Niagara Falls, NY 14303 Frost Dates
When can you plant in Niagara Falls, NY?
Around 05/01 is the usual last spring frost, about 246 days away. The first fall frost typically arrives around 10/19, about 167 frost-free days later.
The USDA Plant Hardiness Zone Map puts Niagara Falls in Zone 6b (-5 to 0°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 7 weeks of growing season left in Niagara Falls before the first fall frost — a cold frame or row cover can stretch harvest weeks past that date.
Why 05/01 isn't a guarantee
05/01 is the middle of 30 years of NOAA records, not a promise. Plant by 04/21 and you're betting against frost in roughly 9 years out of 10. 05/15 is the safer bet, historically only a 1-in-10 chance of frost that late.
