Swedesboro, NJ 08085 Frost Dates
When can you plant in Swedesboro, NJ?
Typically, the last spring freeze lands around 04/02, roughly 217 days out. The first fall frost typically arrives around 11/10, about 224 frost-free days later.
The USDA Plant Hardiness Zone Map puts Swedesboro in Zone 7b (5 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 11 weeks of growing season left in Swedesboro before the first fall frost — a cold frame or row cover can stretch harvest weeks past that date.
Why 04/02 isn't a guarantee
04/02 is the middle of 30 years of NOAA records, not a promise. Plant by 03/19 and you're betting against frost in roughly 9 years out of 10. 04/13 is the safer bet, historically only a 1-in-10 chance of frost that late.
