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.

January at Arrifana offers solid surf conditions with a dominant swell from the WNW and NW directions, providing consistent wave heights averaging 2.0m and a healthy 13s period, ensuring well-formed, powerful waves. The majority of swell energy comes in the 1.5-2.5m range, with W, WNW, and NW swells delivering the best waves—over 30% of the time, heights exceed 1.5m from these directions, making it ideal for intermediate to advanced surfers. Wind conditions are favorable 32% of the time, typically light to moderate (under 20kph) and often offshore from the NE to E quadrant. However, stronger winds (20-30kph+) from the N to NW can create choppier conditions, especially when paired with larger swells. Overall, January provides reliable surf with a good mix of clean and bigger days, though wind variations require selective timing for the best sessions.
