Martinhal - surf spot statistics

Martinhal, Portugal, benefits from consistent ground swell throughout the year, with the best conditions for surfers typically occurring from late autumn through early spring. The highest-quality surfing months are December, January, and February, when ground swell dominates (82-90% of the time), and mean swell sizes reach their peak (2.0-2.1m). These months offer powerful, clean waves but come with challenging wind conditions—good winds occur only 24-27% of the time, meaning surfers will frequently deal with onshore or cross-shore winds. March and November still provide solid surf, with ground swell presence at 73-80% and mean sizes around 1.8m, though wind conditions remain similarly unfavorable. Spring (April) and autumn (October) see a transition, with ground swell decreasing to 63-64% and mean sizes dropping to 1.5-1.6m. Wind conditions improve slightly, but good winds remain below 35%. Summer (May-September) is the least consistent period, dominated by wind swell (50-82%) and smaller waves (1.0-1.3m). While offshore winds are more frequent (33-39%), the swell quality is significantly weaker, making it better suited for beginners or longboarders. Overall, advanced surfers will find the best waves from December to February despite the wind challenges, while intermediate surfers may prefer the shoulder months (March, November) for a balance of swell size and slightly more manageable conditions. Summer offers smaller, choppier waves but better wind reliability for casual surfing.

In February, Martinhal typically delivers solid surf conditions with an average swell height of 2.0m and a favorable period of 12.7s, indicating powerful, well-spaced waves. The dominant swell directions are WNW and NW, contributing to consistent, quality waves, particularly in the 1.5-2.5m range. These swells produce powerful, well-formed waves suited for experienced surfers, though the size and direction variability can also accommodate intermediate riders. Wind conditions are less reliable, with only 27% of days offering ideal offshore or light cross-shore winds (typically from the east or northeast). However, strong onshore winds (WSW-WNW) are frequent, which can create choppy conditions, especially when paired with larger swells. The spot handles larger swells well, but wind direction is critical for clean faces. Overall, February brings decent to good surf at Martinhal, with the best sessions occurring when winds align favorably with the dominant WNW/NW swell energy.
