“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 State Line
State Line gets 63 inches of rain and melted snow a year. July is the wettest month and October the driest. Rain or snow falls on about 92 days a year.
About 228 frost-free days a year
In half of years the last 32° night comes by March 26 and the first one by November 8. That leaves about 228 frost-free days for gardens, longer than 85% of U.S. towns.
Heating and cooling a home in State Line
Engineers use “degree days” to estimate how hard a furnace or air conditioner works. In State Line, 52% of that work is heating and 48% 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 State Line 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 State Line averaged 0.5° warmer than the 1900s. The biggest change is in February (+1.4°). The shift is smaller than in 97% of U.S. towns.

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 43° to 62°. July is the most reliable, staying within 5°.

Temperatures and rainfall come from NOAA’s gridded climate normals for State Line itself (about a 3-mile square). Snow, frost dates and day counts come from NOAA’s weather station at Buckatunna 1 Ne, MS (8 mi, snow) and Chatom, AL (13 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.
