Ekwok sits in USDA Zone 4b (-25 to -20°F average annual minimum). The dates above are NOAA's 1991-2020 normal at the nearest reporting station, a 30-year average, not a forecast.

What to do before the first frost

About 3 weeks of growing season left in Ekwok before the first fall frost — a cold frame or row cover can stretch harvest weeks past that date.

Why 05/26 isn't a guarantee

05/26 is the middle of 30 years of NOAA records, not a promise. Plant by 05/09 and you're betting against frost in roughly 9 years out of 10. 06/11 is the safer bet, historically only a 1-in-10 chance of frost that late.
