Cody, NE 57574 Frost Dates

When can you plant in Cody, NE?

Zone 5a

The last spring frost here typically falls around 05/11, about 256 days from today. The first fall frost typically arrives around 10/01, about 143 frost-free days later.

Cody sits in USDA Zone 5a (-20 to -15°F average annual minimum). The dates above are NOAA's 1991-2020 normal at the nearest reporting station, a 30-year average, not a forecast.

What to do before the first frost

About 5 weeks of growing season left in Cody before the first fall frost — a cold frame or row cover can stretch harvest weeks past that date.

Why 05/11 isn't a guarantee

05/11 is the middle of 30 years of NOAA records, not a promise. Plant by 04/29 and you're betting against frost in roughly 9 years out of 10. 05/24 is the safer bet, historically only a 1-in-10 chance of frost that late.
