Rabo de Peixe in Portugal is a surf spot with consistent swell year-round, but the conditions vary significantly between seasons. The best months for surfing are typically from October to March when ground swell dominates (54–73%) and mean swell size ranges from 1.8m to 2.5m, peaking in December with the largest waves (2.5m). During this period, the swell is powerful and clean, though wind conditions are generally unfavorable (83–87% bad winds), with onshore winds frequently affecting wave quality. The winter months, particularly December and January, offer the biggest and most consistent waves but require patience for rare clean days with offshore winds (15% good wind conditions). Spring (April–June) and early autumn (September) see a transition with decreasing ground swell and increasing wind swell, leading to smaller waves (1.2–1.9m). Summer (June–August) is the least favorable, with the smallest swells (1.0–1.2m) and mostly wind-driven conditions. While good wind conditions improve slightly in summer and early autumn (20–23%), the swell quality drops significantly. Advanced surfers will find the biggest and most powerful waves in winter, despite challenging winds, while intermediates may prefer late autumn or early spring when swells are still decent but slightly more manageable. Overall, Rabo de Peixe is a year-round destination for committed surfers, with peak conditions in winter for those seeking larger, more powerful waves.
