Amoreira - surf spot statistics

Amoreira in Portugal offers surfable conditions year-round, but the best months for quality waves and favorable wind conditions are typically from October through March. During this period, ground swell dominates (64-90%), providing powerful, clean waves with mean swell sizes ranging from 1.5m to 2.0m, peaking in January and December. Wind conditions are far from perfect, but late autumn and winter still have the highest percentages of good winds (22-25%) compared to the rest of the year. The worst months for surfing are June, July, and August, when wind swell becomes predominant (70-81%), wave size drops to 1.0-1.1m, and bad wind conditions prevail (83-84%). Spring (April-May) and early autumn (September) serve as transition periods, with declining ground swell influence but manageable wave heights. If you’re looking for consistency and size, target the winter months, but be prepared for challenging winds—October and November offer a slightly better balance of swell and wind conditions compared to deep winter. Summer is best avoided unless you’re after small, less predictable waves.

October at Amoreira offers decent surf conditions with an average swell height of 1.5m and a solid period of 11.3s, indicating well-formed, powerful waves. The primary swell directions are NW and WNW, contributing the most to surfable waves (1-2.5m range), while SW and WSW swells also provide occasional clean sets. Wind conditions are favorable for surfing 25% of the time, with lighter offshore or sideshore winds from the N, NE, and E sectors being the most ideal. However, stronger onshore winds from the W and SW can occasionally disrupt conditions, especially at higher speeds. Overall, October delivers consistent, mid-sized waves with clean conditions more likely in the mornings before winds pick up. Advanced surfers will find the best sessions when NW swells align with lighter NE winds, offering long, well-shaped waves.
