Porto Katsiki - surf spot statistics

Porto Katsiki in Greece is primarily a windswell-dominated spot, with very little ground swell influence throughout the year. The best months for surfers are generally from November to February, when wind swell frequency is highest and mean swell size approaches 0.8–0.9m. December and January offer the most consistent conditions, with wind swell occurring around 69–75% of the time, though wind conditions remain challenging, with bad onshore winds affecting 76–79% of days. February sees a slight drop in wind swell frequency (64%) but remains one of the better months. From March onward, wind swell activity decreases significantly, and the surf becomes far less reliable, with June through September being the least favorable due to low swell frequency (25–36%) and small mean sizes (0.4–0.5m). Summer months (May–September) are particularly poor, with very few rideable days and unfavorable winds persisting 83–88% of the time. Autumn (October–November) shows a slight uptick in wind swell activity, but conditions remain inconsistent. Overall, Porto Katsiki is a spot suited for experienced surfers willing to endure marginal conditions, with winter providing the best—though still limited—opportunities for surfable waves. Wind is a major limiting factor year-round, with clean offshore conditions rare (only 12–24% of days even in peak months).

October at Porto Katsiki offers generally small and inconsistent surf, with an average swell height of just 0.5m and a short 4.9s period, making it more suitable for beginners or longboarders rather than advanced surfers. The swell is predominantly from the west-northwest (WNW, NW, W) and southwest (SW, WSW), with the largest share of waves in the 0-1m range—NW and WSW directions contribute the most, occasionally reaching 1.5-2m but rarely exceeding that. Wind conditions are challenging, with only 15% of the time being ideal for surfing; the most frequent winds come from ENE, E, and NW at 10-20kph, often creating cross-shore or onshore chop. Stronger winds (20-30kph) from SE and NW directions can further deteriorate conditions. While there are occasional clean, rideable days when winds align off-shore (likely from the northeast quadrants), expect mostly small, weak waves with inconsistent power. Advanced surfers will find it underwhelming, but it’s a scenic spot for mellow sessions when conditions briefly align.
