Frost Risk Probability
Based on 16 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) | Mar 4 | Dec 27 | 298 days |
| Cautious | Feb 13 | Dec 25 | 315 days |
| Average year | Feb 4 | Dec 22 | 321 days |
| Optimistic | Jan 17 | Dec 16 | 333 days |
| Aggressive (risky) | Jan 10 | Dec 4 | 328 days |
Not very — frost dates can vary by ±54 days year-to-year. Use the "Conservative" row in the table below, and keep row covers handy for surprise late frosts.

Peak Sun Hours
9.8 hr/day peak (summer)
Peak sun hours (green dashed line below) account for cloud cover — this is the usable direct sunlight your garden actually receives. Most vegetables need 6+ peak sun hours.
Onion tip: Your shorter days favor short-day onion varieties like Vidalia, Texas 1015, and Red Creole. Plant in fall for best results.
