Foz do Lizandro - surf spot statistics

Foz do Lizandro in Portugal offers relatively consistent surf conditions year-round, with the best months for surfers typically falling between late autumn and early spring when ground swells dominate and wave heights are more favorable. From November through February, the spot sees the highest percentage of ground swells (74% to 91%) and the largest mean swell sizes (2.0m to 2.2m), providing powerful, clean waves ideal for experienced surfers. December and January stand out as prime months with the highest ground swell frequency, largest waves, and marginally better wind conditions (33% good winds compared to lower percentages in other months). However, wind conditions throughout this period remain challenging, with a high likelihood of onshore or cross-shore winds (67% to 74% bad wind days). Spring (March to May) and autumn (September to October) offer intermediate conditions, with some ground swell influence but smaller waves (1.7m to 2.0m) and worsening wind reliability. Summer (June to August) is the least favorable, dominated by wind swells (73% to 83%) and small wave heights (1.1m to 1.2m), making it more suitable for beginners or longboarders when the rare clean day occurs. Advanced surfers should prioritize the winter months despite the tricky winds, while those seeking milder conditions may prefer late September to October or March to April when swell consistency and size are still reasonable. The spot’s exposure to North Atlantic swells ensures year-round surfability, but patience and flexibility are key given the frequent suboptimal winds.

December at Foz do Lizandro delivers consistent surf with an average swell height of 2.2m and a solid 12.5s period, ensuring well-formed, powerful waves. The swell direction is predominantly from the WNW and NW, contributing to 61% of waves in the 1.5-2.5m range—ideal for intermediate to advanced surfers. WSW and SW swells also provide a good portion of rideable waves, though larger sets (over 2.5m) occur 12% of the time, offering challenging conditions for experienced riders. Wind conditions are favorable 33% of the time, with light to moderate offshore or cross-shore winds (0-20kph) from the N to ENE. However, stronger onshore winds (20-30kph) from the SW to W can occasionally degrade wave quality. Overall, December is a reliable month for quality surf, particularly when winds align, with a mix of medium-sized waves and occasional heavy days for those seeking more intensity.
