“Wet days” have at least 0.01" of rain or melted snow. “Snow on ground” counts days with 1" or more. The 30-year range is the coldest and warmest that month’s average temperature got between 1991 and 2020.
Rain and snow in Norway
Norway gets 28 inches of rain and melted snow a year. June is the wettest month and January the driest. Rain or snow falls on about 88 days a year. Snow covers the ground about 58 days of the year.
About 153 frost-free days a year
In half of years the last 32° night comes by May 3 and the first one by October 3. That leaves about 153 frost-free days for gardens, shorter than 78% of U.S. towns.
Heating and cooling a home in Norway
Engineers use “degree days” to estimate how hard a furnace or air conditioner works. In Norway, 88% of that work is heating and 12% 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.
Norway and its neighbors
Norway borders 3 towns with climate data. January nights across them vary by 0.3°. Vermillion has the coldest January nights (10°) and Gayville the hottest July afternoons (86°). Norway’s January low is 10° and its July high 86°.
Temperatures and rain come from NOAA’s 5 km grid, so each town gets its own value.
How Norway compares
Compared with every U.S. town and city on TownTapestry, each counted once.
Warmer than it used to be
The last 30 years in Norway averaged 0.7° warmer than the 1900s. The biggest change is in January (+2.5°). The shift is smaller than in 92% of U.S. towns.
Change by month1991–2020 average minus 1901–2000 average, at Norway’s spot on NOAA’s grid
How much a month can swing
A normal is an average, and real years wander around it. March swings the most: between 1991 and 2020 its average temperature ranged from 28° to 52°. August is the most reliable, staying within 9°.

Temperatures and rainfall come from NOAA’s gridded climate normals for Norway itself (about a 3-mile square). Snow, frost dates and day counts come from NOAA’s weather station at Yankton 2 E, SD (16 mi, snow) and Vermillion 2 Se, SD (8 mi, frost, heat and degree days). Normals are 30-year averages, not a forecast. Source: NOAA NCEI U.S. Climate Normals, 1991–2020 and 1901–2000.
