Fort Wayne, IN 46802 Frost Dates
Fort Wayne, IN: when does the frost end?
Around 04/24 is the usual last spring frost, about 239 days away. Fall's first freeze usually shows up around 10/21, roughly 178 days after the last spring frost.
Fort Wayne sits in USDA Zone 6a (-10 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 Fort Wayne's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.
Why 04/24 isn't a guarantee
04/24 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 04/10 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.
