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.

October at Martinhal offers decent surf conditions with an average swell height of 1.5m and a solid period of 11.3s, ensuring well-formed, powerful waves. The swell direction is predominantly from the NW and WNW (making up over 40% of the swell distribution in the 1-2.5m range), which aligns well with the beach's orientation, producing consistent, rideable waves. WSW and SW swells also contribute, adding variety to the lineup. Wind conditions are favorable for surfing 34% of the time, with the most common ideal scenario being light offshore or cross-offshore winds from the E to NE quadrant (below 20kph). However, stronger W to NW winds (20-30kph) occur frequently, which can create choppy conditions—especially when combined with larger W/NW swells. Overall, October delivers a mix of clean sessions and challenging days, best suited for intermediate to advanced surfers who can handle varying wind and swell combinations.
