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 March, Martinhal offers decent surf conditions with an average swell height of 1.8m and a solid period of 12.1s, ensuring well-formed waves. The dominant swell directions are WNW and NW, contributing to the majority of rideable waves, particularly in the 1-2.5m range, which is ideal for intermediate to advanced surfers. These swells are clean and powerful, often holding up well at this exposed spot. Wind conditions are a mixed bag—only 27% of the time are they truly favorable (light offshore or sideshore), but when they align, the waves can be excellent. The most problematic winds come from the north and northeast, which can create choppy or cross-shore conditions. SE and ESE swells are less frequent but can produce fun, albeit smaller, waves. Overall, March delivers consistent surf with good size and quality, though wind variability means timing sessions for optimal conditions is key. Experienced surfers will find plenty of opportunities, especially on WNW/NW swells with lighter winds.
