NOAA tracked 30 years of freeze dates at your nearest weather station. This is the typical last spring frost and first fall frost derived from that record, given as a range, not a single guessed date — and not a substitute for your own yard's microclimate, which can run days or weeks off the station reading.

How to read the three dates

  1. Early (10% of years). The riskiest date to plant tender crops by, frost has still hit this late in roughly one year out of ten.
  2. Typical (50% of years). The median date this site leads with. Even odds, historically, that frost falls before or after it.
  3. Late (90% of years). The safer date. Waiting this long cuts the odds of a frost afterward to about one year in ten.

Why this gives a range, not a date

Search "when is the last frost near me" and most results hand back a single date, as if a 30-year climate record were a promise. It isn't. FrostDateCheck reports what NOAA's own normals actually show: a typical date, and how much that date moves year to year, so a planting decision can be made with the real odds instead of a guess.

What a ZIP code page adds

Every page pairs the USDA Plant Hardiness Zone for that location with NOAA's frost-probability dates from the nearest reporting station, plus where it ranks nationally by growing-season length. Neither figure is this exact address's own weather station in most cases, both are named and linked to the source.
