64433, near Clyde, MO: the frost window

Zone 6a

The last spring frost here typically falls around 04/17, about 232 days from today. Fall's first freeze usually shows up around 10/20, roughly 184 days after the last spring frost.

Zone 6a (-10 to -5°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 Clyde, not a forecast for this year.

Stretching the season past the first frost

Clyde's growing season runs out in roughly 8 weeks — a cold frame or greenhouse kit is the usual way to keep cool-weather crops going past the first frost.

How much risk comes with planting early here

04/17 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 04/03 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 04/30 and only about 1 year in 10 sees frost after that.
