Crisfield, MD 21817 Frost Dates
Crisfield, MD: when does the frost end?
The last spring frost here typically falls around 03/31, about 215 days from today. Fall's first freeze usually shows up around 11/11, roughly 225 days after the last spring frost.
The USDA Plant Hardiness Zone Map puts Crisfield in Zone 8a (10 to 15°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 11 weeks until Crisfield's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.
Why 03/31 isn't a guarantee
03/31 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 03/17 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 04/13 and only about 1 year in 10 sees frost after that.
