Oxford, MI 48371 Frost Dates
Oxford, MI: when does the frost end?
Around 04/29 is the usual last spring frost, about 244 days away. Fall's first freeze usually shows up around 10/20, roughly 172 days after the last spring frost.
The USDA Plant Hardiness Zone Map puts Oxford in Zone 6a (-10 to -5°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 8 weeks until Oxford'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 04/16 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 05/14 and only about 1 year in 10 sees frost after that.
