“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 Denmark
Denmark gets 44 inches of rain and melted snow a year. June is the wettest month and February the driest. Rain or snow falls on about 138 days a year. Snow covers the ground about 67 days of the year.
About 171 frost-free days a year
In half of years the last 32° night comes by May 2 and the first one by October 21. That leaves about 171 frost-free days for gardens, shorter than 59% of U.S. towns.
Heating and cooling a home in Denmark
Engineers use “degree days” to estimate how hard a furnace or air conditioner works. In Denmark, 92% of that work is heating and 8% 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.
Denmark and its neighbors
Denmark borders 4 towns with climate data. January nights across them vary by 0.9°. Dorset has the coldest January nights (18°) and Jefferson the hottest July afternoons (81°). Denmark’s January low is 19° and its July high 81°.
Temperatures and rain come from NOAA’s 5 km grid, so each town gets its own value.
How Denmark 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 Denmark averaged 1.7° warmer than the 1900s. The biggest change is in December (+3.0°). The shift is larger than in 82% of U.S. towns.
Change by month1991–2020 average minus 1901–2000 average, at Denmark’s spot on NOAA’s grid
How much a month can swing
A normal is an average, and real years wander around it. February swings the most: between 1991 and 2020 its average temperature ranged from 10° to 37°. September is the most reliable, staying within 8°.

Temperatures and rainfall come from NOAA’s gridded climate normals for Denmark itself (about a 3-mile square). Snow, frost dates and day counts come from NOAA’s weather station at Dorset, OH (4 mi, snow) and Ashtabula Co Airport, OH (3 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.
