Lake City, MI 49667 Frost Dates
Lake City, MI: when does the frost end?
Typically, the last spring freeze lands around 05/30, roughly 275 days out. Fall's first freeze usually shows up around 09/15, roughly 106 days after the last spring frost.
The USDA Plant Hardiness Zone Map puts Lake City in Zone 5a (-20 to -15°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 3 weeks until Lake City's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.
Why 05/30 isn't a guarantee
05/30 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 05/12 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 06/19 and only about 1 year in 10 sees frost after that.
