About USFrostDates

USFrostDates provides US frost-date tables and planting calculators using public climate records.

Our goal is simple: help you understand the range of dates behind the first and last frost dates, find the station behind the number, and make your own planting plan.

We are an independent data project, not a weather forecasting service. We do not claim that a date makes every crop safe to plant. The reference period, probability and local conditions matter.

Available data and tools

You can browse every local guide without an account, compare three historical probabilities, download the dates and export your own planting reminders. Sources remain a click away.
