Disclaimer

Last updated: July 2026

Short version: Frost dates on this site are historical probabilities, not guarantees. Local microclimates and year-to-year weather vary widely. Use this planner as general gardening guidance only — always confirm timing against a current local forecast before making planting decisions.

Estimates only — no guarantee of accuracy

The frost dates and planting windows produced by Garden Frost Date Planner are estimates derived from historical climate data. A typical "average last frost" date reflects a statistical probability across many years — commonly a 50% chance of frost occurring after that date — not a promise that frost will or will not occur in any given season.

We make no warranty or representation, express or implied, regarding the accuracy, completeness, reliability, or suitability of any date, schedule, or information provided on this site. You rely on the results entirely at your own risk.

Microclimates and weather vary

Historical averages cannot account for the conditions in your specific garden. Actual frost timing is affected by many local factors:

Microclimates created by elevation, slope, tree cover, walls, pavement, and bodies of water
Year-to-year weather swings, cold snaps, and late or early frosts
Your exact location relative to the nearest weather station used for the underlying data
Urban heat, frost pockets, and other very local effects

Use as planning guidance only

Important: Treat this planner as a starting point for planning, not a substitute for a current forecast. Before sowing, transplanting, or leaving tender plants unprotected, check your local National Weather Service forecast and consult your regional university agricultural extension office. When frost is possible, protect vulnerable plants.
