Vouliagmeni, Greece, is a surf spot that primarily relies on wind swells, as ground swells are virtually absent throughout the year. The best conditions for surfers occur when wind swells are present, but the spot faces significant challenges due to consistently poor wind conditions, with over 95% of days being unfavorable across all months. The mean swell size remains small, typically ranging between 0.5m and 0.8m, with the largest swells occurring in the winter months (December to February) at around 0.7m-0.8m. However, even during these months, the likelihood of rideable waves is limited, as wind swells only account for about 58-59% of days, and the rest are either too small or completely flat. Spring and summer (April to September) see even weaker conditions, with wind swells dropping to 30-39% frequency and swell sizes averaging just 0.5m-0.6m. Autumn (October-November) brings a slight increase in wind swell activity (46-54%) but still suffers from nearly constant onshore or choppy winds. Overall, Vouliagmeni is not a particularly reliable surf destination, but if forced to pick the best window, late autumn to winter (November-February) offers marginally better chances due to slightly higher wind swell frequency and bigger wave heights—though even then, clean conditions are rare. Surfers should temper expectations and consider it a spot for beginners or very occasional sessions when local winds briefly align.
