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 22 | Nov 15 | 207 days |
| Cautious | Apr 15 | Nov 5 | 204 days |
| Average year | Apr 9 | Oct 28 | 202 days |
| Optimistic | Apr 4 | Oct 23 | 202 days |
| Aggressive (risky) | Mar 19 | Oct 15 | 210 days |
Not very — frost dates can vary by ±34 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 1.9 days per decade). Use the "Conservative" dates and choose fast-maturing varieties.
