Warwick, RI 02852 Frost Dates
When can you plant in Warwick, RI?
Around 04/27 is the usual last spring frost, about 242 days away. The first fall frost typically arrives around 10/15, about 171 frost-free days later.
Warwick sits in USDA Zone 7a (0 to 5°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.
What to do before the first frost

Why 04/27 isn't a guarantee
04/27 is the middle of 30 years of NOAA records, not a promise. Plant by 04/14 and you're betting against frost in roughly 9 years out of 10. 05/11 is the safer bet, historically only a 1-in-10 chance of frost that late.
