Frost Risk Probability

Based on 30 years of NOAA weather station data from 3 stations

Too early frost risk Safe to Plant May 4 → Oct 6 155 frost-free days Protect crops frost returns Apr May Jun Jul Aug Sep Oct Nov Safe: May 18 Protect by: Oct 16

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.

Planting Strategy Last Spring Frost First Fall Frost Frost-Free Days
Conservative (safest) May 18 Oct 16 151 days
Cautious May 13 Oct 10 150 days
Average year May 4 Oct 6 155 days
