Southern View, IL 62662 Frost Dates
Southern View, IL: when does the frost end?
Typically, the last spring freeze lands around 04/14, roughly 229 days out. Fall's first freeze usually shows up around 10/20, roughly 187 days after the last spring frost.
The USDA Plant Hardiness Zone Map puts Southern View in Zone 6b (-5 to 0°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 Southern View's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.
Why 04/14 isn't a guarantee
04/14 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 04/01 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 04/29 and only about 1 year in 10 sees frost after that.
