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.

March: Late-Winter Swell on the Wane

March brings the first signs of spring moderation, with average swell height dropping to 2.1 m and period to 12.4 s. WNW (23.0%) and NW (27.6%) still dominate, but the proportion of NW swell increases, which is less ideal for the straight WSW beach. Still, there is a healthy 7.7% from W and 1.9% from WSW, offering good swell windows. Offshore wind reliability eases slightly to 46%, still favorable. The main challenge is the increasing frequency of northerly wind (NNW at 13.7%, N at 18.6%) which can become side-shore or side-offshore, but it's the easterly quadrants that deliver the glassy conditions. Expect solid, punchy waves on the best days.
