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 24 | Nov 10 | 170 days |
| Cautious | May 13 | Oct 30 | 170 days |
| Average year | May 4 | Oct 22 | 171 days |
| Optimistic | Apr 28 | Oct 11 | 166 days |
| Aggressive (risky) | Apr 22 | Oct 1 | 162 days |
Not very — frost dates can vary by ±31 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 (0.8 days/decade). Historical frost dates are still reliable for planning.
Gardening Difficulty Score
Erie County offers good growing conditions. A little planning around frost dates goes a long way.
