Watts, OK 74964 Frost Dates
Watts, OK: when does the frost end?
Typically, the last spring freeze lands around 03/31, roughly 215 days out. Fall's first freeze usually shows up around 11/02, roughly 216 days after the last spring frost.
Zone 7a (0 to 5°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 Watts, not a forecast for this year.
Stretching the season past the first frost
With roughly 9 weeks until Watts's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.
Why 03/31 isn't a guarantee
03/31 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 03/13 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 04/18 and only about 1 year in 10 sees frost after that.
