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 June, Petacalco offers consistent surf conditions with an average swell height of 1.6m and a strong period of 14.7s, indicating powerful, well-spaced waves. The primary swell directions are SSW (67.2% of waves between 1-2.5m) and S (13.3% in the same range), delivering clean, rideable waves with good energy. SW and SSE swells contribute smaller but still surfable waves. Wind conditions are favorable 39% of the time, with lighter winds (0-20kph) predominantly from the ENE to ESE, ideal for glassy or offshore conditions in the morning. However, stronger onshore winds (SSW-WSW at 20-30kph) can occasionally create choppier surfaces. Overall, June is a reliable month for intermediate to advanced surfers, with consistent SSW swells and morning offshore winds providing the best sessions. Size and power peak in the 1.5-2.5m range, making it suitable for high-performance surfing when winds align.
