What stands out about Columbia’s climate
Compared with towns across the U.S., with Columbia’s place in Tennessee beside it.
What a year in Columbia feels like
Typical highs and lows by season and by month, from NOAA’s 30-year normals.
About 199 frost-free days a year
In half of years the last 32° night comes by April 10 and the first by October 27. Frost and day counts come from NOAA’s station at Columbia 3 Wnw, TN, 2.5 miles from the city’s center point, at about the same height.
The 2023 USDA map puts Columbia’s center in zone 7b: the coldest night of a typical winter, averaged over 1991–2020, reaches about 7°. Plant labels use the zone; frost dates tell you when to plant.

About 55 inches of rain a year
December is the wettest month and August the driest. Rain falls on about 126 days a year. Snow is rare: about 0.9" in a normal year at Columbia 3 Wnw, TN, so most winters see none.

Heating and cooling a home in Columbia
74% of the work is heating. Months averaging under 55° run from November through March.
Degree days add up how far each day’s average falls below (heating) or rises above (cooling) 65° over a year. NOAA normals at Columbia 3 Wnw, TN.
Living with Columbia’s climate
What the numbers mean for a garden, a free afternoon and a bad-weather day.
199 frost-free days in zone 7b. The last frost comes by Apr 10 in half of years, so many gardeners wait a week or two past that to set out tomatoes. The first fall frost comes by Oct 27.
Months with highs of 62–84° and lows of 40° or more: April, May, September and October. 1.0 miles of trails are waiting.

Warmer than it used to be
The last 30 years in Columbia averaged 0.9° warmer than the 1900s. The biggest change is in February (+1.8°).
A smaller shift than in 86% of U.S. towns.
Change by month
The two periods overlap (1991–2000 is in both), which makes the gap a little smaller than it would be between separate periods.
How Columbia compares
Against 12,954 U.S. towns of 2,500 or more (one per 5 km climate cell), with Columbia’s place among Tennessee’s.
