Sheboygan, WI 53026 Frost Dates
When can you plant in Sheboygan, WI?
Typically, the last spring freeze lands around 05/02, roughly 247 days out. The first fall frost typically arrives around 10/21, about 169 frost-free days later.
The USDA Plant Hardiness Zone Map puts Sheboygan in Zone 5b (-15 to -10°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 8 weeks of growing season left in Sheboygan before the first fall frost — a cold frame or row cover can stretch harvest weeks past that date.
Why 05/02 isn't a guarantee
05/02 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. 05/19 is the safer bet, historically only a 1-in-10 chance of frost that late.
