Golconda, IL 42047 Frost Dates
Golconda, IL: when does the frost end?
Around 04/03 is the usual last spring frost, about 218 days away. Fall's first freeze usually shows up around 10/30, roughly 207 days after the last spring frost.
Golconda sits in USDA Zone 7a (0 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 Golconda'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
04/03 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 03/18 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 04/21 and only about 1 year in 10 sees frost after that.
