Bonanza, AR 72916 Frost Dates
Bonanza, AR: when does the frost end?
Around 03/25 is the usual last spring frost, about 209 days away. Fall's first freeze usually shows up around 11/06, roughly 224 days after the last spring frost.
Bonanza 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 Bonanza's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.
Why 03/25 isn't a guarantee
03/25 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 03/04 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 04/11 and only about 1 year in 10 sees frost after that.
