Lincoln, MI 48745 Frost Dates
Lincoln, MI: when does the frost end?
Typically, the last spring freeze lands around 05/19, roughly 264 days out. Fall's first freeze usually shows up around 09/29, roughly 133 days after the last spring frost.
Lincoln sits in USDA Zone 5b (-15 to -10°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 5 weeks until Lincoln's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.
Why 05/19 isn't a guarantee
05/19 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 05/03 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 06/02 and only about 1 year in 10 sees frost after that.
