Conditions at Porto Katsiki in January
January: Midwinter Swell Windows
January is the heart of the Mediterranean winter and the closest Porto Katsiki gets to consistent surf. The average swell height reaches its seasonal max at 3.3ft (1.0m), but the 5.5s average period remains stubbornly short, so most of what arrives is windswell rather than groundswell. The S/SSW/SW corridor, which aims straight at the SSW-facing beach, carries 23.2% of all directional energy, while the dominant NW sector (22.1%) is far less useful and adds mostly lumpy background sea state. Ideal offshore winds from the N/NNE/NE/NNW quadrant blow 20% of the time; when one of these dry cold-air bursts lines up behind a passing low, expect clean, punchy 2-4ft (0.6-1.2m) conditions in the bay. Average air temperature is 12.2°C with water at 16.0°C, so a 4/3 wetsuit and boots are usually the right call.
