Conditions at Vouliagmeni in January
January: Midwinter South-Swell Pulses
January sits at the heart of the Greek surf season. The average swell height reaches 0.9m (3ft) and the average period climbs to 5.1s, the highest of the year. Swell direction is dominated by NNE (26.1%) and SSW (18.9%), but for this south-facing beach the SSW portion is what matters; SSW alone supplies more than 8% of waves in the 1-2.5m (3-8ft) range, with S and SSE adding a little more. Offshore winds from N/NNE/NW/NNW blow around half the time, though the data classify only 20% of the month as ideal for surfing. When a deep Mediterranean low sends longer-period SSW swell under those north winds, the bay can produce punchy, clean head-high waves. Air temperatures average 9.1°C, water remains 15.7°C, and 1.98mm/day of rain keeps the hills green, but the surf is worth braving the cold.
