Seward, NE 68434 Frost Dates
When can you plant in Seward, NE?
Around 04/26 is the usual last spring frost, about 241 days away. The first fall frost typically arrives around 10/12, about 169 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 Seward, not a forecast for this year.
What to do before the first frost
About 6 weeks of growing season left in Seward before the first fall frost — a cold frame or row cover can stretch harvest weeks past that date.
Why 04/26 isn't a guarantee
04/26 is the middle of 30 years of NOAA records, not a promise. Plant by 04/11 and you're betting against frost in roughly 9 years out of 10. 05/07 is the safer bet, historically only a 1-in-10 chance of frost that late.
