Vancouver, WA 98665 Frost Dates
Vancouver, WA: when does the frost end?
Around 04/26 is the usual last spring frost, about 241 days away. Fall's first freeze usually shows up around 10/18, roughly 177 days after the last spring frost.
The USDA Plant Hardiness Zone Map puts Vancouver in Zone 8b (15 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 7 weeks until Vancouver's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.
The actual range around Vancouver's last frost
04/26 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 04/07 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 05/10 and only about 1 year in 10 sees frost after that.
