Hustadvika • Statistics for January

January: The Deep-Winter Engine

January is the statistical peak of the Hustadvika year. The average swell height reaches 2.2m (7.2ft), while the average period hits 11.9s - a powerful, long-period signal that this is open ocean groundswell, not local wind chop. The dominant swell directions are W at 18.2%, NNW at 13.1%, WSW at 12.9%, and WNW and NW at 9.5% each. That puts over half of all observations in the preferred W/NW window for a coastline facing west-northwest. As the low-pressure conveyor belt rolls southeast across the North Atlantic, Hustadvika receives frequent head-high-to-double-overhead (6-8ft/1.8-2.4m) waves, with the occasional XL event pushing past 2.5m. Winds are ideal 42% of the time. The classic January setup is a post-frontal high-pressure ridge over Scandinavia: the swell is still running from the northwest while the wind clocks offshore from SE/SSE/E/ESE, turning the raw ocean into clean, hollow lines. Air temperature averages 2.7°C with lows near -6.6°C; precipitation is frequent at 4.99mm/day. Water temperature sits at 6.3°C, so thick suits, hoods, and cold-water resolve are part of the deal. When everything lines up, this is as good as it gets in Norway.
