Indiana, PA 15701 Frost Dates
Indiana, PA: when does the frost end?
The last spring frost here typically falls around 05/10, about 255 days from today. Fall's first freeze usually shows up around 10/12, roughly 155 days after the last spring frost.
Indiana sits in USDA Zone 6b (-5 to 0°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 6 weeks until Indiana'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
05/10 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 04/24 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 05/28 and only about 1 year in 10 sees frost after that.
