Nazare - surf spot statistics

Best Surf Season (October - March)

The North Atlantic roars to life during these months, delivering consistent, powerful swell from the W to WNW bands. Average wave heights range from 2.1 to 2.4 m with periods climbing into the 12-13 s range, often feeding the Nazare canyon with long-period groundswell. Offshore winds from the E/NE quadrant blow cleanly across the face 46-52% of the time, sculpting the waves into hollow, ridable gems. This is when the spot truly lives up to its big-wave reputation.

Fair Surf Season (April & September)

These shoulder months see a transition in the North Atlantic storm track. April still harvests moderate swell (1.8 m avg, 11.2 s) with a mix of W and NW energy, but offshore wind reliability drops to 37%. September offers a refreshing uptick after summer, with average swell climbing back to 1.5 m and period to 10.5 s, plus a solid 45% ideal wind frequency. Both months can produce fun, rippable sessions, especially when a late-season low or early autumn depression aligns with a light east wind.

Low Surf Season (May - August)

Summer settles in with a persistent ridge of high pressure over the Azores, suppressing storm activity across the North Atlantic. Swell heights drop to 1.3-1.5 m, periods shorten to 8.7-10.0 s, and the wind rarely swings offshore — ideal wind percentages languish between 30-37%. The dominant swell direction shifts to NW and NNW, which wrap into the bay with less power and often get chopped by the prevailing northerly wind. It's a time for small-wave gear and patience; the rare easterly breeze can salvage a marginal day.

June: Flat Spell Begins

June is the start of the lowest surf season at Nazare. Average swell height drops to 1.4 m and period to 9.3 s, with most swell coming from the NW (41.2%) and NNW (23.9%). The percentage of W swell declines further to 6.1%, and WSW to 1.8%. Offshore wind reliability hits a yearly low of 32%, as the dominant trade wind pattern sets in — N (24.3%) and NNW (33.8%) blow consistently, creating choppy, onshore conditions much of the time. The rare day with an easterly breeze and a pulse of W swell can produce small, clean waves, but they are few and far between. This is a month for equipment maintenance, not epic sessions.
