Tawas City, MI 48764 Frost Dates
Tawas City, MI: when does the frost end?
Around 05/08 is the usual last spring frost, about 253 days away. Fall's first freeze usually shows up around 10/05, roughly 148 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 Tawas City, not a forecast for this year.
Stretching the season past the first frost
With roughly 5 weeks until Tawas City's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.
Why 05/08 isn't a guarantee
05/08 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 04/26 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 05/26 and only about 1 year in 10 sees frost after that.
