they rarely exceed 1.5m. Wind conditions are favorable for surfing 44% of the time, with the dominant winds coming from the NNE to NE (light to moderate, 0-20kph) and occasionally from the SW (6.53% in 10-20kph). Offshore or light cross-shore winds are likely during these windows, keeping the surface clean. However, stronger NE or ENE winds (5-20+ kph) can create chop. Overall, expect small to mid-sized, well-formed waves with periods of good shape, especially when winds align. Advanced surfers may find occasional punchier sets, while intermediates will enjoy the majority of days with manageable conditions.
