Dateslast Frost Date
A precise tool.
What is the Dateslast Frost Date & How does it work?
The last frost date marks the final day in spring when temperatures drop low enough to damage tender vegetation. Knowing this date helps gardeners and farmers plan planting schedules to avoid frost damage.
Meteorologists compile daily temperature records over many years and identify the latest day each year when the minimum temperature falls below 0 °C (32 °F). By averaging these dates, we obtain a climatological estimate for a specific location.
Statistical averaging smooths out year‑to‑year variability, yielding a reliable guide for agricultural timing. The calculation can be expressed as:
\frac{1}{n}\sum_{i=1}^{n} D_i
F = average last frost day of year
