Monte Clerigo seasonal overview
Monte Clerigo in Portugal offers the best surf conditions during the winter months, particularly from November through February, when ground swells dominate with frequencies above 74%, reaching up to 90% in January. These months also see the largest mean swell sizes, averaging between 1.7m and 2.0m, providing powerful and consistent waves ideal for experienced surfers. However, wind conditions are generally poor during this period, with bad winds occurring 75–82% of the time, which can create choppy surf. The shoulder months of October and March still deliver solid ground swell presence (64% and 81%, respectively) with slightly better wind conditions, making them good alternatives. From April onward, the swell quality decreases significantly, with wind swells becoming more prevalent and mean sizes dropping below 1.6m. Summer months (June–August) have the smallest waves (1.0–1.1m) and the highest wind swell influence, making them less favorable for quality surfing. While September and October see a return of better ground swell percentages, the inconsistent wind conditions (22–25% good winds) mean surfers must time their sessions carefully. Overall, Monte Clerigo is a winter destination for those seeking powerful waves, despite the often challenging wind.

Conditions at Monte Clerigo in December
December at this spot offers solid surf conditions with an average swell height of 2.0m and a consistent period of 12.4s, indicating powerful and well-formed waves. The dominant swell directions are WNW and NW, which account for the majority of waves in the 1.5–2.5m range, providing quality setups for intermediate to advanced surfers. Smaller waves (0.5–1.5m) are present but less frequent, while larger swells (over 2.5m) occur occasionally, adding potential for more challenging sessions. Wind conditions are favorable only 21% of the time, with the best scenario being light offshore or cross-offshore winds, typically from the N/NE. However, stronger onshore winds (SW–W) can create choppy conditions, especially when exceeding 20kph. Expect a mix of clean and messy days, but when the wind aligns, this spot can deliver powerful, well-shaped waves. Keep an eye on forecasts for those optimal sessions.
