Frost dates for Waverly, KS, ZIP 66871

Zone 6b

Around 04/08 is the usual last spring frost, about 223 days away. The first fall frost typically arrives around 10/30, about 202 frost-free days later.

The USDA Plant Hardiness Zone Map puts Waverly in Zone 6b (-5 to 0°F average annual minimum); frost dates are NOAA's 1991-2020 station normal, not this year's forecast.

What to do before the first frost

Zone 6b around Waverly has about 9 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 04/08 isn't a guarantee

04/08 is the middle of 30 years of NOAA records, not a promise. Plant by 03/24 and you're betting against frost in roughly 9 years out of 10. 04/22 is the safer bet, historically only a 1-in-10 chance of frost that late.
