Frost dates for Port Angeles, WA, ZIP 98363
Typically, the last spring freeze lands around 03/12, roughly 196 days out. The first fall frost typically arrives around 11/19, about 252 frost-free days later.
The USDA Plant Hardiness Zone Map puts Port Angeles in Zone 8b (15 to 20°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
Zone 8b around Port Angeles has about 12 weeks left before the first fall frost — that's the usual window to get a cold frame up if you want to keep harvesting past it.
Why 03/12 isn't a guarantee
03/12 is the middle of 30 years of NOAA records, not a promise. Plant by 02/17 and you're betting against frost in roughly 9 years out of 10. 04/01 is the safer bet, historically only a 1-in-10 chance of frost that late.
