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) | Apr 5 | Nov 30 | 239 days |
| Cautious | Mar 21 | Nov 21 | 245 days |
| Average year | Mar 13 | Nov 14 | 246 days |
| Optimistic | Mar 5 | Nov 4 | 244 days |
| Aggressive (risky) | Feb 18 | Oct 27 | 251 days |
Not very — frost dates can vary by ±46 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.
