“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 Sun
Sun gets 27 inches of rain and melted snow a year. June is the wettest month and January the driest. Rain or snow falls on about 56 days a year.
About 171 frost-free days a year
In half of years the last 32° night comes by April 25 and the first one by October 15. That leaves about 171 frost-free days for gardens, shorter than 59% of U.S. towns.
Heating and cooling a home in Sun
Engineers use “degree days” to estimate how hard a furnace or air conditioner works. In Sun, 77% of that work is heating and 23% is cooling.
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 Sun 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 Sun averaged 0.7° warmer than the 1900s. The biggest change is in January (+2.5°). The shift is smaller than in 88% of U.S. towns.
Change by month1991–2020 average minus 1901–2000 average, at Sun’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 40° to 57°. June is the most reliable, staying within 11°.

Temperatures and rainfall come from NOAA’s gridded climate normals for Sun itself (about a 3-mile square). Snow, frost dates and day counts come from NOAA’s weather station at Sun City, KS (1 mi, snow) and Wilmore 16se, KS (19 mi, frost, heat and degree days). Normals are 30-year averages, not a forecast.
