Hymera, IN 47858 Frost Dates
Hymera, IN: when does the frost end?
The last spring frost here typically falls around 04/08, about 223 days from today. Fall's first freeze usually shows up around 10/27, roughly 201 days after the last spring frost.
Hymera 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 9 weeks until Hymera's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.
Why 04/08 isn't a guarantee
04/08 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 03/25 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.
