Nazare - surf spot statistics

Nazaré, Portugal, is renowned for its massive waves, particularly during the winter months when powerful ground swells dominate. The best time for experienced surfers seeking large, clean waves is from November through February. During these months, ground swell prevalence is extremely high (77–92%), with mean swell sizes ranging from 2.2m to 2.5m. However, wind conditions are less favorable, with bad winds (onshore or cross-shore) occurring 60–64% of the time. Despite this, the sheer size and consistency of the swells make these months prime for big-wave surfing. From March to October, conditions become progressively less consistent, with a notable drop in ground swell dominance and smaller waves (1.4–2.2m). April to August sees the highest proportion of wind swells, which are generally less powerful and less desirable for Nazaré’s iconic surf. September and October offer a transition period with improving ground swells (47–66%) and slightly better wind conditions (39–40% good winds). While summer months (June–August) are less ideal for big waves, they may still attract surfers comfortable with smaller swells, though wind conditions remain mostly unfavorable. For serious surfers targeting Nazaré’s legendary waves, the winter season (November–February) is the peak window, despite the frequent onshore winds, as the raw power and size of the swells outweigh the wind drawbacks.

July at Nazaré offers relatively small but clean conditions compared to its notorious winter swells. The average swell height is 1.4m with a decent period of 8.9s, providing consistent but manageable waves. Swell direction is predominantly from the NW and WNW, making up the majority of rideable waves, with heights mostly in the 1-2.5m range (around 40% of the time). However, larger sets over 2.5m are rare (less than 1%). Winds are a mixed bag: only 29% of the time are they ideal for surfing (typically light offshore from the NNE to ENE). The worst winds come from the N and NNW, which can bring onshore gusts of 20-30kph (over 24% of the time). Expect mornings to be cleaner before NW sea breezes pick up in the afternoons. For advanced surfers, it’s a good time for more technical surfing on smaller, lined-up waves rather than Nazaré’s usual heavy barrels. Bring a step-up board for the occasional head-high NW pulses.
