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.

November at Arrifana offers solid surf conditions with an average swell height of 1.7m and a favorable period of 11.8s, ensuring well-spaced, powerful waves. The dominant swell directions are NW and WNW, producing the highest proportion of rideable waves, particularly in the 1-2.5m range, ideal for intermediate to advanced surfers. WSW and SW swells also contribute, though with slightly less consistency. Wind conditions are key, with onshore winds (SSW to NW) appearing frequently, but clean offshore winds (NE to ESE) occur less often—only 29% of the time is wind truly ideal. However, moderate cross-shore winds (WNW-NW) can still provide decent sessions. Expect larger swells (2m+) primarily from NW-WNW, but be mindful of stronger winds accompanying these directions, which may create choppy faces. Overall, November delivers consistent, mid-sized waves with peaky sections, but selective timing around wind shifts will maximize quality.
