Luz, Portugal, offers consistent surf conditions year-round, but the best months for surfers seeking powerful, clean waves are from October through March. During this period, ground swell dominates (63-89%), with mean swell sizes ranging from 1.5m to 2.0m, peaking in December and January. Winter months bring the largest and most consistent waves, though wind conditions are less favorable (only 28-35% good wind days), often resulting in onshore or cross-shore winds that can create choppy surfaces. The shoulder months of October and November, as well as March, provide a good balance between swell size and frequency while still avoiding the worst wind conditions. From April to September, swell consistency decreases, with wind swells becoming more dominant (37-82%) and mean sizes dropping to 1.0m-1.5m. Summer months (June-August) see the smallest waves (1.0m-1.1m), but wind conditions improve slightly (35-38% good wind days), making them suitable for beginners or longboarders. September marks the transition back to larger swells, though wind issues persist. Advanced surfers will prioritize winter for powerful, clean ground swells, while intermediate riders might prefer late autumn or early spring for a compromise between size and wind quality.
