Cadott, WI 54727 Frost Dates

When can you plant in Cadott, WI?

Zone 4b

Around 05/01 is the usual last spring frost, about 246 days away. The first fall frost typically arrives around 10/08, about 158 frost-free days later.

The USDA Plant Hardiness Zone Map puts Cadott in Zone 4b (-25 to -20°F average annual minimum); frost dates are NOAA's 1991-2020 station normal, not this year's forecast.

What to do before the first frost

About 6 weeks of growing season left in Cadott before the first fall frost — a cold frame or row cover can stretch harvest weeks past that date.

Why 05/01 isn't a guarantee

05/01 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.
