In a typical year, the last spring freeze around High Point comes near March 30 and the first fall freeze near November 5. One year in ten, a freeze still arrives after April 15 in spring — and one year in ten, the first fall freeze has already landed by October 21. NCEI's own growing-season statistic (days between freezes, percentiled per year) puts the median at 220 days.

The year at a glance: blue bands span the 9-in-10 to 1-in-10 range where the last spring / first fall 32°F freeze lands; the green band is the typical frost-free window between the median dates. Measured at High Pt, NC (USC00314063), 2.1 mi from the city's census reference point, elev. 900 ft. NOAA/NCEI 1991–2020 normals.

Measured at High Pt, NC (USC00314063), 2.1 mi from the city's census reference point, elev. 900 ft. NOAA/NCEI 1991–2020 normals. Read each date column as odds over the 30-year record — e.g. "9 in 10 years past by" means only one spring in ten saw a later freeze than that date.

Pure arithmetic on the freeze-date percentiles above — the "cautious" window opens on the date only 1 year in 10 still sees a later spring freeze, and closes on the date by which only 1 year in 10 has already frozen.
