Madalena do Mar in Portugal offers consistent surf conditions year-round, but the best months for surfers are typically from October to March, when ground swells dominate and wave heights are more substantial. During this period, the mean swell size ranges from 1.4m to 1.9m, with October and December standing out as particularly reliable months. Ground swells make up 70% or more of the swell activity, ensuring cleaner, more powerful waves. However, wind conditions tend to be less favorable, with good wind days occurring only around 30-40% of the time, meaning offshore winds are less frequent and cross-shore or onshore winds are more common. From April to September, the swell mix shifts toward wind swells, which can create less consistent and often choppier conditions. The mean swell size drops below 1.5m, reaching its lowest point in July and August (0.9m). While these months see slightly better wind conditions (good wind percentages improve to around 40-48%), the smaller, less powerful waves make them better suited for beginners or longboarders. September marks a transition period as ground swells begin to increase again, though wave heights remain moderate. For advanced surfers seeking stronger, cleaner waves, the winter months (November to February) are ideal despite the higher likelihood of challenging wind conditions. If you prioritize more manageable winds and don’t mind smaller swell sizes, late spring and summer (May to August) can still offer surfable days, particularly in the mornings when winds are lighter. Overall, Madalena do Mar is a year-round surf destination, but the most powerful and consistent conditions arrive with the winter swell season.
