Conditions at Byberg in January
January: Midwinter Power and Cross-Shore Chaos
January is deep winter at Byberg. The average height pushes to 5ft (1.6m) and the average period to 8.4s, which puts most of the surf in the punchy, rideable range and sets up some powerful northwest swell. Around 37% of all swell comes from the exposed W, WNW, NW and NNW window, with W (13.3%), WNW (11.1%) and NW (11.2%) all well represented. The rest of the spectrum is weighted toward S/SE and SW directions, which are less useful at this west-northwest-facing beach and often reflect short-fetch or locally generated waves.
Wind is the limiting factor. The offshore quadrant from E through SSE makes up about 34% of observations, but the number of truly ideal windows is only 12%. Strong SE winds can be howling, and onshore NNW winds are the single most common wind direction at 11.8%, with another 5% from W and 4.8% from NW adding to the mess. Water temperature sits at 6.1°C and air averages 2.2°C, so the session is as much a battle against the cold as it is against the forecast. Pick your moments after a low passes and winds clock E/SE - those are the days 5-8ft (1.5-2.4m) WNW/NW lines can be glassy and heavy.
