“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 Bismark
Bismark gets 29 inches of rain and melted snow a year. June is the wettest month and January the driest. Rain or snow falls on about 79 days a year. Snow covers the ground about 56 days of the year.
About 165 frost-free days a year
In half of years the last 32° night comes by April 28 and the first one by October 12. That leaves about 165 frost-free days for gardens, shorter than 65% of U.S. towns.
Heating and cooling a home in Bismark
Engineers use “degree days” to estimate how hard a furnace or air conditioner works. In Bismark, 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.
Bismark and its neighbors
Bismark borders 3 towns with climate data. January nights across them vary by 0.9°. Elkhorn has both the coldest January nights (12°) and the hottest July afternoons (85°). Bismark’s January low is 13° and its July high 85°.
Temperatures and rain come from NOAA’s 5 km grid, so each town gets its own value.
How Bismark 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 Bismark averaged 0.8° warmer than the 1900s. The biggest change is in January (+2.6°). The shift is smaller than in 84% of U.S. towns.

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 30° to 52°. June is the most reliable, staying within 10°.

Temperatures and rainfall come from NOAA’s gridded climate normals for Bismark itself (about a 3-mile square). Snow, frost dates and day counts come from NOAA’s weather station at Dodge, NE (11 mi, snow) and West Pt, NE (13 mi, frost, heat and degree days). Normals are 30-year averages, not a forecast.
