Auburn, ME 04274 Frost Dates
When can you plant in Auburn, ME?
Around 05/03 is the usual last spring frost, about 248 days away. The first fall frost typically arrives around 10/07, about 157 frost-free days later.
The USDA Plant Hardiness Zone Map puts Auburn in Zone 5b (-15 to -10°F average annual minimum); frost dates are NOAA's 1991-2020 station normal, not this year's forecast.
What to do before the first frost
About 6 weeks of growing season left in Auburn before the first fall frost — a cold frame or row cover can stretch harvest weeks past that date.
Why 05/03 isn't a guarantee
05/03 is the middle of 30 years of NOAA records, not a promise. Plant by 04/23 and you're betting against frost in roughly 9 years out of 10. 05/16 is the safer bet, historically only a 1-in-10 chance of frost that late.
