Vila Nova de Milfontes - surf spot statistics

Vila Nova de Milfontes is a surf spot with consistent ground swells year-round, but the best conditions for surfers generally occur during the autumn and winter months. From October through February, ground swell dominates, with percentages ranging from 67% to 92%, ensuring powerful and clean waves. The mean swell size during these months is also favorable, averaging between 1.8m and 2.4m, with December and January offering the largest waves. Wind conditions improve slightly in October and November, with good wind days reaching 30-32%, though onshore winds remain a challenge throughout the year. Winter months like January and February have stronger swells but suffer from higher bad wind percentages (69-73%), meaning surfers may need patience for clean sessions. Spring and summer (April to August) see a decline in ground swell dominance, shifting toward wind swell, with smaller wave sizes (1.3m-1.8m) and fewer good wind days (below 23%). September marks a transition, with improving ground swell (48%) and slightly better winds (28% favorable). For the most reliable conditions, advanced surfers should target October through December, when solid ground swells and marginally better wind probabilities create the best balance of size and ridable waves. Summer is better suited for beginners due to smaller, less powerful waves, though wind swell and poor wind conditions can still make sessions inconsistent.

In December, Vila Nova de Milfontes offers solid surf conditions with an average swell height of 2.3m and a favorable average period of 12.6s, indicating powerful, well-organized waves. The swell is predominantly from the WNW and NW directions, providing consistent, clean waves, particularly in the 1.5–2.5m range, which accounts for a significant portion of the swell distribution. Wind conditions are ideal for surfing 30% of the time, with the most favorable winds being light offshore (NE to E) or light cross-shore (NW to WSW). However, stronger onshore winds from the SW and W can occasionally degrade wave quality, especially when speeds exceed 20kph. Overall, December delivers reliable, sizeable surf with good shape when winds cooperate, making it a prime month for experienced surfers seeking power and consistency.
