Midlothian, IL 60445 Frost Dates

60445, near Midlothian, IL: the frost window

Zone 6a

Around 04/10 is the usual last spring frost, about 225 days away. Fall's first freeze usually shows up around 11/01, roughly 203 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 Midlothian, not a forecast for this year.

Stretching the season past the first frost

Midlothian's growing season runs out in roughly 9 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

04/10 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 03/30 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 04/26 and only about 1 year in 10 sees frost after that.
