Brookings, OR 95567 Frost Dates
Brookings, OR: when does the frost end?
Typically, the last spring freeze lands around 01/31, roughly 156 days out. Fall's first freeze usually shows up around 12/27, roughly 334 days after the last spring frost.
Brookings sits in USDA Zone 9b (25 to 30°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 17 weeks until Brookings's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.
Why 01/31 isn't a guarantee
01/31 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 03/20 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 12/14 and only about 1 year in 10 sees frost after that.
