Wright City, OK 74766 Frost Dates

74766, near Wright City, OK: the frost window

Zone 8a

Around 04/09 is the usual last spring frost, about 224 days away. Fall's first freeze usually shows up around 10/29, roughly 201 days after the last spring frost.

Zone 8a (10 to 15°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 Wright City, not a forecast for this year.

Stretching the season past the first frost

Wright City's growing season runs out in roughly 9 weeks — a cold frame or greenhouse kit is the usual way to keep cool-weather crops going past the first frost.

Why 04/09 isn't a guarantee

04/09 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 03/23 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.
