Kalamazoo, MI 49041 Frost Dates
Kalamazoo, MI: when does the frost end?
The last spring frost here typically falls around 04/29, about 244 days from today. Fall's first freeze usually shows up around 10/20, roughly 173 days after the last spring frost.
Kalamazoo sits in USDA Zone 6a (-10 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 8 weeks until Kalamazoo's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.
Why 04/29 isn't a guarantee
04/29 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 04/12 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 05/18 and only about 1 year in 10 sees frost after that.
