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.

Pedra Branca in September offers surfers a mix of conditions, with the most consistent swells coming from the west-northwest (WNW) and northwest (NW). The average swell height is 1.3m, supported by a solid 10.6s period, which indicates well-spaced, powerful waves suitable for intermediate to advanced surfers. The majority of swell energy falls in the 0.5-2.5m range, with WNW and NW directions dominating—accounting for over 50% of the waves in this size bracket, ideal for generating clean, rideable surf. Wind conditions are less favorable, with only 19% of days offering ideal offshore or light cross-shore breezes. The predominant winds come from the north (N) and northwest (NW), often blowing at 10-30kph, which can create choppy or less clean conditions. However, mornings may provide cleaner sessions before the wind picks up. Overall, September delivers decent waves with good energy, but surfers should monitor wind forecasts closely to maximize the best windows for smooth, groomed conditions.
