Kenai Fjords in December: what the park service says

December at Kenai Fjords swings between deep snow and rain. The park says storms dropping several feet of snow are common, but so are rainy midwinter days in the mid to upper 30s, and winter lows can reach -20°F. The temperate maritime climate comes from the Japanese current in the Gulf of Alaska. Sunlight off snow and ice is intense, so bring sunglasses.
