Oregon, OH 43616 Frost Dates
Oregon, OH: when does the frost end?
Around 04/20 is the usual last spring frost, about 235 days away. Fall's first freeze usually shows up around 10/27, roughly 188 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 Oregon, not a forecast for this year.
Stretching the season past the first frost
With roughly 9 weeks until Oregon's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.
The actual range around Oregon's last frost
04/20 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 04/05 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 05/07 and only about 1 year in 10 sees frost after that.
