Frost Risk Probability

Based on 25 years of NOAA weather station data from 2 stations

Too early frost risk Safe to Plant Feb 7 → Dec 8 305 frost-free days Protect crops frost returns Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec Safe: Mar 8 Protect by: Dec 22

Beginners: Plant frost-sensitive crops (tomatoes, peppers, squash) after the "Safe" date on the left. Harvest or cover them before the "Protect by" date on the right. Hardy crops (lettuce, peas, kale) can go in the yellow transition zones.

How to read this table: "Conservative" means you're safe from frost 9 out of 10 years — best for beginners and frost-sensitive crops. "Average year" is the typical date. "Aggressive" means only 1 in 10 years is that warm — experienced gardeners with frost protection can try these dates.
