Porto Covo is a consistent surf spot with reliable conditions year-round, but the best months for surfers seeking powerful, clean waves are typically February and December. During these months, ground swell dominates (97% in February, 89% in December), delivering mean swell sizes of 2.2m—ideal for intermediate to advanced surfers. The winter months (November to March) generally see the largest and cleanest swells, with ground swell percentages above 90%, though wind conditions are less favorable, with bad winds occurring 75-82% of the time. Offshore winds are rare but most likely in summer, particularly in July and August, when good wind conditions peak at 48-52%. However, summer swells are smaller (1.1-1.2m), mostly wind-driven, and better suited for beginners or longboarders. Shoulder seasons like September and October offer a balance, with decent ground swell (65-72%) and moderate wind conditions, though swell size drops to 1.2-1.6m. May and June see a mix of ground and wind swells, but inconsistent conditions make them less reliable for quality surf. Overall, winter provides the most powerful waves, while summer brings cleaner but weaker conditions—optimal timing depends on skill level and preference for wave power versus wind quality.
