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.

October at Pedra Branca offers solid surf conditions with a consistent swell averaging 1.7m and a healthy period of 11.3s, indicating well-organized and powerful waves. The dominant swell directions are W to NW, with the highest frequency of rideable waves (1.5m+) coming from WNW and NW—these swells produce the best size and energy, often in the 1.5-2.5m range. Smaller swells (1-1.5m) are also frequent, while larger sets (over 2.5m) are less common but occasionally provide heavier, more challenging waves. Wind conditions are somewhat mixed, with ideal offshore or light cross-shore winds (favorable for surfing) occurring only 28% of the time. The winds tend to blow from the N to NW, which can be onshore or cross-shore, occasionally disrupting wave quality. However, the consistent swell and long-period energy ensure that October is a reliable month for surfers, particularly those comfortable with overhead waves and variable wind conditions. Focus on early mornings or days with lighter NW winds for cleaner setups.
