60510, near Batavia, IL: the frost window

Zone 5b

The last spring frost here typically falls around 04/19, about 234 days from today. Fall's first freeze usually shows up around 10/23, roughly 185 days after the last spring frost.

Stretching the season past the first frost

Batavia'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

04/19 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 04/05 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 05/04 and only about 1 year in 10 sees frost after that.
