Brookville, KS: when does the frost end?

Zone 6b

Typically, the last spring freeze lands around 04/27, roughly 242 days out. Fall's first freeze usually shows up around 10/16, roughly 170 days after the last spring frost.

Zone 6b (-5 to 0°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 Brookville, not a forecast for this year.

Stretching the season past the first frost

With roughly 7 weeks until Brookville's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.

Why 04/27 isn't a guarantee

04/27 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 04/14 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 05/10 and only about 1 year in 10 sees frost after that.

Brookville against the rest of the dataset
