Frost dates for Newport, IN, ZIP 47966
Typically, the last spring freeze lands around 04/30, roughly 245 days out. The first fall frost typically arrives around 10/12, about 164 frost-free days later.
The USDA Plant Hardiness Zone Map puts Newport in Zone 6a (-10 to -5°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 6a around Newport has about 6 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 04/30 isn't a guarantee
04/30 is the middle of 30 years of NOAA records, not a promise. Plant by 04/14 and you're betting against frost in roughly 9 years out of 10. 05/15 is the safer bet, historically only a 1-in-10 chance of frost that late.
