Frost dates for Alda, NE, ZIP 68810

Zone 5b

Typically, the last spring freeze lands around 04/23, roughly 238 days out. The first fall frost typically arrives around 10/15, about 174 frost-free days later.

Alda sits in USDA Zone 5b (-15 to -10°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

Zone 5b around Alda has about 7 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 04/23 isn't a guarantee

04/23 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. 05/06 is the safer bet, historically only a 1-in-10 chance of frost that late.
