Murtosa - surf spot statistics

Murtosa, Portugal, is a surf spot that benefits primarily from ground swells, particularly during the winter months, making it ideal for experienced surfers seeking powerful, clean waves. The best conditions occur from **October to March**, when ground swell dominance is highest (64-91%), and mean swell sizes range from **1.9m to 2.5m**, providing consistent and sizable waves. December stands out with **86% ground swells**, **2.4m average swell size**, and the highest likelihood of good wind conditions at **34%**. January and February are also excellent, with similarly strong ground swell percentages (89-91%) and swell heights around **2.4-2.5m**, though offshore winds are still somewhat unreliable (good wind conditions only **32%** of the time). November offers a good balance with **75% ground swells** and **2.2m waves**, while October marks the start of the peak season with improving swell quality. From **April onwards**, the conditions deteriorate as wind swells become more prevalent, and swell size drops below **2m**, with **May to August** being the least favorable due to weak swell energy, higher wind swell influence, and poor wind consistency (only **15-20% good wind days**). September is a transitional month, showing slight improvement with **45% ground swells** and **1.5m waves**, though it’s not yet at winter levels. Overall, serious surfers should target **late autumn through early spring** for the biggest, cleanest waves, accepting that wind conditions can still be challenging, while summer months are best left to beginners or those comfortable with smaller, wind-affected surf.

October in Murtosa offers solid surf conditions with a mean swell height of 1.9m and a healthy period of 11.3s, indicating well-organized and powerful waves. The dominant swell directions are W and WNW, contributing most of the rideable waves, especially in the 1.5-2.5m range, which peaks around WNW with 14.8% in the 1.5-2m category.

Experienced surfers will find plenty of opportunities, particularly on WNW swells.
