Colony, AL 35033 Frost Dates
Colony, AL: when does the frost end?
Around 04/06 is the usual last spring frost, about 221 days away. Fall's first freeze usually shows up around 10/29, roughly 205 days after the last spring frost.
Zone 8a (10 to 15°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 Colony, not a forecast for this year.
Stretching the season past the first frost
With roughly 9 weeks until Colony's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.
How much risk comes with planting early here
04/06 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 04/24 and only about 1 year in 10 sees frost after that.
