Conditions at Porzcarn in January
January: Midwinter Muscle
January is Porzcarn at its heaviest. Average swell height sits at 7ft (2.2m) and the average period is a punchy 12.0s, putting this month squarely in the powerful long-period category. The waverose is loaded: W swell accounts for 25.2% of all readings, WNW follows at 15.9% and WSW adds 10.3%, so around half of all observations come from the ideal swell window. A significant share of the W and WNW energy falls in the 5-8ft (1.5-2.5m) range, meaning regular solid surf. The wind story is less forgiving. Offshore ENE-E-ESE flow only shows up for a small fraction of the time, with ideal conditions at just 15%. The onshore WSW, W, WNW and NW quadrant blows more than 30% of the time, often straight into the beach. When a transient ridge of high pressure pushes in from the east, though, the wind turns offshore, and January serves up clean, heavy, lined-up winter waves on a cold Atlantic. Air temps average 8.1°C, water temp is 10.6°C, and precipitation runs at 3.38 mm/day, so expect chilly, wet sessions and full winter rubber.
