When can you plant in Chevak, AK?
Typically, the last spring freeze lands around 06/05, roughly 281 days out. The first fall frost typically arrives around 09/03, about 88 frost-free days later.
The USDA Plant Hardiness Zone Map puts Chevak in Zone 4a (-30 to -25°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

Why 06/05 isn't a guarantee
06/05 is the middle of 30 years of NOAA records, not a promise. Plant by 05/20 and you're betting against frost in roughly 9 years out of 10. 06/26 is the safer bet, historically only a 1-in-10 chance of frost that late.
