Anderson, IN 46015 Frost Dates
Anderson, IN: when does the frost end?
The last spring frost here typically falls around 04/19, about 234 days from today. Fall's first freeze usually shows up around 10/23, roughly 186 days after the last spring frost.
The USDA Plant Hardiness Zone Map puts Anderson in Zone 6a (-10 to -5°F average annual minimum); frost dates are NOAA's 1991-2020 station normal, not this year's forecast.
Stretching the season past the first frost
With roughly 8 weeks until Anderson'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
04/19 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 04/03 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.
