Devol, OK: when does the frost end?
Typically, the last spring freeze lands around 03/26, roughly 210 days out. Fall's first freeze usually shows up around 11/09, roughly 228 days after the last spring frost.
Devol sits in USDA Zone 8a (10 to 15°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 10 weeks until Devol's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.
Why 03/26 isn't a guarantee
03/26 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 03/08 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 04/14 and only about 1 year in 10 sees frost after that.
