Lansing, MI: when does the frost end?

Zone 6a

The last spring frost here typically falls around 05/01, about 246 days from today. Fall's first freeze usually shows up around 10/13, roughly 162 days after the last spring frost.

Zone 6a (-10 to -5°F average annual minimum) comes from the USDA Plant Hardiness Zone Map; the frost dates above are the 1991-2020 normal at the nearest reporting NOAA station for Lansing, not a forecast for this year.

Stretching the season past the first frost

With roughly 7 weeks until Lansing's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.

Why 05/01 isn't a guarantee

05/01 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 04/18 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.
