How to read these numbers
Published 1991–2020 NOAA station normals, not a forecast or a guarantee for an individual garden. Spring dates express probability of the last threshold occurrence on that date or later; fall dates express probability of the first occurrence on that date or earlier. Growing-season length expresses the probability of at least that many days and is independently published: it is not computed by subtracting the two date quantiles. Published MM/DD calendar dates are preserved; leap-year ordinals are only an internal plotting coordinate. Local terrain and distance from a station matter. Special no-freeze, year-round risk and missing values are unavailable rather than fabricated dates.
Map colors span the minimum and maximum available values in your current filters. Point maps locate reference points and do not shade geographic boundaries. Nearby ordering uses straight-line point distance, not a travel route. Public links preserve statistical filters and place identifiers; calculation amounts and search text stay out of the URL.

Exact 1991–2020 v1.0.1 published station freeze/frost probability values for thresholds 28/32/36°F and probabilities 10/50/90%; 50 states/DC. Published spring/fall MM/DD strings convert to leap-calendar ordinals internally and back to calendar dates for display. Special missing codes remain null; raw values and completeness flags are retained. Archived losslessly as gzip; uncompressedSha256 identifies extracted content.
