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 August, Alvor offers generally small to medium-sized waves with an average swell height of 1.0m and a decent period of 9.0s, providing reasonably clean and rideable conditions. The predominant swell direction is from the NW, accounting for the majority of waves, especially in the 0.5-1.5m range, with some larger sets up to 2.5m. Swells from the WNW and NW also contribute significantly, often producing the best quality waves for surfing. Wind conditions are favorable 36% of the time, with lighter winds (below 20kph) from the NNE, NE, and E offering cleaner surfaces, while stronger winds from the NW and NNW can create choppier conditions. Overall, August delivers mostly manageable waves for intermediate surfers, with occasional bigger days when NW swells combine with lighter winds for better shape. The spot is best suited for surfers comfortable with smaller, softer waves, though occasional punchier sets can provide more challenge.
