The year, day by day
Vienna works both ends of the calendar. Normal highs climb to 90°F by July 11 and hold at or above 90°F on 21 dates, then normal lows drop to freezing or below on 84 dates, bottoming at 27°F around January 26.
When the heat sits
Normal highs reach 90°F from July 6 through July 26, covering 21 dates. The broader mild season, normal highs of 70°F or more, runs April 17 to October 21.
This counts calendar dates whose 1991–2020 normal high reaches 90°F. It is a smaller number than the 90°F+ day counts in the monthly table above, which measure how often the threshold was actually crossed in a typical year. A date can average 88°F and still exceed 90°F in half of all years.
The freezing stretch
The normal low stays at or below 32°F into March 2, then returns to freezing around December 10, covering 84 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
April 18 carries the biggest normal gap between afternoon and dawn, 26°F between the normal high and the normal low.

Data-derived climate profile
How Vienna's climate pattern fits together
heating led · mid swing
Vienna's energy balance leans toward cold weather: 3,892 annual heating degree days against 1,488 for cooling. Its 41.7°F seasonal range still makes the monthly rows more useful than the annual average alone.
Vienna's frost-free season lasts about 210 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 Vienna's middle-range seasonal profile. The measured spread is 41.7°F. The annual average is 58°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
A moisture-range label is withheld because Vienna'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 Vienna'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 Vienna, not an official NOAA class or a year-ahead forecast.

Data Sources
Data source: NOAA U.S. Climate Normals v1.0.1 (1991-2020). All figures on this page are from Vienna's primary station: VIENNA (USC00189140). For informational purposes only.
Place identity: U.S. Census Bureau 2024 Gazetteer places. The 2024 Census Gazetteer identifies the exact name-and-state match as an incorporated place (GEOID 2480600). Match rule for Vienna: exact normalized name + state only, no fuzzy expansion, so nearby differently spelled facilities stay unmatched.
On this page every temperature, precipitation, and derived score for Vienna comes from its primary NOAA station record. No figure on this page is typed in by an editor - each value is rendered from NOAA 1991-2020 U.S. Climate Normals.
