Pedra Branca - surf spot statistics

Pedra Branca in Portugal is primarily a winter surf spot, with the best conditions occurring from November through February. During these months, ground swell dominates (74–91%), providing consistent and powerful waves, with mean swell sizes ranging from 2.0m to 2.2m. The wind conditions, however, are less favorable, with only 27–34% of days offering good offshore or cross-shore winds, while 66–73% of days have onshore or poor wind conditions that can disrupt wave quality. March and October serve as transition periods, where ground swells remain fairly reliable (63–84%) but swell size decreases slightly to 1.7–2.0m, and wind conditions improve marginally (27–30% good winds). The worst months for surfing are from May through September, when wind swells take over (52–83%), resulting in smaller, less consistent waves (1.1–1.4m) and very poor wind conditions (only 11–19% of days have favorable winds). For surfers seeking powerful, well-formed waves, the winter months are ideal, though patience is required for the right wind alignment. Intermediate surfers may find better consistency in late autumn or early spring when swells remain solid but conditions are slightly less extreme. Summer is generally only suitable for beginners or when wind conditions briefly align.

In May, Pedra Branca offers surfers a mix of conditions with an average swell height of 1.4m and a solid 10.1s wave period, indicating consistent, well-formed waves. The swell predominantly arrives from the west-northwest (WNW) and northwest (NW), contributing to around 38% of the waves in the 1-2.5m range, ideal for intermediate to advanced surfers. Smaller but still surfable waves (0.5-1.5m) from the west (W) and southwest (SW) account for roughly 20% of the distribution, providing variety. However, offshore winds—crucial for clean conditions—are somewhat rare in May, occurring only 17% of the time. The wind tends to blow from the north and northwest, often at 10-30kph, which can create choppy or cross-shore conditions, particularly with stronger northerlies. While larger swells (2m+) are infrequent (around 8% of the time), they can deliver powerful, hollow waves when they arrive. Surfers should monitor wind forecasts closely, as the best sessions will align with lighter offshore or light cross-shore winds. Overall, May provides decent surf opportunities, though consistency and wind conditions may require patience.
