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 January, Alvor offers solid surf conditions with an average swell height of 1.9m and a favorable period of 12.9s, indicating well-formed, powerful waves. The dominant swell directions are from the WNW and NW, contributing to the majority of surfable waves, particularly in the 1.5-2.5m range, making it ideal for intermediate to advanced surfers. Cross-shore and light onshore winds (SSW to WSW) are present 33% of the time, providing cleaner conditions, while stronger winds from the N/NE can occasionally create choppier surf. Expect a good mix of mid-sized swells with occasional larger sets, especially from the W and NW. Overall, January provides consistent surf with a decent window for clean conditions, though wind quality varies—patience and timing will reward surfers with quality sessions.
