Comporta - surf spot statistics

Comporta, Portugal, offers varying surf conditions throughout the year, with the best months typically falling within the winter season. From January to March, the spot experiences the most consistent and powerful ground swells, with January showing the highest percentage (90%) of ground swell days and an average swell size of 2.1m. February and December also deliver strong conditions, with 2.0m swells and high ground swell dominance (88% and 84%, respectively). Wind conditions, however, are less favorable, with bad winds occurring 65-71% of the time during these peak swell months. Moving into spring and summer (April to August), ground swells decrease significantly, giving way to wind swells, which dominate from May to August. Swell size drops to around 1.1-1.6m, and wind conditions remain largely unfavorable (77-81% bad winds). The autumn months (September to November) see a gradual return of ground swells, with October and November offering a decent compromise between swell energy (1.6-1.8m) and slightly improved wind conditions (69% bad winds). The optimal window for surfing in Comporta is clearly winter, specifically January through March, when swell consistency, size, and quality are highest, despite the challenging winds. Late autumn (October-November) can also provide good sessions, though with smaller swells. Summer is the least reliable season for quality surf due to the predominance of weaker wind swells and onshore winds. For advanced surfers seeking powerful, clean waves, prioritizing winter months is essential, while intermediate surfers may find late autumn more manageable.

In January, Comporta offers solid surf conditions with an average swell height of 2.1m and a long-period swell averaging 13.0s, providing powerful, well-formed waves. The dominant swell direction comes from the WNW and NW, contributing to the majority of rideable waves, particularly in the 1.5–2.5m range, ideal for intermediate to advanced surfers. Offshore winds (ideal for surfing) occur about 35% of the time, predominantly from the NE to E sector, which helps keep the waves clean. However, strong onshore winds from the SW to W can occasionally disrupt conditions. Smaller, weaker swells from the W and NNW are less consistent but still contribute to surfable days. Overall, January delivers reliable, punchy waves with good shape, but wind conditions can be variable, making timing sessions around favorable wind windows key.
