Gambell, AK 99742 Frost Dates
Gambell, AK: when does the frost end?
Around 06/05 is the usual last spring frost, about 281 days away. Fall's first freeze usually shows up around 09/03, roughly 88 days after the last spring frost.
The USDA Plant Hardiness Zone Map puts Gambell in Zone 4b (-25 to -20°F average annual minimum); frost dates are NOAA's 1991-2020 station normal, not this year's forecast.
Stretching the season past the first frost
With roughly 1 week until Gambell's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.
Why 06/05 isn't a guarantee
06/05 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 05/20 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 06/26 and only about 1 year in 10 sees frost after that.
