Salgueiros seasonal overview
Best Surf Season (October - March)
The North Atlantic roars to life during the autumn and winter months, bringing consistent, powerful swell to Salgueiros. With average wave heights ranging from 1.4m to 1.8m and periods averaging 11-12.7 seconds, these months deliver long-period, groundswell-dominated conditions. The dominant swell directions are from the WNW and NW, which wrap perfectly into the west-facing beach. Additionally, the frequency of offshore winds from the east (ENE, E, ESE, SE) peaks during this period, with ideal wind percentages between 39% and 49%. This combination creates clean, well-shaped waves that are often firing. The Azores High tends to weaken, allowing a parade of extratropical cyclones to track across the North Atlantic, generating consistent swell trains. December and January are the peak months for size and power.
Fair Surf Season (April and September)
These transitional months offer a mixed bag. April sees average swell heights dropping to 1.3m with a period of 10.9s, and ideal wind frequency at 30%. The swell is still solid but less consistent, and the winds begin to shift, with more northerly and northwesterly flow. September marks the start of the ramp-up, with average swell heights of 1.1m and periods of 10.4s, and ideal winds at 28%. Early season groundswell becomes more common as the first autumn storms develop. While conditions can be good, they are less reliable than the peak season.
Low Surf Season (May - August)
Summer brings a significant downturn in surf quality. Average wave heights hover around 0.9-1.1m with periods dropping to 8.8-9.9 seconds, indicating windswell-dominated conditions. The dominant swell direction is NW, but wave heights are small, and the period is short, resulting in weak, mushy waves. Onshore and cross-shore winds become more prevalent, with ideal wind frequencies dropping to 11-23%. The prevailing northerly and northwesterly winds (NNW, N, NW) often produce choppy conditions. The Azores High strengthens, diverting storm tracks away from the region. While occasional smaller swell windows can be found, especially early morning with lighter winds, this is generally a time for groveling or taking a break.

Conditions at Salgueiros in September
September: The Autumn Awakening
September marks the beginning of the transition back to solid surf. Average swell height rises to 1.1m, and the period increases to 10.4s, signaling the return of longer-period groundswell. The swell direction shows NW (39.3%) and WNW (42.0%) still dominant, but the W (11.5%) begins to play a role. Wave heights are predominantly in the 0.5-1.5m range, but there is a noticeable increase in 1.5-2m waves compared to summer months. Ideal wind frequency jumps to 28%, as the weather patterns become more changeable. The Azores High starts to shift, allowing early autumn storms to generate swell. Easterly winds from the ENE, E, and ESE become more common, providing clean, glassy conditions. This is a promising month for intermediate surfers, with consistent waist-to-chest-high waves and occasional head-high sets.
