Frost Risk Probability
Based on 29 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) | Jun 19 | Oct 22 | 125 days |
| Cautious | Jun 8 | Oct 3 | 117 days |
| Average year | May 23 | Sep 23 | 123 days |
| Optimistic | May 16 | Sep 10 | 117 days |
| Aggressive (risky) | May 1 | Sep 1 | 123 days |
Not very — frost dates can vary by ±49 days year-to-year. Use the "Conservative" row in the table below, and keep row covers handy for surprise late frosts.
Slightly — seasons are trending a bit longer (0.7 days/decade). Historical frost dates are still reliable for planning.
