When is the best weather to visit Wheat Ridge?

Normal highs sit between 65°F and 85°F in May, June, September and October. Of those, October has the fewest days with rain (6).

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 Wheat Ridge?

In Wheat Ridge, the last spring frost (32°F) comes after May 5 in half of years and after May 18 in one year in ten; the first autumn frost comes before October 5 in half of years and before September 20 in one year in ten.

First autumn frost, half of years before
October 51 year in 10 before September 20; 9 in 10 before October 18

NOAA puts the median frost-free season at 151 days, and the season without a hard freeze (28°F) at 170 days.

A hard freeze (28°F) comes after April 25 in half of springs and before October 14 in half of autumns.

The USDA's 2023 Plant Hardiness Zone Map puts Wheat Ridge in zone 6a across its 2 ZIP code areas (6a in 80033, the largest). By the map's own method, the average of each year's coldest night over 1991-2020, Wheat Ridge's NOAA station is in zone 6a: the coldest night of a typical year reaches −7°F (28 complete years).

Has Wheat Ridge been warmer than normal lately?

2025 averaged 51.9°F, 1.6°F above the 1991-2020 normal of 50.3°F. 3 of the 5 complete years since 2021 ran warmer than the normal.

How does Wheat Ridge's climate compare?

Wheat Ridge is warmer than 80 of the other 124 places with their own NOAA record in Colorado, and wetter than 82. Across the 7,247 U.S. stations with normals, its annual mean of 50.3°F is warmer than 42%.

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

Which places near Wheat Ridge 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.
