Conditions at Seinesodden in January
January: Deep-Water Winter Power
January sits at the heart of the cold-season peak. The average swell height is 6ft (1.9m) with a mean period of 11.3 seconds, placing most surf in the powerful long-period category. The waverose is loaded with WSW energy at 18.5%, SW at 13.6% and W at 11.4%, while the pure optimal window of W, WNW, NW and NNW combines to 28.6% of the observations. This means there is almost always wave energy moving through the Norwegian Sea, and when the W/NW component lines up with a long-period groundswell, Seinesodden sees solid 6-8ft (1.8-2.4m) waves. Wind-wise, SE dominates at 24.4%, with ESE at 10.4% and SSE at 10.3%, giving the spot a clean offshore flow 52% of the time. The cold high pressure that often sits over Scandinavia is your friend here, grooming the surf while the North Atlantic lows do the heavy lifting. Average air temperature is -5.1°C (min -22.6°C, max 4.7°C), precipitation averages 6.06 mm/day and the water temperature is 4.4°C. Dress for an Arctic session and charge.
