Kastro Point - surf spot statistics

Kastro Point in Greece is predominantly a windswell-driven surf spot, with ground swells being virtually nonexistent throughout the year. The best conditions for surfing occur during the winter months, particularly from November to February, when windswell frequency peaks at 57%–62%, and the mean swell size ranges from 0.7m to 0.9m. December stands out as the most consistent month, offering the highest swell frequency (62%) and the largest average swell size (0.9m). However, wind conditions are challenging year-round, with bad onshore winds dominating 90%–95% of the time, limiting ideal surf sessions. The worst conditions are found in summer (June–September), where windswell drops below 35%, swell size diminishes to 0.4m–0.5m, and unfavorable winds persist over 95% of the time. While autumn and early winter (October–December) provide slightly better waves, wind quality remains poor, requiring patience for rare clean sessions. Advanced surfers may still score rideable windswell during winter, but overall, Kastro Point is inconsistent and heavily dependent on occasional wind alignments. For the most surfable conditions, target late autumn through early winter, but expect strong onshore winds to be the norm.

October at Kastro Point offers generally small but rideable surf with an average swell height of 0.6m and a modest 4.7s period. The primary swell directions are SW and WSW, which contribute the most consistent waves, particularly in the 0.5-1.5m range (12.42% and 7.77% respectively). Larger swells (1.5-2.5m) are rare but occur occasionally from W and WNW directions, though waves over 2.5m are almost nonexistent. Wind conditions are less favorable, with only 5% being ideal for surfing—typically light offshore or cross-offshore breezes from N to ENE. Strong onshore winds (10-30kph) from E to SE are more common, potentially ruining otherwise clean conditions. Overall, expect small, playful waves with occasional mid-sized days, but patience is key due to inconsistent wind quality.
