Burns, OR 97917 Frost Dates

When can you plant in Burns, OR?

Zone 6a

The last spring frost here typically falls around 06/07, about 283 days from today. The first fall frost typically arrives around 09/06, about 89 frost-free days later.

Zone 6a (-10 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 Burns, not a forecast for this year.

What to do before the first frost

About 1 week of growing season left in Burns before the first fall frost — a cold frame or row cover can stretch harvest weeks past that date.

Why 06/07 isn't a guarantee

06/07 is the middle of 30 years of NOAA records, not a promise. Plant by 05/21 and you're betting against frost in roughly 9 years out of 10. 06/28 is the safer bet, historically only a 1-in-10 chance of frost that late.
