About Frost Date Estimates
The frost dates provided are statistical estimates based on historical weather data and should be used as general guidelines only. Actual frost dates can vary significantly due to:
- Microclimates: Local terrain, buildings, water bodies, and elevation can create unique conditions that differ from regional averages
- Annual weather variations: Climate patterns change year to year
- Urban heat islands: City areas often experience later first frosts and earlier last frosts
For the most accurate information specific to your garden: Consult your local nursery or garden center. Their experience with local growing conditions is invaluable and can provide insights that no calculator can match.
