Redmond, OR 97753 Frost Dates
Redmond, OR: when does the frost end?
Typically, the last spring freeze lands around 06/09, roughly 285 days out. Fall's first freeze usually shows up around 09/14, roughly 98 days after the last spring frost.
Zone 6b (-5 to 0°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 Redmond, not a forecast for this year.
Stretching the season past the first frost
With roughly 2 weeks until Redmond's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.
Why 06/09 isn't a guarantee
06/09 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 05/17 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 06/26 and only about 1 year in 10 sees frost after that.
