Columbia, KY 42715 Frost Dates
Columbia, KY: when does the frost end?
The last spring frost here typically falls around 04/05, about 220 days from today. Fall's first freeze usually shows up around 11/02, roughly 211 days after the last spring frost.
Columbia 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 9 weeks until Columbia's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.
How much risk comes with planting early here
04/05 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 03/21 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 04/24 and only about 1 year in 10 sees frost after that.
