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.

December at Martinhal delivers solid surf conditions with a consistent average swell height of 2.1m and a strong 12.4s period, ensuring powerful, well-spaced waves. The primary swell direction is from the WNW and NW, contributing to the majority of rideable waves (peaking between 1.5–2.5m), while SW and WSW swells also provide notable energy. Smaller but cleaner ENE/ESE swells occur occasionally, offering variety. Wind conditions are less favorable, with only 24% of days providing ideal offshore or light cross-shore winds (typically ENE to E). Stronger onshore winds from the W/NW sector are common, creating chop, though mornings often see lighter winds. Expect a mix of powerful, well-formed walls and occasional hollow sections, but patience is needed for optimal wind windows. Winter consistency is reliable, but wind management is key—early sessions or sheltered spots may yield the best rides. Intermediate to advanced surfers will find the most opportunity here, particularly on NW swells with lighter winds.
