When is the best weather to visit Columbia?

Normal highs sit between 65°F and 85°F in April, May, June, September and October. Of those, September has the fewest days with rain (7).

That is a measurement, not a recommendation: it counts the months whose normal afternoon high sits between 65°F and 85°F, where a light layer is enough by day.

When is the last frost in Columbia?

In Columbia, the last spring frost (32°F) comes after April 7 in half of years and after April 21 in one year in ten; the first autumn frost comes before October 29 in half of years and before October 16 in one year in ten.

First autumn frost, half of years before
October 291 year in 10 before October 16; 9 in 10 before November 11

NOAA puts the median frost-free season at 205 days, and the season without a hard freeze (28°F) at 226 days.

A hard freeze (28°F) comes after March 28 in half of springs and before November 6 in half of autumns.

The USDA's 2023 Plant Hardiness Zone Map puts Columbia in zone 6b across its 3 ZIP code areas (6b in 65203, the largest). By the map's own method, the average of each year's coldest night over 1991-2020, Columbia's NOAA station is in zone 6b: the coldest night of a typical year reaches −3°F (30 complete years).

How sunny is Columbia?

Over a year 75% of the sunlight that would reach the ground under clear skies gets through the clouds in the area around Columbia, 4.2 kWh per square metre a day. July is the sunniest month (83%) and February the cloudiest (67%). Among the 459 U.S. places of 50,000 or more, that ranks tied 304th (with 25 others) in sunshine.

How much heating and cooling does Columbia need?

A normal year in Columbia brings 4,681 heating degree days, 13% fewer than the median U.S. place (5,373), and 1,448 cooling degree days, 60% more than the median (908). Five months need 300 or more heating degree days, a monthly mean of about 55°F or colder. For gardens and crops, NOAA counts 4,226 growing degree days a year above 50°F.

Has Columbia been warmer than normal lately?

2025 averaged 56.4°F, 0.4°F above the 1991-2020 normal of 56.0°F. 5 of the 5 complete years since 2021 ran warmer than the normal.

How does Columbia's climate compare?

Columbia is warmer than 89 of the other 133 places with their own NOAA record in Missouri, and wetter than 37. Across the 7,247 U.S. stations with normals, its annual mean of 56.0°F is warmer than 64%.

In the Köppen classification computed from these normals, Columbia is Dfa: continental, no dry season, hot summer. What the classes mean.

Which places near Columbia share this climate record?

5 places have no NOAA station with 1991-2020 normals of their own, and this station is the nearest full record. A place's own climate can differ from these figures, by several degrees where it sits much higher or lower than the station, nearer the coast, or inside a large city's heat; for the larger places the next nearest records are named with their yearly mean, so the spread around them is visible, and places of 50,000 or more have their own page with NOAA's gridded normals.
