Frost Risk Probability
Based on 30 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 19 | Dec 19 | 244 days |
| Cautious | Apr 8 | Dec 7 | 243 days |
| Average year | Mar 8 | Nov 25 | 262 days |
| Optimistic | Feb 5 | Nov 9 | 277 days |
| Aggressive (risky) | Jan 6 | Oct 28 | 295 days |
Not very — frost dates can vary by ±104 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 17.2 days per decade). Use the "Conservative" dates and choose fast-maturing varieties.
