Frost Risk Probability

Based on 29 years of NOAA weather station data from 3 stations

Too early frost risk Safe to Plant Feb 14 → Dec 2 292 frost-free days Protect crops frost returns Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec Safe: Mar 8 Protect by: Dec 22

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 8 Dec 22 289 days
Cautious Feb 27 Dec 9 285 days

How predictable are frost dates here?

Not very — frost dates can vary by ±60 days year-to-year. Use the "Conservative" row in the table below, and keep row covers handy for surprise late frosts.

⚠️
Is the growing season changing?

Yes — growing seasons are getting shorter here (about 5.6 days per decade). Use the "Conservative" dates and choose fast-maturing varieties.

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

Wind dries soil, stresses plants, and affects frost patterns. Understanding your exposure helps with garden placement.

Seasonal Wind Speed

Spring: 10 mph   Summer: 10 mph

Fall: 8 mph   Winter: 9 mph

Prevailing wind: W. Moderate wind — consider a temporary windbreak for young seedlings.

Windbreak Benefit

5.4/10

Moderately beneficial — a simple fence or trellis can protect delicate crops from wind stress.

Frost Pocket Risk

Moderate

Some terrain variation (431 ft range). Garden on slopes or higher ground if possible to avoid late-season frost pockets.

Rainwater Harvesting Potential

How much water you can collect, when to collect it, and what size system you need for your garden.

8 rain barrels (55 gal each)

For a typical 500 sq ft garden. Serious collectors: consider a 2,500 gal tank.

Legal Status

Unrestricted

Rainwater harvesting is fully legal in your state with no restrictions.

Best Collection Months

Jan, Feb, Mar, Dec

Highest rainfall months — your barrels will fill up quickly during these months.

Months to Draw From Storage

May, Jun, Jul, Aug, Sep, Oct

Dry months when you'll rely on stored water — size your storage for this gap.
