December: Peak Winter for the Jæren Coast
December is prime time at Bore. Average wave heights sit at 1.5m (4.9ft), periods are a solid 8.3s, and ideal offshore wind conditions reach 15%, tied as the best of the year. The west-facing swell window is fully active, with WSW at 11.9%, W at 13.0%, WNW at 12.6% and NW at 12.0% combining to hammer the beach with consistent Atlantic groundswell. When the NAO is strongly positive, low-pressure systems line up like trains across the North Atlantic and Bore can see well overhead surf for days. The wind rose shows SE at 11.5% and ESE at 8.0%, giving real offshore potential, while NNW also shows 11.4% and can spoil things with cross-shore energy. Air temps average a frigid 3.3°C, water temps drop to 7.9°C, and precipitation peaks at 6.69mm/day. Daylight is short, but the ocean is full of life.
