Frost dates for Waynesville, MO, ZIP 65583
Typically, the last spring freeze lands around 04/15, roughly 230 days out. The first fall frost typically arrives around 10/21, about 185 frost-free days later.
The USDA Plant Hardiness Zone Map puts Waynesville 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 Waynesville has about 8 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 04/15 isn't a guarantee
04/15 is the middle of 30 years of NOAA records, not a promise. Plant by 03/29 and you're betting against frost in roughly 9 years out of 10. 05/02 is the safer bet, historically only a 1-in-10 chance of frost that late.
