Delhi, NY: when does the frost end?

Zone 5b

Typically, the last spring freeze lands around 05/19, roughly 264 days out. Fall's first freeze usually shows up around 10/01, roughly 132 days after the last spring frost.

Delhi sits in USDA Zone 5b (-15 to -10°F average annual minimum). The dates above are NOAA's 1991-2020 normal at the nearest reporting station, a 30-year average, not a forecast.

Stretching the season past the first frost

With roughly 5 weeks until Delhi'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

05/19 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 05/01 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 06/03 and only about 1 year in 10 sees frost after that.

Delhi against the rest of the dataset
