Frost Risk Probability
Based on 31 years of NOAA weather station data from 3 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) | Mar 11 | Dec 18 | 282 days |
| Cautious | Mar 5 | Dec 7 | 277 days |
| Average year | Feb 25 | Dec 1 | 279 days |
| Optimistic | Feb 12 | Nov 22 | 283 days |
| Aggressive (risky) | Jan 29 | Nov 13 | 288 days |
Not very — frost dates can vary by ±42 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 1.7 days per decade). Spring is arriving earlier than it used to. Good news for gardeners.
