Jeffersonville, KY: when does the frost end?

Zone 7a

Around 04/19 is the usual last spring frost, about 234 days away. Fall's first freeze usually shows up around 10/20, roughly 184 days after the last spring frost.

Jeffersonville sits in USDA Zone 7a (0 to 5°F average annual minimum). The dates above are NOAA's 1991-2020 normal at the nearest reporting station, a 30-year average, not a forecast.

Stretching the season past the first frost

With roughly 8 weeks until Jeffersonville's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.

Why 04/19 isn't a guarantee

04/19 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 04/04 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 05/05 and only about 1 year in 10 sees frost after that.
