L'Embarcadore seasonal overview
Best Surf Season (October - March)
This is the undisputed peak season for L'Embarcadore. As the North Atlantic roars to life with a relentless procession of deep extratropical cyclones, average swell heights climb from 1.6m in October to over 2.0m in December and January. Wave periods frequently reach 10-14 seconds, delivering powerful, long-period groundswells that, despite their predominantly W to WNW origin, wrap into the south-facing beach with enough energy to produce solid, hollow waves. The catch? Ideal offshore winds (N to NW) are scarce, occurring only 17-26% of the time. However, when a cold front clears the Bay of Biscay and a strong high-pressure ridge builds from the north, the combination of pumping swell and glassy conditions can be absolutely epic. The NAO index often drives the storm track; a negative NAO steers lows further south, increasing the likelihood of optimal S/SW swell angles and offshore winds.
Fair Surf Season (April - May & September)
Transitional months where the Atlantic storm track begins to shift north (spring) or becomes more active again (early autumn). Average swell heights drop to 1.2-1.4m with periods between 9.4-10.3s – rideable but less powerful. The wind patterns become more favorable, with offshore wind percentages rising to 33-37%. April and May see a higher frequency of NE to E winds that are actually cross-shore to slightly offshore for this south-facing spot, creating clean but often small, fun-sized waves. September offers a similar setup with a hint of returning autumn energy. These months are perfect for loggers, fish, and grovelers when the swell lines up.
Low Surf Season (June - August)
Summer is the calmest period. The Azores High dominates, pushing the storm track well north of the Bay of Biscay. Swell heights average just 1.0-1.1m with short periods of 8.5-8.9s, often resulting in weak, mushy waves. While offshore wind conditions are most common (42-47%) thanks to frequent N to NW breezes, the lack of significant swell energy means even the cleanest days produce only small, grovelly waves. A rare southwesterly swell from a distant low can occasionally inject some punch, but consistent surf is not the norm. This is the time for longboard cruising and enjoying the beach – not for charging.

September: First Signs of Autumn Swell
September marks the transition back to more active surf. Average swell height rises to 1.2m with a period of 9.8s. The swell direction begins to broaden: while WNW (38.4%) and W (28.2%) still dominate, there is a slight increase in NW (10.2%) and the first hints of WSW (5.0%) and SW (1.2%) groundswells. The wind pattern remains favorable with 37% ideal offshore, driven by NW (9.3%) and NNE (7.1%) breezes. The wave period is now in the average to powerful range, making for punchy, rideable waves. The combination of cleaner winds and beginning of the autumn swell train makes September a hidden gem for dedicated surfers.
