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.

October: Springing to Life

October is a turning point as the North Atlantic storm track intensifies. Average swell height climbs to 1.9 m with a period of 11.4 s. The swell direction shifts favorably: NW still accounts for the most (35.4%), but W swell grows to 8.3% and WSW to 2.4%, while WNW holds at 24.6%. This is a more balanced spectrum. Offshore wind blows 47% of the time, with a notable increase in east winds (ESE 4.8%, SE 4.4%, S 5.5%, but especially N at 18.8% and NNE at 6.9% — the latter being excellent offshore directions). The combination of building swell and improving wind odds sets the stage for classic Nazare sessions. Expect solid, long-period waves with occasional clean faces as the Azores High begins to weaken.
