Waldo, AR 71770 Frost Dates
When can you plant in Waldo, AR?
Typically, the last spring freeze lands around 03/31, roughly 215 days out. The first fall frost typically arrives around 11/02, about 218 frost-free days later.
Waldo sits in USDA Zone 8b (15 to 20°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.
What to do before the first frost
About 9 weeks of growing season left in Waldo before the first fall frost — a cold frame or row cover can stretch harvest weeks past that date.
Why 03/31 isn't a guarantee
03/31 is the middle of 30 years of NOAA records, not a promise. Plant by 03/09 and you're betting against frost in roughly 9 years out of 10. 04/17 is the safer bet, historically only a 1-in-10 chance of frost that late.
