Purcell, OK 73080 Frost Dates
Purcell, OK: when does the frost end?
Around 04/04 is the usual last spring frost, about 219 days away. Fall's first freeze usually shows up around 11/02, roughly 210 days after the last spring frost.
Purcell sits in USDA Zone 7b (5 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 9 weeks until Purcell's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.
Why 04/04 isn't a guarantee
04/04 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 03/18 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 04/24 and only about 1 year in 10 sees frost after that.
