Pilot Point, AK 99649 Frost Dates

When can you plant in Pilot Point, AK?

Zone 5a

Typically, the last spring freeze lands around 06/09, roughly 285 days out. The first fall frost typically arrives around 09/11, about 93 frost-free days later.

Zone 5a (-20 to -15°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 Pilot Point, not a forecast for this year.

What to do before the first frost

About 2 weeks of growing season left in Pilot Point before the first fall frost — a cold frame or row cover can stretch harvest weeks past that date.

Why 06/09 isn't a guarantee

06/09 is the middle of 30 years of NOAA records, not a promise. Plant by 05/28 and you're betting against frost in roughly 9 years out of 10. 06/22 is the safer bet, historically only a 1-in-10 chance of frost that late.
