Arrifana - surf spot statistics

Arrifana in Portugal offers consistent surf conditions year-round, but the best months for quality waves are typically from October through March, aligning with the Atlantic swell season. During these months, ground swell dominates (74-90% of the time), with mean swell heights ranging from 1.7m to 2.0m, providing powerful and well-formed waves. Winter months, particularly December and January, deliver the largest swells (2.0m on average) and the highest ground swell frequency (82-90%), making them ideal for experienced surfers seeking bigger waves. However, wind conditions are less favorable in winter, with only 26-32% of days having good winds, meaning offshore or light winds are relatively rare, and cross-shore or onshore winds are more common. Spring (April-May) and autumn (September-November) offer a balance of ground and wind swells, with September and October seeing improving wind conditions (31-32% good wind days) and decent swell sizes (1.5m-1.7m). Summer (June-August) is the least consistent, with wind swells prevailing (70-81%) and smaller waves (1.0m-1.1m), though it can still provide fun sessions for beginners or longboarders, especially in early morning when winds are lighter. Overall, advanced surfers will find the best conditions from late autumn to early spring, while intermediate and beginner surfers may prefer the smaller, more forgiving waves of late spring or early autumn when winds are slightly more favorable.

March at Arrifana offers solid surf conditions with a consistent average swell height of 1.8m and a favorable period of 12.1s, indicating powerful, well-spaced waves. The dominant swell directions are WNW and NW, producing the highest proportion of rideable waves, particularly in the 1-2.5m range, which accounts for the majority of conditions. These swells are clean and well-organized, though larger sets (over 2.5m) are less frequent. Wind conditions are mixed—only 26% of the time are they ideal (typically light offshore or sideshore from the east quadrant). However, northerly and northwesterly winds are more common, often blowing at 10-30kph, which can create choppiness, especially at higher speeds. The best sessions occur when winds are light or from the ENE-E, coinciding with the dominant WNW swell for clean, hollow waves. Bigger days require experience due to the power of the Atlantic swells, but the spot handles size well. Overall, March delivers reliable surf with occasional excellent days when wind and swell align.
