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.

In June, Nazaré offers relatively smaller but consistent surf conditions, averaging a 1.4m swell height with a solid 9.5s period—indicating clean, well-spaced waves. The dominant swell direction is from the NW-WNW, contributing to 70-80% of the waves, mostly in the 1-2.5m range, making it surfable but not reaching the extreme winter sizes. Winds are a mixed bag: 30% of the time they're favorable (light offshore N/NE or calm), but the rest can bring onshore NW or NNW breezes at 10-30kph, which may create choppier conditions. Expect smaller, playful waves with occasional overhead sets, best suited for intermediate surfers or those looking for a more relaxed session compared to Nazaré’s legendary winter peaks. Watch for wind shifts, as mornings often provide cleaner conditions before afternoon breezes pick up.
