Frost Risk Probability
Based on 31 years of NOAA weather station data from 2 stations
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) | Apr 18 | Nov 27 | 223 days |
| Cautious | Apr 7 | Nov 15 | 222 days |
| Average year | Mar 29 | Nov 11 | 227 days |
| Optimistic | Mar 19 | Oct 28 | 223 days |
| Aggressive (risky) | Mar 1 | Oct 19 | 232 days |
Not very — frost dates can vary by ±48 days year-to-year. Use the "Conservative" row in the table below, and keep row covers handy for surprise late frosts.
Yes — growing seasons are getting longer here (about 7.7 days per decade). Spring is arriving earlier than it used to. Good news for gardeners.
