Orfordville, WI 53576 Frost Dates

When can you plant in Orfordville, WI?

Zone 5b

Around 04/29 is the usual last spring frost, about 244 days away. The first fall frost typically arrives around 10/12, about 165 frost-free days later.

Zone 5b (-15 to -10°F average annual minimum) comes from the USDA Plant Hardiness Zone Map; the frost dates above are the 1991-2020 normal at the nearest reporting NOAA station for Orfordville, not a forecast for this year.

What to do before the first frost

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

Why 04/29 isn't a guarantee

04/29 is the middle of 30 years of NOAA records, not a promise. Plant by 04/14 and you're betting against frost in roughly 9 years out of 10. 05/14 is the safer bet, historically only a 1-in-10 chance of frost that late.
