Conditions at Seinesodden in December
December: Winter Solstice Swell
December locks in the winter pattern with full intensity. Average swell height is 6ft (1.8m), the period is 10.8 seconds, and ideal surf wind occurs 52% of the time. The waverose shows WSW at 17.5%, W at 11.4%, SW at 11.5%, WNW at 8.7%, NW at 6.9% and NNW at 4.9%, with a substantial amount of swell in the 1.5-2.5m range and occasional bigger pulses. SE wind is the dominant offshore flow at 23.7%, supported by SSE at 10.7% and ESE at 9.8%, so the beach remains remarkably clean for the time of year. The North Atlantic is now at the peak of its storminess, and each passing low sends strong W and NW groundswell toward the Norwegian coast. Air temperatures average -3.8°C, precipitation is the highest of the year at 6.20 mm/day, and water temperature drops to 5.8°C. Expect cold, powerful and often epic conditions as the year comes to a close.
