North Logan, UT 84341 Frost Dates

When can you plant in North Logan, UT?

Zone 6a

Typically, the last spring freeze lands around 05/08, roughly 253 days out. The first fall frost typically arrives around 10/02, about 144 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 North Logan, not a forecast for this year.

What to do before the first frost

About 5 weeks of growing season left in North Logan before the first fall frost — a cold frame or row cover can stretch harvest weeks past that date.

Why 05/08 isn't a guarantee

05/08 is the middle of 30 years of NOAA records, not a promise. Plant by 04/24 and you're betting against frost in roughly 9 years out of 10. 05/29 is the safer bet, historically only a 1-in-10 chance of frost that late.
