Colorado Springs, CO 80995 Frost Dates

80995, near Colorado Springs, CO: the frost window

Zone 5b

Around 05/03 is the usual last spring frost, about 248 days away. Fall's first freeze usually shows up around 10/08, roughly 158 days after the last spring frost.

Zone 5b (-15 to -10°F average annual minimum) comes from the USDA Plant Hardiness Zone Map; the frost dates above are the 1991-2020 normal at the nearest reporting NOAA station for Colorado Springs, not a forecast for this year.

Stretching the season past the first frost

Colorado Springs's growing season runs out in roughly 6 weeks — a cold frame or greenhouse kit is the usual way to keep cool-weather crops going past the first frost.

Why 05/03 isn't a guarantee

05/03 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 04/22 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 05/15 and only about 1 year in 10 sees frost after that.
