The freezing stretch
The normal low stays at or below 32°F into March 24, then returns to freezing around November 16, covering 130 dates in all.
Derived from the normal daily minimum. This is a different measure from the 50%-probability frost dates shown elsewhere on this page, which come from NOAA’s frost product.
The widest day
March 28 carries the biggest normal gap between afternoon and dawn, 21°F between the normal high and the normal low.

Data-derived climate profile
How Blowing Rock's climate pattern fits together
heating led · mid swing
Blowing Rock's energy balance leans toward cold weather: 5,796 annual heating degree days against 287 for cooling. Its 38.5°F seasonal range still makes the monthly rows more useful than the annual average alone.
Blowing Rock's frost-free season lasts about 179 days, a middle-length window whose endpoints matter more than the annual average. It describes freeze probability, not year-specific planting conditions.
July and January mark the typical warm and cold ends of the calendar in Blowing Rock's middle-range seasonal profile. The measured spread is 38.5°F. The annual average is 50°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
A moisture-range label is withheld because Blowing Rock's annual precipitation total is unavailable. Monthly source values remain visible where NOAA provides them, and no annual amount is reconstructed from incomplete data.
These labels group NOAA 1991-2020 normals from Blowing Rock's primary station, so the winter figures are a thirty-year average and not a floor: a single hard season can run well below them. Treat each band as a descriptive range for Blowing Rock, not an official NOAA class or a year-ahead forecast.
