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) | May 7 | Dec 18 | 225 days |
| Cautious | Apr 19 | Dec 1 | 226 days |
| Average year | Apr 11 | Nov 22 | 225 days |
| Optimistic | Mar 29 | Nov 9 | 225 days |
| Aggressive (risky) | Feb 12 | Oct 27 | 257 days |
Not very — frost dates can vary by ±85 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 shorter here (about 7.6 days per decade). Use the "Conservative" dates and choose fast-maturing varieties.
