Rain and snow in South Viking
South Viking gets 18 inches of rain and melted snow a year. June is the wettest month and January the driest. Rain or snow falls on about 52 days a year.
About 135 frost-free days a year
In half of years the last 32° night comes by May 12 and the first one by September 26. That leaves about 135 frost-free days for gardens, shorter than 92% of U.S. towns.
Heating and cooling a home in South Viking
Engineers use “degree days” to estimate how hard a furnace or air conditioner works. In South Viking, 96% of that work is heating and 4% is cooling, so the furnace matters far more than the air conditioner.
Degree days measure how far each day’s average temperature falls below or rises above 65°, added up over a year. Source: NOAA station normals.
