Seligman, MO 65745 Frost Dates
Seligman, MO: when does the frost end?
The last spring frost here typically falls around 04/18, about 233 days from today. Fall's first freeze usually shows up around 10/22, roughly 185 days after the last spring frost.
The USDA Plant Hardiness Zone Map puts Seligman in Zone 7a (0 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 Seligman's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.
Why 04/18 isn't a guarantee
04/18 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 05/03 and only about 1 year in 10 sees frost after that.
