Durango, CO 81302 Frost Dates
When can you plant in Durango, CO?
Around 05/21 is the usual last spring frost, about 266 days away. The first fall frost typically arrives around 10/02, about 134 frost-free days later.
The USDA Plant Hardiness Zone Map puts Durango in Zone 6b (-5 to 0°F average annual minimum); frost dates are NOAA's 1991-2020 station normal, not this year's forecast.
What to do before the first frost
About 5 weeks of growing season left in Durango before the first fall frost — a cold frame or row cover can stretch harvest weeks past that date.
Why 05/21 isn't a guarantee
05/21 is the middle of 30 years of NOAA records, not a promise. Plant by 05/07 and you're betting against frost in roughly 9 years out of 10. 06/07 is the safer bet, historically only a 1-in-10 chance of frost that late.
