Alvor - surf spot statistics

Alvor in Portugal offers surfable conditions year-round, but the best months for surfers seeking quality waves and favorable winds are typically from October to March. During this period, ground swell dominates, with percentages ranging from 62% in October and April to 88% in January, ensuring more consistent and powerful waves. The mean swell size is also larger, averaging 1.4m to 1.9m, with the biggest waves occurring in January, February, and December (1.9m). Wind conditions are less ideal, with bad winds (onshore or cross-shore) prevailing around 65-70% of the time, but there are still plenty of rideable days with good offshore winds (30-35%). The shoulder months of September and April can still provide decent surf, albeit with smaller swells (1.1m-1.5m) and slightly better wind conditions (38% good winds in September). From May to August, the surf quality drops significantly as wind swells take over, resulting in smaller, less consistent waves (1.0m-1.2m) despite marginally better wind conditions (33-36% good winds). July and August see the highest wind swell influence (81% and 74%) but remain the worst months for serious surfers due to weak swells. Overall, winter months (November-February) are prime for experienced surfers chasing solid ground swells, while intermediate surfers may find late autumn (October) and early spring (March-April) more forgiving.

In May, Alvor offers surfable conditions with an average swell height of 1.2m and a solid 10.0s period, providing consistent and manageable waves for intermediate to advanced surfers. The swell is predominantly from the WNW and NW directions, generating the most favorable wave heights (1-2.5m) around 40% of the time, with occasional larger sets. WSW and SW swells also contribute, though less frequently. Wind conditions are ideal for surfing 29% of the time, with lighter offshore or cross-offshore winds from the E to SE sectors. However, stronger NW to NNW winds (20-30+ kph) can create choppier conditions, especially in the afternoons. Overall, May delivers a mix of clean, mid-sized waves and occasional wind-affected sessions—best capitalized in the mornings when winds are lighter.
