Westmoreland, KS 66549 Frost Dates

66549, near Westmoreland, KS: the frost window

Zone 6a

Around 04/18 is the usual last spring frost, about 233 days away. Fall's first freeze usually shows up around 10/19, roughly 183 days after the last spring frost.

The USDA Plant Hardiness Zone Map puts Westmoreland in Zone 6a (-10 to -5°F average annual minimum); frost dates are NOAA's 1991-2020 station normal, not this year's forecast.

Stretching the season past the first frost

Westmoreland's growing season runs out in roughly 7 weeks — a cold frame or greenhouse kit is the usual way to keep cool-weather crops going past the first frost.

Why 04/18 isn't a guarantee

04/18 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 04/04 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 05/02 and only about 1 year in 10 sees frost after that.
