Centuria, WI 54024 Frost Dates
Frost dates for Centuria, WI, ZIP 54024
Typically, the last spring freeze lands around 05/04, roughly 249 days out. The first fall frost typically arrives around 10/08, about 156 frost-free days later.
The USDA Plant Hardiness Zone Map puts Centuria in Zone 4a (-30 to -25°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
Zone 4a around Centuria has about 6 weeks left before the first fall frost — that's the usual window to get a cold frame up if you want to keep harvesting past it.
Why 05/04 isn't a guarantee
05/04 is the middle of 30 years of NOAA records, not a promise. Plant by 04/20 and you're betting against frost in roughly 9 years out of 10. 05/18 is the safer bet, historically only a 1-in-10 chance of frost that late.
