Zone 5b (-15 to -10°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 Ballard, not a forecast for this year.
What to do before the first frost
About 5 weeks of growing season left in Ballard before the first fall frost — a cold frame or row cover can stretch harvest weeks past that date.
Why 05/19 isn't a guarantee
05/19 is the middle of 30 years of NOAA records, not a promise. Plant by 05/01 and you're betting against frost in roughly 9 years out of 10. 06/15 is the safer bet, historically only a 1-in-10 chance of frost that late.
