Goose Lake, IA 52727 Frost Dates

When can you plant in Goose Lake, IA?

Zone 5a

Around 04/22 is the usual last spring frost, about 237 days away. The first fall frost typically arrives around 10/16, about 175 frost-free days later.

Zone 5a (-20 to -15°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 Goose Lake, not a forecast for this year.

What to do before the first frost

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

How much risk comes with planting early here

04/22 is the middle of 30 years of NOAA records, not a promise. Plant by 04/09 and you're betting against frost in roughly 9 years out of 10. 05/08 is the safer bet, historically only a 1-in-10 chance of frost that late.
