Providence, RI 02911 Frost Dates
Providence, RI: when does the frost end?
The last spring frost here typically falls around 04/11, about 226 days from today. Fall's first freeze usually shows up around 10/30, roughly 199 days after the last spring frost.
Zone 6b (-5 to 0°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 Providence, not a forecast for this year.
Stretching the season past the first frost
With roughly 9 weeks until Providence's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.
Why 04/11 isn't a guarantee
04/11 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 04/01 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 04/23 and only about 1 year in 10 sees frost after that.
