Vader, WA 98581 Frost Dates
Vader, WA: when does the frost end?
Typically, the last spring freeze lands around 04/05, roughly 220 days out. Fall's first freeze usually shows up around 10/25, roughly 196 days after the last spring frost.
Vader sits in USDA Zone 8b (15 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.
Stretching the season past the first frost
With roughly 8 weeks until Vader's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.
Why 04/05 isn't a guarantee
04/05 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 03/12 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 05/04 and only about 1 year in 10 sees frost after that.
