Zone 7a

The last spring frost here typically falls around 04/24, about 239 days from today. The first fall frost typically arrives around 10/21, about 179 frost-free days later.

Zone 7a (0 to 5°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 Lebanon, not a forecast for this year.

What to do before the first frost

About 8 weeks of growing season left in Lebanon before the first fall frost — a cold frame or row cover can stretch harvest weeks past that date.

The actual range around Lebanon's last frost
