When is the last spring freeze — and the first fall one?
Freeze-date odds for 380 US cities, straight from the NOAA/NCEI 1991–2020 climate normals: the typical (median) last spring and first fall freeze, the 1-in-10 early and late tails, three temperature thresholds, and the frost-free window between — each city measured at its named nearby station, with the distance shown. Dates and probabilities only; here is exactly how to read them.
