East Dundee, IL 60192 Frost Dates

When can you plant in East Dundee, IL?

Zone 5b

Around 04/30 is the usual last spring frost, about 245 days away. The first fall frost typically arrives around 10/13, about 163 frost-free days later.

East Dundee sits in USDA Zone 5b (-15 to -10°F average annual minimum). The dates above are NOAA's 1991-2020 normal at the nearest reporting station, a 30-year average, not a forecast.

What to do before the first frost

About 7 weeks of growing season left in East Dundee before the first fall frost — a cold frame or row cover can stretch harvest weeks past that date.

Why 04/30 isn't a guarantee

04/30 is the middle of 30 years of NOAA records, not a promise. Plant by 04/17 and you're betting against frost in roughly 9 years out of 10. 05/16 is the safer bet, historically only a 1-in-10 chance of frost that late.
