“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 Arapahoe
Arapahoe gets 23 inches of rain and melted snow a year. July is the wettest month and January the driest. Rain or snow falls on about 74 days a year. Snow covers the ground about 31 days of the year.
About 157 frost-free days a year
In half of years the last 32° night comes by May 1 and the first one by October 7. That leaves about 157 frost-free days for gardens, shorter than 74% of U.S. towns.
Heating and cooling a home in Arapahoe
Engineers use “degree days” to estimate how hard a furnace or air conditioner works. In Arapahoe, 86% of that work is heating and 14% 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.
How Arapahoe compares

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 20° to 40°. July is the most reliable, staying within 10°.

Temperatures and rainfall come from NOAA’s gridded climate normals for Arapahoe itself (about a 3-mile square). Snow, frost dates and day counts come from NOAA’s weather station at Elwood 8 S, NE (12 mi, snow) and Edison, NE (6 mi, frost, heat and degree days). Normals are 30-year averages, not a forecast.
