Zone 7a (0 to 5°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 Hopkinsville, not a forecast for this year.

What to do before the first frost

Zone 7a around Hopkinsville 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 04/04 isn't a guarantee

04/04 is the middle of 30 years of NOAA records, not a promise. Plant by 03/18 and you're betting against frost in roughly 9 years out of 10. 04/19 is the safer bet, historically only a 1-in-10 chance of frost that late.
