Petacalco - surf spot statistics

Petacalco, Mexico, offers consistent surf conditions year-round with a strong dominance of ground swell, making it a reliable destination for surfers. The best months for surfing here are typically from March to May and November to December, when swell consistency, size, and favorable winds align. March, April, and November stand out with 100% ground swell presence, mean swell sizes ranging from 1.2m to 1.3m, and good wind conditions over 55% of the time. These months provide clean, well-sized waves with minimal wind interference. May also offers solid swell (1.5m) though wind conditions are slightly less favorable. The winter months (December-February) have smaller but still consistent waves (1.0m-1.1m) with decent wind conditions around 50%. The summer months (June-September) see larger swells (1.6m-1.7m) but suffer from more frequent onshore winds, reducing rideable days. October marks a transitional period with improving winds and decent swell (1.5m). Overall, Petacalco is a year-round surf spot, with peak conditions in spring (March-May) and late autumn (November-December) when swell quality, size, and wind conditions combine optimally. Advanced surfers may still find good sessions in summer, especially early mornings before winds pick up.

In July, Petacalco offers decent surfing conditions with an average swell height of 1.6m and a solid 14.3s period, indicating well-spaced, powerful waves. The swell is predominantly from the SSW (around 61% of waves in the 1-2.5m range), delivering consistent, surfable energy. However, wind conditions are a mixed bag—only 41% of the time are they ideal for surfing, with light to moderate breezes from the NNE to ENE being the most favorable. Stronger winds from the SW to WSW can occasionally create chop, but the swell quality and size make it worthwhile for experienced surfers. Expect the best sessions when winds are light offshore or sideshore, complementing the SSW swell direction for clean, ridable waves.
