Aberdeen, MD 21001 Frost Dates
Aberdeen, MD: when does the frost end?
The last spring frost here typically falls around 04/10, about 225 days from today. Fall's first freeze usually shows up around 10/30, roughly 201 days after the last spring frost.
The USDA Plant Hardiness Zone Map puts Aberdeen in Zone 7b (5 to 10°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 9 weeks until Aberdeen's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.
Why 04/10 isn't a guarantee
04/10 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 03/27 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 04/30 and only about 1 year in 10 sees frost after that.
