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 9 | Oct 31 | 175 days |
| Cautious | Apr 27 | Oct 25 | 181 days |
| Average year | Apr 22 | Oct 20 | 181 days |
| Optimistic | Apr 16 | Oct 16 | 183 days |
| Aggressive (risky) | Apr 8 | Oct 7 | 182 days |
Not very — frost dates can vary by ±30 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 2 days per decade). Use the "Conservative" dates and choose fast-maturing varieties.

Sunlight & Day Length in Madison County
Monthly daylight hours and peak sun — critical for onion varieties, photoperiod-sensitive plants, and solar garden planning.
What this means for you: You can't change the sun. Picking the right day-length-matched varieties for Madison County matters more than any other "fix" you make — and the seed packet tells you (look for "long-day," "short-day," "day-neutral").
Longest Day

Peak Sun Hours
9.4 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 long summer days (14+ hours) support long-day onion varieties like Walla Walla, Sweet Spanish, and Ailsa Craig.

Insect Pest Pressure
Moderate — common pests appear but manageable with monitoring.
Disease Risk
Moderate — watch for mildew and blight during wet periods.
Seasonal Risk

| Pest | Risk Level | Peak Months |

Organic pest management tips
- Use row covers on susceptible crops during peak pest months
- Apply neem oil preventatively every 7-14 days during active pest season
- Interplant with strong-scented herbs (basil, marigold) to confuse pests
- Hand-pick larger pests (beetles, caterpillars) in early morning when they're sluggish
- Practice crop rotation — never plant the same family in the same spot within 3 years

Wind & Microclimate in Madison County
What this means for you: Wind is the silent water thief. Every breeze pulls moisture from leaves and soil. Madison County's 9.3 mph average is one piece of the watering math: rainfall + irrigation must exceed evaporation + transpiration, and wind boosts both losses.
Wind dries soil, stresses plants, and affects frost patterns. Understanding your exposure helps with garden placement.

Spring: 11 mph Summer: 9 mph
Fall: 10 mph Winter: 11 mph
Prevailing wind: SW. Moderate wind — consider a temporary windbreak for young seedlings.
Windbreak Benefit
5.1/10
Moderately beneficial — a simple fence or trellis can protect delicate crops from wind stress.
Frost Pocket Risk
Low
Relatively flat terrain (152 ft range). Frost pocket risk is minimal — garden placement is flexible.
