Hubbard, OR 97032 Frost Dates
When can you plant in Hubbard, OR?
Around 03/16 is the usual last spring frost, about 200 days away. The first fall frost typically arrives around 11/14, about 242 frost-free days later.
Zone 8b (15 to 20°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 Hubbard, not a forecast for this year.
What to do before the first frost
About 11 weeks of growing season left in Hubbard before the first fall frost — a cold frame or row cover can stretch harvest weeks past that date.
Why 03/16 isn't a guarantee
03/16 is the middle of 30 years of NOAA records, not a promise. Plant by 02/21 and you're betting against frost in roughly 9 years out of 10. 04/07 is the safer bet, historically only a 1-in-10 chance of frost that late.
